I've had my B6 A4 3.0 quattro for about 3 years now and I've been having a twitch for something new. I've got the A4 exactly how i wanted it, looks fantastic, performs well, great spec. Replacing was going to be a hard job! Also as i've spent a fortune on it, always using all genuine parts throughout and solving problems and modifying as i go it is set to last another 100k miles again. heres my work in 3 years

before:

after:


i have always felt that for an estate car the boot was pretty small, the cabin wasn't overly spacious, but that was made up by the almost hatchback styling on the outside that looked very sporty. i wasn't really interested in an A6 as always thought they looked a bit blobby and boulbus... but then a friend of mine put his S6 up for sale so thought i'd go and have a look. Again, never really liked the a6/s6 for its looks and always thought it was blobby compared to the sleek B6, and always thought as the C5 was the last of the old generation and the B6 was the first of the new generation they always looked a bit dated.

But went and saw it anyway! And bought it lol

Anyone thats seen Jordan_Turbos thread already then this is going to be a bit of a repeat, but if not welcome :)

It is pretty MEGA spec! its on a whole new level from the A4, but i suppose new it was on a whole new price level too!
2001 widebody 4.2 V8 S6 Avaunt, its got full leather recaro seats, electric and heated on the front, front and rear parking sensors, self leveling xenon headlights with washers, cruise, trip, blinds in the rear door cards, real carbon fibre trim everywhere, alcantara headlining and pillars, all black plastics inside, ISOFIX, pas airbag deactivation, 20inch alloys, it goes on and on.....

In Jordans ownership he concentrated on speccing it up even more! he added the newer RNS-E audi satnav stereo, this thing on its own is a bit of a mind blower, its fully integrated into the car and the satnav commands even comes up on the DIS display





He also added TVs into the rear headrests for the kids, linked to a DVD player in the glovebox, this dvd player can even be played on the front screen too





on the performance front he fitted 350mm 6 pot monster brakes! (although they do look a little lost behind the 20s!



he also fitted eibach coilovers which gives it a great stance. with future adjustment possible :)

The thing that sold it for me was the inside. sitting in it you feel like a king, the seats are amazing and everything ozzes quality! Jordan freely admitted he much preferred driving it to cleaning it, so it is in need of some pretty mega tlc.

If anyone has seen my quality of work they can expect much more on that,rest assured, i have great plans for this! :jump:

Very nice. I too went from a B6 to a C5, and in honesty there are very few things I miss about the A4. I look forward to seeing your plans unfold.
 
a few things i need to change to suit my needs as much as i would love this to just be a toy, it will be a family car and a general commuter (lucky i only live 4 miles from work!).

The exhaust is VERY LOUD. it sounds amazing, pornografic infact! a little vid ( dropped the quality right down unfortunatly :( )



but its going to be a bit loud when im coming home from work at 5 in the morning and reversing up the driveway. its had all 4 cats removed and it used to have straight through rear system, but Jordan did have rear boxes fitted to quienten it down a bit. it must of been savage before :eek: i spotted a genuine RS6 stainless exhaust for cheap on e bay and noticed it was right near where i was going to pick up some wood on a roadtrip, so aquired that







The other problem quite obviously with a 335+bhp 4.2 V8 is fuel economy. So yesterday i made my way up to Leicester to a specialist LPG place. the problem i face is the power i am trying to contend with. 4cyl kits usually go upto about 180bhp, 6cyl kits usually 250bhp and 8cyl kits upto about 300bhp. so i needed to go to the next stage and went all out with a really advanced performance system which will do me nicely :)

I decided to take my inlet with me so we could have a good measure up of injector length and sizes. Started stripping down the top halfs and these really are a new ball game of engines. theres flaps and valves everywhere!





even the airbox has got a flap in it (what ever it does?!)



inlet in a box



and a 3hour trip up to Leicester. alot of fun shopping and brought back some presents



i got the biggest tank i could fit in the spare wheel well. 95litre tank (will hold about 80 litres as lpg tanks dont completly fill) my white one holds 50 litres and can do about 200 miles on that so this should give a bit more. this is a BIG tank



hana high performance individual injectors and link bars



loads of gas pipes big and small, water pipes, vaucuum, fittings and filler



KME high performance regulator, anodized gold equils an extra 5bhp :cool:



and the brains to control it all. LPGtech top ecu. its watches the injector timing and also links into the cars CANBUS system to adjust itself.



