A3 1.9TDi 2007 - Blown Engine

Just change the big end upper bearings and frequent oil changes .

I get my oil changed every year or 7k miles because I don't really rack up too much mileage a year. The big end up bearings expensive to change?
 
Very yummy but doable ?

Get a 2nd hand 1.9 engine and just rebuild with better parts .
 
Rod Porn :) haha ive got a phone full of it lol

OK the BKC and BXE is a straight swap, BUT the engine mount was changed in 2007, so on the early one the mount goes through the cambelt cover, the later one it bolts above the Alternator, everything else is the same

Actually it isnt, BXE have a different oil filter top, the threads are different, but thats nothing to worry about as you wont need to swap that :)

6 hrs to take one out, swap all the bits over and refit, ive done that many now lol
 
No problem bud, blunt is not blunt, it's honest and that's what I want

So guys if the value of this car is less than £2,000 and others are indeed available for less than £1500, then we should reconsider and buy a donor for an engine instead?

Phil is the BKC engine you suggested a straight swap into this model?


Jim find a replacement engine and contact me :)

Can you fit a tea break in there Phil? That's good going mate, would take me 6 days.

At least you can do it in 6 days, I'd stare at it for 6 years, because that's the most I'd be able to do to it

haha, i just take the front end off, its then easy, ive found that the quickest way, once out and the box and bits swapped over it goes back together within a couple hours
 
But ideally on a 2nd hand engine renew upper bearings and ultimately renew rods with better ones as your pic Phil.

How much extra is bearings and rods ?

IIRC the rods were £200, bigend bearings were £65 and rings were £60, worth doing imho

Rachels A3 was the first time id seen rods fail on the PD and stupidly replaced with a BXE, yet when i had to replace my Passat BXE i found a BKC and fitted that

My mk5 Golf was a BKC and i owned it 6 yrs and it had 200K and was faultless

Everyone needs to move close to Launceston i can spend my days fitting forged rods in 1.9s :)
 
BKC are even rarer to throw a rod but not immune .
Gazwould - you have just removed all traces of Audi AND VW from my bloodstream!

And from that of all my successors until Armageddon, Apocalypse, End of Days, The Earth Stood Still, The Fat Lady Sang Already, and beyond!

Brrrrr!!!! Creeeepy!!

We'll be sticking to Ford, Jaguar, Merc Toyota, Nissan, and Mazda from now on! Maybe Alfa Romeo isn't so bad after this?!! :)

Phil - Thanks for your guidance, which engine would you prefer, (or which is the most common), and from what cars?, as I would follow your advice to renew the conrods and bearings etc before installing?

Ok as you will have the rods and bigends replaced a BXE wont be a problem, and that can come from A3 8P mk5 Golf, B6 Passat, Seat Leon, Skoda Octavia, mileage isnt a worry as the rebuild will make it as good (actually better) than new :)
 
For a side-chat while we're jovially gathered here together chewing over my problem, to some plan of action...

My S Type 2.5-litre V6 produces 200bhp flat. The 3.0-litre produces another 25 bhp I think, the standard 4.2-litre V8 without Turbo produces 300bhp.

How on earth did anyone get 300bhp out of a 1.9TDi??? Was that in an A3?

Haha, ok, to get 300bhp from a 1.9, you would need a Hybrid turbo (Xman £800) a perion intercooler or S3 cooler (all alloy) as a min, the major problem will be fueling, ARL injectors will never flow enough to feed 300bhp, darkside can supply the injectors but there not cheap, then you will need a clutch and flywheel combo to handle the torque

Thanks Phil. I'll see what I can find.

Can you drop me a message with approximate cost of the whole refurb and engine change please?

Oooooo...

Now you gots me thinkin'!!

If we could raise it to... say... somewhere around what? 220-250bhp...? <evil grin>!!

We could then paint fire decals on the sides, and then we could very well ask... what? £6k? £8k?? £10k???

Whaddayathink, Pardner? Is it feasibubble? :)

Wasn't that the pd130 that reached 300bhp or was that the 105?

