New owner of a very (very) high mileage 2006 Avant

[bunnyfunk]

Thought I'd say a quick "Hello" after lurking for a week or so.


As the title says, I'm a new owner of a very high mileage 2006 Quattro A4 Avant, which I believe is a limited edition TFSI.
It has the correct VIN and engine stamp from the Quattro GmbH plant, plus black headliner, black exhaust tips, black/grey full leather.


Although it's missing the alcantara handbrake, gear knob and steering wheel, plus no CD changer with silver (not black) roof rails and front bonnet trim.


I'm slowly fixing/renewing issues on it but so far it's been good.
Plus a little bonus, its running coilovers


I did want to pick peoples brains a little and ask:


-What were the original alloys that came on this edition?
--Along with the tyre sizing
And lastly-
-Recommendations for where to purchasing a flexi 3-bolt connector, downpipe and fittings?


I'll try and take some photos


Thanks
--Mark

Wheels on the special edition were intially Ronal's as also fitted to the DTM, but were changed to the speedline RS4 style rims on the later mk2 special edition, which had a few other body /trim changes such as more black trim etc, otherwise the same car.
18" 8j ET43 were the sizes of both rims used.
tyres were 235/40 18"

 

[Charlie Farley]

Mk1 special editions had silver brightwork but many owners changed it to black as it can look a bit poor after years in all weathers.
Mk2 had what is now called the black optic pack , black grille surround and door trims etc.
interior trim levels and finished varied on both versions as no two are the same from the factory and pack options varied a lot.

 

[tr7]

Congrats

So what's the mileage?

 

[bunnyfunk]

Thanks for the feedback Rob
Looks like I have MK1
And I have the MK2 Alloys on, which would make sense as the tyre shop said I should have 235/40/18 on but the tyre pressure plaque on the drivers max was 235/45/18 - yet I was running 225/40/18.

Any recommendations for finding a single RS4 style alloy as there is a crack in one of mine and I'm running a loaner?

Congrats

So what's the mileage?

187K

 

[Charlie Farley]

lots of the correct alloys around chap.
Yours is an early model as it has the amber indicators lens, they were changed to clear corners later in production of all B7's

 

[Charlie Farley]

Nothing wrong with a high milage car as long as all the bits that need fixing and replacing have been done.

 

[tr7]

Nice, nothing wrong with miles. I'd rather have a higher spec and maintained car with miles than a poverty spec with low miles.

Factory Xenons and Auto Lights/Wipers?

Damnit Rob - I can't unsee that now!
Might have to change those out

Had a full service done on Friday, a few error codes which we've cleared plus a leak on the downpipe, so losing back pressure.
Plan is to replace the downpipe this coming Friday along with the butterfly delete (???) and ECU update, check the error codes again.

After that, most likely the timing belt.

Need to pull a wheel off today and check the codes on the alloy

Factory Xenons and Auto Lights/Wipers?

Yes to the Xenons, no to the auto lights

 

[Charlie Farley]

clear corners do give the front end a fresher look, allmost modern..

 

[bunnyfunk]

Ohh I like that!
I think the silver on black suits the car, any other colour then the black trim would work!

Took an alloy off this morning to grad the codes, got presented with this:

No other real markings apart from this:

 

[tr7]

They're copies. Non original parts, and you'll have a nightmare finding another one the same as theres so many different types/versions

If you'd like a set of genuine Audi ones I have two sets I would sell cheap enough

 

[Charlie Farley]

Yep, safe to say with those very discreet marking's they are not genuine items..
Nothing wrong with aftermarket alloys though, just some are better than others and if you want something different from the few Audi ones that fit then its a good option, trust me , been there so many times on my old bus..lol

 

[bunnyfunk]

If you'd like a set of genuine Audi ones I have two sets I would sell cheap enough

..and that's probably why the centre caps I bought don't fit
Certainly interested, can you pm me the price?

 

[bunnyfunk]

Yep, safe to say with those very discreet marking's they are not genuine items..

I would have to agree!

 

[bunnyfunk]

Well..That's been a fun few weeks!
Quattro let me down on the day before my move with cylinder 3 misfiring so badly it wasn't safe to drive.


Picking up after the full service and fault code clearing, drove it around for a week before heading back to the mechanics to deal with the down-pipe and see what codes where back.


Soo...the down-pipe basically fell off - Good start and an easy change for the mechanic, he also changed out the boost control solenoid, low fuel pressure sensor and we cleared the codes again.


Managed to pick up a set of original alloys from @tr7 (thanks bud!) and had those wrapped in the correct size tyres - Yay!


Also in that time, I picked up a new revision diverter valve and a HPFP with a new tappet.


Back at the mechanic's, off with the old HPFP and the tappet was basically non-existent with the pump rod being also worn down.
On with the new and now with the correct fuel pressure, injector 3 was washing out the spark - Great!
Managed to order a replacement and the car was running ok.