With this system throttle response and bhp will be pretty much on par with petrol. not the usual 10% drop usually associated with lpg kits.

they even included a goody bag, LPG energy drinks lmao

will be interesting to see how you get on with the LPG.

what's the ball park figure for the kit if you don't mind me asking??


amazing how similar Audi have made their range of cars when you see them side by side... the 4 looks the exact same almost as the 6 in those pictures... well to me anyway! lol
 
This will be my 5th LPG conversion so shouldn't have any problems, i am hoping to get all the injectors hidden under the big plastic centre cover, and i found you can get a 3.0 cover for the n/s with the A6 to cover where i will put the regulator. so the lpg conversion will be completely hidden :)



im looking forward to seeing how this new generation of lpg kits perform :) the whole kit came in at just under £600. that's including the tank and every clip hose screw and fitting i will need. he did me a cracking deal as we bought so much (my dad bought a smaller kit too) adding it all up online it should have been more £800+.

This is a hell of alot bigget than my A4. i never realised the difference before putting the two side by side. its bigger everywhere. in the front theres alot more room between you and the screen, the boot is alot bigger, both wider and alot deeper, and the biggest notice is the rear seat footwells, its like a limosine compared to the A4. not sure if the wide body S6 is any bigger than the A6 at all?

thanks for the LPG info... :D

Oh I know it's bigger than the 4... just soooo boring that it looks the exact same...typical Audi though!

I think the wide body S6 just has the arches of the RS6 so the actual size of the normal car is the same?!?!? not totally sure though, I know my RS6 is a lot smaller than my S8 in length and interior space... probably bigger width wise mind you...

Car looks great. I was in the same mind as you as I've never really liked the a6 and prefered the looks of the b6 a4 so I bought one lol. Although saying that the car looks great and you always do good work! SUBSCRIBED! Lol
 
now for something not really essential but it can sometimes become a long process. When Jordan bought the car it had the following private plate on



He then put his private plate on for the duration of his ownership and took it off when I bought it. Now, we thought it would have gone back to an age relate 51 plate numberplate as he didn't pay for the above plate to be saved.

However when the logbook came though it was on the T6 TEU private plate. The dvla said if I send it back they can put it on the origional plate it was registered on LJ51 DNF for free and then the T6 TEU plate would just go back in their system.
Just out of curiosity I did a couple of quotes on the private plate sites for T6 TEU and they were estimating £500+ for it. :O so a few phone calls and a plan was hatched. I found it was only £80 to put the T6 TEU plate on retension for 10 years and the reg sites will put it up for free at £500 and take 20% commission when its sold, minus the £80 retension fee leaves me with £320 in my pocket. Armed with this info in mind i started looking on the dvla site at private reg's and came across this one in the bargain basement £250 pile



So once the other one actually sells, i'll be £70 in profit :cool: which no doubt will go straight in the gas tank lmao.

My initials are RC for anyone that didn't know. and with the standard style of numberplate font it actually looks like there is a bit of a space between C and X resulting in 'S6 RC X' without any dodgy spacing :)
 
had a spare hour tonight so i thought id get the nozzles in the inlet sorted. this is the main bit in a lpg conversion you can **** up and not be able to un ****. if you drill these wrong its time for a new inlet. ****** expensive here.

the closer you get the nozzles to the petrol injectors the better, as ultimately the closer the gas injector is to the petrol injector the more accurately it can follow it. if this differance is really long then you can get a delay too. Also they recon if its more than 30cm away it will restrict you high revs. and the distance between the injector and nozzle must also be the same.

on my white one they were put on the elbow for ease and they have a fixed rail so to keep all the pipes the same length they need to be looped out abit. not ideal but this is a normal way of doing it





with this install i am really going to town and wanted the distance as short as possible, hence buying individual injectors. i started drilling and tapping for the nozzles. i taped up everything underneith and bunged all holes and did it in situ so i could get the correct angles







nice and close to the petrol injectors :)



which ment i could mount the Hana individual injectors nearly right to the nozzles with only a tiny stump of hose





and with those 4 all mounted below fuel rail height it means this fits straight back on with no mods :) :)



those 4 injectors then go to this splitter bar but the distances here arent important as its all constant pressure before the injectors. hopefully these will fit under the plastic covers that hide the coils



and did the other side too. all 8 nozzles done :)



so all in all happy. the aluminium inlet is very thin so wasn't alot of room for error with the tapping.

i will be fully degreasing the inlet inside and out to get rid of any swarf, and probably give it a lick of paint too.

Great work bud :) but have to ask, what are your plans for the old exhaust? I'm on the lookout for a donor to mod onto my 2.5 Allroad :ninja:
 
cheers :) yea I'll be selling the old system on i recon. its got a powerflow recipt for £250 in with the paperwork not long been done.
 