Ive heard of a few 105 mk5 golfs running 280-300 figures, my first thought was always what its like as a daily

TBH 200bhp from a 105 is a very quick car and is very easy to reach that figure as ARL injectors will flow that, only Hybrid needed and decent boost hoses

Yes I've heard the same, a hybrid turbo, sports clutch and apparently the standard injectors can flow up to 200hp with a decent map. But tbh the 105 is known for its economy so personally I wouldn't mod it so much.

I agree Phil, super tuned engines aren't often friendly.

Years ago we couldn't get this kind of terrastic power increase but were always trying and tuned cars fetched over the top prices even in shabby condition.

What's a typical price if we upgraded this particular car to 200bhp?
 
The 300bhp 1.9 car I'm thinking of is in a Skoda Fabia, is actually a PD100bhp version. Yes it does have a big turbo and other parts that Phil describes.

ATD code, almost the same as the BXE/BKC same 50mm bigends, the ATD block needs slight changes for use as a BXE, namely the crank sensor and a plate made to use the A3/mk5 golf oil filter housing
 
Hello chaps. Just to update you, since I don't like leaving threads open ended.

The car did sell, and for near to the price I expected.

So you can revise your expectations, £1100-1300 is far too optimistic, or maybe too pessimistic, depending how you look at it.

Engines are available for around £450-550 and that is what the chap who bought it is going to do, so he'll get this A3 on the road for a single day's work, and for at least £1,500 less than its average value. Makes good business sense to me too.

I did give you chaps first refusal ;)

Thanks all for a great response, a very interesting pipe-dream discussion about performance upgrades, and keep up the great welcome to newbies.

I've been on many other forums which need improving, I can tell you ;)

All the best, guys. Thanks again.

Good job you sold it, however buying 2nd hand engines is pot luck, you can spend a whole week trying to fix a duff engine or you can strike lucky and get a good one first time !

Aye, I agree. The chap seemed to know what he's about with it.

If we had decided to rebuild it I would have taken your advice and refurbished it anyway. I did that with many an engine in my mis-spent youth, including a Zephyr 6, several Cortinas, an original Mini, and a Sunbeam Rapier. Have fun looking them up. ;)

But I'm getting on a bit. ;)

Thanks again guys, all the best.

And thanks to you too Phil.

Is Phil alive? Lol I've been trying to get a hold of him for nearly 3 weeks. I bought some fogs off him but still waiting lol :/

I think he must have had heart failure when I told him we'd sold our A3 for more than he offered! ;)

Phil where are you?

Hi chaps,

SInce you have been so helpful I had to come back to give a warning to diesel owners with DPFs = Destruction Preset Fuses.

This problem was most probably due to diesel fuel being forced into the sump past the piston rings during a DPF regen cycle, despite the long journeys at motorway speeds on a daily basis which should have eliminated the need for any regen cycle.

I am surprised now that nobody here mentioned this as a possibility and instead accepted it as a known BXE engine problem.

It is well known in other forums, including the Jaguar diesels, and there are thousands of occurences to owners who do not understand or know of this problem and just suffer engine damage and loss of their cars due to short journeys and incomplete regen cycles.

There is a DPF back-pressure sensor in some cars (e.g. Mercs) and that is used to trigger a regen cycle if the DPF is sensed to be partially blocked, as well as an EMS calculation on distance and perhaps time and average speeds the car is undergoing which is also used to trigger the regen. I think our car responded to the latter..

It's not a case of changing oil more frequently, the manufacturer has a long history of being meticulous and always playing on the safe side, there is little to be gained and much to be lost by dealers in extending oil change intervals to 20k. And putting the marque's reputation at risk is no light matter.

Check out DPFs and regen cycles and diesel in the engine oil, there are litterally thousands of cases of engine failure ewvery year - big end knocks, seized conrods.

Once the deed is done the weakest point will break, sometimes the bearing and sometimes the conrod big end, like ours. In the BXE it seems to favour breaking the conrod and spitting it out, rather than knocking big end bearings.

So it's chicken or egg, but the result is - the same, a killed engine.

In blind trust, we hadn't checked the oil level to see it had risen... and after the event... there WAS no oil! ;)

References:

Gut those DPFs while you can still get away with it and delete the regen cycles.

Best regards,

Jim
