Great bit of advice there Stephen. Thanks for sharing 😊

There is an hydraulic pump. Have you done a diagnostic check?

I'm waiting on full confirmation on how bad it is. I'm finding it hard to find a specialist to work on it.

That's sods law! I'm refusing to give up on the girl. We've had her from new.

Its funny I thought about car sos! No way I'd qualify now. Partly the reason for the performance route was to rebuild a whole new engine excluding the bock as that avoids issues with DVLA. Plus with an expensive modified engine I'd go the agreed valuation route and this protecting the car slightly better from a write off situation. I've also weighed up that performance parts will cost no more overall than the stock genuine Audi parts where I can source them. That's my rationale. My brother thinks I should go the whole fig and Dona full resto as the engine is out anyway. All specialists I've contacted are shocked I've got 344k out of a no rebuilt 2.5.

Should be a straight forward job. I personally always get a qualified mechanic to do the work even though I understand the theory

It sure is. The A6 eats the suspension arms and bushes I find.

As audi have mis diagnosed it then there shouldn't be an additional charge for diagnosis in my opinion. I'd be getting it back to them.

I'd recommend looking at buyers guides on YouTube. Make sure it's been serviced correctly. Including relevant work on the Cambelt or Timing chain. Make sure all electrical items work

As it's a common issue I'd recommend getting it booked in at an Audi independent specialist.

Thanks both for your valid inputs. It's definitely a tough call. I've contacted a few garages, as my usual garage won't touch it. 2 others haven't got back to me a d darkside developments saud they don't touch the 2.5tdi. I'm going to contact the Audi independent specialist too. I'm very much of the opinion of getting her back on the road. Which leaves the following options: Find a donor and transfer everything over. My problem with a donor or 2nd engine nis that it just buys me time and doesn't secure the cars long term future. Rebuild current engine with either performance parts or stock. But in effect having a new engine other than block and heads. If I build a performance engine then I would upgrade brakes and suspension and then get an agreed valuation with insurance to make it harder for it to be written off. Or As engine is out do a full restoration. As other things like electrics need looking at anyway.

Been to the garage and heard the old girl running. There's knocking from the crank, and turbo is whistling/whining louder then it ever did before. The video says it all really. I'm in a predicament, repair engine, replace engine or scrap the car. Head says scrap, heart says rebuild. I've been doing research as finding knowledgeable people non the 2.5 is few and far between. I've sourced a second hand aym engine with 3 months warranty in Spain for £811 including postage. However the history on it is questionable. I've tried to source one in the UK without success. My garage where the car has been maintained for the last 18 years don't want to touch it for a rebuild. Darkside developments don't touch 2.5tdi engines, I've contacted another specialist who has got back to me. Going to try again today though.as I have more leads. From what I'm reading, besides the engine I might have to change the injection pump as that's coded to the car but the current one will only work on the lower horse power versions. I'd need the l pump if I fit a bau engine which has 180bhp as standard and seem more plentiful. The most extreme approach is to now build a performance 2.5tdi engine (stage 4) as it might be my only chance in life to get a highly modified car. As you can imagine I'm devastated and scrapping it isn't on the cards really. I just know once I start I'll end up doing more to it like changing the clutch and DML etc. VID20230405160344.mp4

Keep us posted on how you get on

Here's some guides: https://guides.brit.co/guides/audi-a4a5-bang-olufsen-subwoofer-upgrade

If you've bought it in the last 30 days take it back asap. In the 30 days after purchase you're entitled to a full refund or for them to fix it FOC.

eBay for aftermarket. OEM yiu might need to look at Europe as black editions in Europe got black badges but we didn't in the UK.

Thanks for sharing Steve. Think the bushes are a week spot on all A6 models. I know the bushes go in the arms of the c5 too.

Glad you found the parts. Did you manage to order one?

If you have one it should be in the compartment of the rear seat centre armrest

What's the service history on it? My dad has bad luck with an 8v 1.6tdi. His blew a turbo and then blew an engine all under 30k miles

This video might help: https://youtu.be/LwwcoIG4ci0

I'd recommend a diagnostic check to see if any fault codes flag up. Could it be maf, crank sensor, cam sensor?

Glad you got sorted 🙂

No probs at all. If there's too much power going through the wiring it could mean an issue elsewhere. I had a similar issue with my much older a6