Well they said the plate will come through in 4-6weeks which is why I ordered it Monday to get things rolling, and it turned up this morning, 2days later :lmao:

 
i had another couple of purchases come through so popped up there for 5 mins to fit.

the number plate lights and front side lights were pretty drab brown bulbs so I've brought it into the 21st century with some LEDS.



the standard number plate lights (much browner in real life)



and blinging LEDS



and the standard fronts, look even worst next to the standard xenons



and LEDs



you can see in the above pic how scratched the lights are, lots of polishing ahead!

while i was there i pondered a bit about where to put the regulator for the gas. This is the area i was hoping



little bracket fabrication



and in with plenty of room. i also chopped up the abs pump bracket a bit to allow me to fit the lpgtech ecu in there too.



and with the little power steering cover back on its nice and neat :)



i was on the lookout for a audi A6 3.0 n/s power steering/washer bottle cover to hide the whole lot over that side, i have the same on my 3.0 a4



but more recently found the ones out of the passat have perforated holes which match the rest of my V8 covers



so would cover the power steering/washer bottle and cover the lpg bits too and alk match



only problem is my dipstick is over that side and will be covered.

Gimme a shout if you do (and the price is right) and I may have that off you mate :)
 
had another little wiggle on it tonight. i worked out where everythings going pipewise in the bay to do with the lpg. lengths dont really matter this side of the injectors as its all constant pressure rail before the injectors





and loops back around to the regulator



now you maybe wondering why i haven't gone to more effort to keep all the pipes parallel and square to each other, its because my main aim was to keep them all as flat as possible.... resulting in all the covers going back on :)





lpg? what lpg :cool:

i will now strip it all down again as i want to change the rocker gaskets and paint the inlet manifold.

so for now i thought id have a little look at the tank to go in the spare wheel well.



these do have a mega deep wheel well with the extra layer for the rear seats



stripped it all out and found the 7 seater bit is actually all bolt in. so could remove it if i needed to and have a lower standard floor



and also found this freaky piece of something looking up at me, was the size of a 1p



i was sticking my head underneith to see where would be the best place to drill a hole and caught a glimpse of something... hmmmmm.... Couldn't be could it??.....

whipped the rear bumper off and would you believe it... its got a factory tow bar fitted, never used!





its got the spring loaded arm to flip the electrics down and hide when bot in use





but its never had electric socket bolted to it.

it was all hidden behind the lower bumper trim, there must be a different one with a cutout for tow bar models



so great news, saved a packet on a tow bar, these westfalia vertical ones are still £400-500 new.

bad news, just this morning i bought this :lmao: :(

got my towbar through today, even came with the fixing bolts :)



moment of truth, tried it on my 'unused' beam, and horrah it fits :)



tried the bumper on and it all clears, not cutting of the bumper required



and all hides completely invisable

on



off



even got an audi cap :cool:



one thing i may not use is the electrics as its got a 13pin euro plug. they are the future, but all the trailers i use are 7 pin and its a pain using an adapter all the time, not sure on that one yet



and can comfirm my beam has never been wired up, as ive found the gromit the wires go through



id noticed its been leaking a bit of coolant since its been sitting here, leaving a puddle on the floor. traced it down to the top radiator hose.



so a little trip to TPS today and got a new O-ring for it, and also going to do the rocker cover gaskets while the engine bay is all in pieces as they are weeping, and i know the stink they give from the white one when they start dripping on the manifolds

 
Lots of work being carried out As usual and to a high standard as always. Has the b6 gone yet?

Thanks. not putting the white one up for sale untill this one is ready. then when its sold I'll transfer all the insurance over to this one. can't afford to have two big audi estates on the run :noway:

having a bit of trouble with the private plate as it looks like it needs to be taxed and insured to get the old plate off to keep, gonna have to ring them and see if there's a way around it.
 
Gave the audi a visit again tonight.
The rocker covers were weeping so i thought id do them now before it gets worse as they're a pain to do when its all together



so got them off, drivers side



then took the passenger side of and found a bit of a wierd one. the drivers side has the cam link chains at the back and the passenger has them at the front, infact all the sensors look to be opposite ends, and the gaskets fit either side too, its like they only make one head and then spin it around



i was pleased to find no sludge build up or nasty deposits in there, a credit to the previous owners giving it plenty of oil changes using quality oil



gave the covers and bolts a good clean up


and back on with new genuine gaskets





much better, and hope it will stay like that



started rubbing down the inlet ready for paint. didnt bother with the rocker covers as they're all hidden under the plastic covers.