Drove the car up North without too much of an issue - Bar the occasional loss of power just after 2K which comes back just below 3K <<--something to note as I've had this problem on/off since I've owned the car


Checked the codes after the drive and more high pressure fuel issues and along with the loss of power between 2K-3K - Ohh did I mention the sound of squealing piglets at the same time??


In with 4 brand new injectors, fuel pressure sensor and an RS4 fuel pressure regulator valve.


With changing out the all the parts of the fuel system, I'm still getting high pressure fuel code errors, I'm losing power between 2K-3K, along with the squeal at the same time - I'm not sure where to look next?


Anyone with thoughts?

A diagnostic print out would be a good place to start chap, vcds is allways good .
some real time logging and error logs will help start making progress towards resolving issues .
It will just be taking pot luck diags otherwise.

maybe wise to check the waste gate acctuator etc for correct function, they are prone to problems of over and under boost.

 

[bunnyfunk]

Thanks Rob - Is vcds easy to get hold of?

It's a squealing sound which gets me. Could a boost leak cause this sound?

 

[Charlie Farley]

did your mechanic check the condition of the cam lobe , normally when the cam follower wear through the hpfp shaft runs on the cam lobe and makes a right old mess.

 

[Charlie Farley]

Thanks Rob - Is vcds easy to get hold of?

I'm biased towards vcds but there are other diag programs on the market.

A good one will tell you a lot on how your car is running in realtime and if there are any things amiss.
if you havent used vcds or similar before then maybe a better plan to get someone local to you that knows the software to do a good scan .

 

[Charlie Farley]

Thanks Rob - Is vcds easy to get hold of?

If you are hearing that sound at the same sort of rpm range that the boost appears to drop off then it is highly likely the two are connected, possibly a boost leak in the system , check all hoses for leaks , also the wastegate / accuator for correct operation .
high piched squeling can be a pressure leak , vcds will show up so much if the person running the scan knows how to use the program.

 

[bunnyfunk]

did your mechanic check the condition of the cam lobe , normally when the cam follower wear through the hpfp shaft runs on the cam lobe and makes a right old mess.

We both checked the cam lobe and it looked fine.
One other error which is showing up is the timing. Wondering if the front belt timing is off, would this cause issues with fueling?

 

[bunnyfunk]

Thanks Rob -

Sounds silly, but I've tried looking for the wastegate but can't seem to spot it, could you point me in the rough direction?

 

[Charlie Farley]

you can't see the wastegate itself from the ouside only the shaft and linkage as it is inside the turbo housing but you can see the linkage between it and the actuator.

 

[Charlie Farley]

Also its all on the underside so you need to look from below.

 

[Charlie Farley]

We both checked the cam lobe and it looked fine.
One other error which is showing up is the timing. Wondering if the front belt timing is off, would this cause issues with fueling?

If you have a lot of excessive wear and play in the rear timing chain etc the timing can become an issue, also if the tensioner is worn or not working correctly due to lack of oil pressure etc, rear timing chain adjustment is very important on these engines.

 

[Charlie Farley]

 

[Charlie Farley]

Cam belt controls the intake cam, cam chain connects the intake cam the vvt variator and exhaust cam, but everything needs to be spot on front and back, the variator controls the VVT .
Once you get excessive play in the cam chain for whatever reason things get out of adjustment very quickly and worse.

[bunnyfunk]

Thanks Rob - appreciate the detailed response!

I'm thinking this is turning into project car time - yay!
Well I suppose this will keep me busy if we're going back into lockdown.

Will probably start with the front timing and work my way forward from there... after I'm run proper diagnostics on the car!

...and that's without dealing with flickering main beam headlight

 

[Charlie Farley]

Running vcds or similar should be your next step to be honest, it will help identify problem areas and help you address more specific faults code items.
A good scan will get you a lot of info on realtime data which will be really helpful , such things as requested and actaul comparisons on fuelling , boost etc.

It's to easy to just keep double guessing problems and buying parts and not resolving the core of the problem, decent diagnostics are the best way forward really chap.

best of luck with it.

 

[Sidrick]

If it were me, I'd be measuring the lobe on the intake cam. It's the right age to have had a chocolate one fitted and if it's worn through the follower then I can't see how it's possible that it's not damaged.

Flickering main beam are likely the Xenon Bulbs. Just after replacing mine.

One was on the blink....

Sorted it. And 10x better than 12year old bulbs. Brightness is fantastic. Best money I've spent on the car

Osram D1S bulbs

 

[bunnyfunk]

Thanks Chaps -

Cable ordered - diagnostics first. I hear ya

@Sidrick - I'm assuming that would be a new set of cams?

@tr7 - Thanks bud, will give those a go!

Yes to the Xenons, no to the auto lights

I agree the clear indicator makes it look more modern lol.......

TBH I'm not sure I like the way you've styled the motor, something just doesn't look right

Ouch, hope you're ok fella!

 

[Charlie Farley]

That's only a light scuff, a bit of t-cut and some filler and you'll never notice it..

Best money I've spent. Find myself wanting to go for a night drive just because they're awesome

 

[Pie-eyedpiper]

Are they a straight bulb swap?