:)

My OCD wouldn't have let me refit the cam covers without painting them regardless of being able to see them or not lol. Top work as ever Ron.
 
I'm surprised you didn't paint them, I didn't think you would have been able to resist.

Whoever buys your white one is going to get a great car, and I can imagine the first to view it will buy it.

I wrote them a nice letter and they let me take my plate off the old car after I had SORN it so hopefully you'll be ok too.
 
I've been having some trouble getting the whopping 95litre lpg tank in the wheel well. my measurements are spot on, the tank is the exact size of the wheel well. What i hadn't factored in was where the boot catch is there is an overhang over the wheel well meaning the tank cant drop straight down in, and at the angle trying to slide it in the diagonal of the tank is longer and how ever much i tried it just wouldn't go in.
The other problem was the outlet comes out the side, and the wheel well is surrounded by bulk, the diff and arb at 12 o'clock, exhaust coming past at 10 and 2 o'clock, exhaust back boxes at 9 and 3 o'clock, tow bar at 6 o'clock, tow socket at 7 o'clock and rear tow eye at 5 o'clock. I decided i could fit in in just at about 7-8 o'clock so made the hole for the exit to come through.



but still as much as i tried it just wouldn't clear the top of the rear panel to get it in, thats when things got serious :lol:







once the tank is in the rear panel clears fine, so i will have to put it in and then weld the rear panel back on after.

i started making the plate up to go around the tank exit



but wasn't happy how it was sitting on the curve with clearances so went all out :eek:



don't panic though, i was 8 years as a panel beater so will all be going back together seamless :) got a nice bit of c.a.d going on



I didn't have any zinc primer so left it there for today and carried on with the inlet manifold.
I didn't like the way it was all stippled aluminum the older style manifolds are, i like the newer style plastic smooth inlets, like on my 3.0, so i flatted all the top down (all that's on show with the covers on, took ****** ages) and primed it up



gave it a lick over with some vauxhall star silver



flatted it back and lacquered





exactly what i was looking for :) :)

I admire your commitment, but could you not have just swapped the tank for a slightly smaller one ha ha.
 
stared boxing in the area for the filler tonight. didnt get as far as i hoped, but still progressed







stonechipped all the inside up



then wax oiled it all up to stop any corrosion between the tank and well



all ready for the tank to go in one last time and well the section back in. but sadly ran out of time. took a pic to show the clearance ive achieved for the filler and pipes, the rear pannel was symmetrical

got the tank back in and started making the brackets





took it back out and fully welded them up



and painted it all up



went to bolt it down and found the rear hole is actually inside a cross member, ******! so hole cut a 19mm hole and welded a nut in flush



and back in and bolted down for the last time ever!



started tacking the rear panel back together. made sure every corner lined up, i was still very tight to the tank and had to put a bow in the lower section.



tried the tow bar on to see if the bow was a problem

loads of room



and then put the boot rubber back on and the moment of truth.... straight down on the catch :) :)



so cracked on and welded it all up





good penertration and welded round both skins



and took it all down. lined up so well it nearly all metal finished





then etched it and sealed it all up inside and out





will stonechip it all up once the sealer is dry and will look good as new :)

and all back whole again :)

Managed to sneak down there this morning before the wife woke up.

next on the list is to have a look at swapping the exhaust for the RS6 item and to run the copper lpg line down the car. Its been sitting on a trailer bed so has been at an angle, not ideal for jacking up, so jacked the whole bed up level then jacked the car up on that





this is the first time ive actually looked under it properly so had a good poke around. found quite a few leaks from various places, engine and gearbox sump pans have quite big leaks leaving drops on the floor, looks to be only the gaskets so not to bad to do



but theres quite a big leak from the transferbox prop seal



will have to investigate how much of a job to do this seal. obviously ill have to drop off the prop, but all the exhaust is off and out the way and if its only like a crank seal i'll probable get it done

had a look at the exhaust too and found the de-cats, basically they've cut the cats out and welded pipes back in. on one side the flexy must of been knackered as they've put a longer pipe in that side so only one side had got a flexy, not ideal as thats alot of strain up on the manifold join. might put a little flexy back in.



inspection complete so i moved on to getting the exhaust off, looked at the joiners.... no chance



choppy choppy



got the RS6 exhaust out of the corner and thought id have a little look how it cleaned up







amazing quality stainless, this came off a 2003 car



and the two together





quite a bit more gurth ;)




and on





lines up exatly the came place, just need to get some reducer joiners

 
took it back off and painted the rear panel back up





then i could bolt the sender unit in the tank




and in



and it has a nice little cover that clips on and keeps everything clean



tried the tow bar on and loads of clearance

 
had to pop in earlier so just tried the S6 bumper over the RS6 exhaust. I've read from others that they are slightly too wide and just need a little trim of the valence.



yep too wide, but they are fully adjustable on the slider



and only looks like its gonna need a little trim on the corners :)

Todays task was to run the copper line from the tank to the regulator down the front. not exactly an easy job on these with the rear subframe, exhausts fuel tank etc etc, as you want to run the line as close to the body as possible so if you ever want to work on anything and remove anything its not tangled up in the gas line



the rubber lined copper 8mm pipe.



i whipped the front bumper off for better access



with the wheels off its gave a chance for a better look at the monster 6 pots, they always look small in the wheels (20s) so got a pic with some perspective





onto the gas line

started at the tank



down the floorpan



and up to the regulator at the front. basically just followed the brake lines down the car



there needs to be two looms run back to the tank too for the ecu. one is the shoutoff solenoid and one for the fuel level gauge



i telsa taped them together and ran it down the car tot he front





it doesn't seem alot of progress, buts thats about 5 hours work there!!

thought i'd put the boot bits back in, had to cut the rear trim around the tank





and then cut the carpet in around the tank brackets, it went in really well :)







the centre panel will fit in so it will all be invisible once back together.

got to take the carpet back out to the boot to fit the tow bar, and wax inject all the rear pannel etc i welded in.

also got the reducers for the exhausts through :)

I've come to a bit of a halt on the lpg front, I've glued the nozzles securely in the freshly painted manifold and the injectors need to go on before its fitted as they sit under the petrol fuel rail



got some clips to secure the pipes



but they're just a tiny bit too small :( going to have to order the next size up

next went to fit the water pipes to the lpg regulator, they T into the heater matrix pipes, but the t-pieces that came with the kit are too small for my matrix pipes :( so need to get the next side up

with the LPG on hold i set about some of the other jobs i need to do on the car (and found a few more)

the rear gearbox/transfer box leaking from the prop outlet i thought id give that a go first as the exhaust is already off, its just a case of undoing the heat shield and the props right there in front of you.

heat shields off



CV guard off and yep, leaky leaky



drained the transfer box fluid out



got the prop off to reveal this cheeky little bolt



and out, just like a driveshaft



and the seal, just like a crank seal



next i wanted to re paint the front calipers as they're a bit chipped now, but found a few more problems in this corner



first off when i jacked it up there was some major play in the track rod, had a look and it was the inner joint that was fubarred



something i also spotted and i want to change is on the drivers side on full lock the wheel actually rubs on the brake line, so going to somehow re route that forward a bit so it clears, its not very clear in the pic but the wheel touches by the union on the S



also spotted the CV boot is cracked all the way around so will get that sorted too



i want to get everything done while its off the road so when it is i can enjoy it once its all done :) luckily everything on the passenger side is all a-ok!

so stripped the brakes down a bit, these things are ****** HUGE!





took the discs off



and got the wire wheel out, used a drill bit to clean up the dimples



and sanded down the calipers too



Colour wise i think it will do the calipers in gloss black as that's what the RS6's etc have, I'm thinking of doing the discs silver this time, to 'mimic' the RS6 two piece discs, dont think it will look too bad.

The thing I'm humming about is what decals to put on, S6 or RS6. i know they're not offically RS6 front brakes but i think theyre big enough to get away with it? opinions?
 
I'd stick with S6 stickers, cos A, it isn't an RS6, and B, an S6 is nothing to be ashamed of.

I agree. I wouldn't put RS stickers on. Personally I'd go plain black stealth look but if decals is your think then S6 or Audi rings
 
i think i will put the S6 decals on as it turns out the RS6's only have RS on and not so keen on that



you can see the silver centres on these i will mimic.

the other option is to put porsche decals as the calipers are actually off a Porsche Cayannen :audibash: :shrug:

tried one of my 19s on this morning



but couldn't do up the bolts lol



had a look at the brake line the wheel rubs on full lock on the drivers side, a better pic



luckily i managed to manipulate it all in situ at clear that area, saved having to bleed it all up



i stripped out the passengers side brakes



the discs arent very old, they just spent alot of their life sitting



and all rubbed down ready



need to get some caliper paint now

got a bit o.c.d and started cleaning the prop heat shields too
