Steve Q

Please could you supply a picture of the led, that way we can tell if it's aftermarket or not.

I feel your pain, as it's the same situation with Audi's from the 90s/noughties like my A6. I agree it's due to the wef agenda. Eu looking at banning garages from doing major repairs to old cars like engine changes/rebuilds etc so they can get them off the road. I need a replacement engine in my A6 and think I've finally found a way to get another one fitted. But long term the only way old cars will remain in the road is to use engines etc from cars with huge parts supplies like Chevy ls motors for example.

Any fault codes?

I'd recommend seeing if it needs a software update and speak to Audi.

Speaking from someone owning a similar aged A6 it's electrical gremlins and issues with imobilisers. My engine has gone bang, and trying to get the car back on the road is proving a nightmare. Engines and engine parts are getting in short supply etc.

Let's not forget we also had a pandemic in 2020 which shut most of Europe.

I'd recommend you get a second opinion.

Nope they won't be compatible due to widths of the car.

Thanks Steve. It's just so confusing when those on A6 C5 Facebook groups give mixed information. I did find this engine which I'm debating to take a pint on. It turns freely but has no history. https://www.ebay.co.uk/itm/386915243941?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=iasddtvhsyq&sssrc=4429486&ssuid=IE07kO4STZy&var=&widget_ver=artemis&media=WHATS_APP If this is a genuine option then I wonder where a later bau or Ake engine (both 180bhp) would be a better option as they'll be detuned due to my ECU.

Hello all, my mechanic believes that if I keep my ECU and injectors and put it in a 2.5tdi that has different engine code then the car should work fine as the imobiliser/ECU will think it's the old engine. I know the Ake and bau are different heads but would the 150bhp and 163bhp engines have the similar design to aym. As such would this work just adding my ECU and injectors to the different engine code. Then I wouldn't needs to code the pump ect. Would it also work for bau or Ake even though heads are different? Just want full clarity before I buy any engine as I'm still under the impression the injection pump, instrument cluster and ECU have to match. I'm tearing my hair out now as I just want the A6 back running so any help will be appreciated.

I'd recommend you speak to autologics or Audi retrofits. You'll need it coding.

I wonder if the mobile phone film type would work?

If it's that easy why hasn't he done it? I'd recommend a second opinion, preferably from a mobile mechanic, ideally one that's vag knowledgeable.

I'd recommend getting this back to the garage who did the work for them to rectify it.

Dpf might need replacing if the cleaning doesn't work. Regarding the power steering, how old is the car battery? I ask because if it's over 5-7 years old then it could be failing. This can cause the car to throw up all sorts of electrical issues.

Unless the power steering emis whining etc id say it's normal compared to new cars.

Loving those wheels 👍

Very nice 🙂

No probs, please keep us posted on how you get on

I'd recommend a diagnostic check to see if any fault codes flag up.

Could well be. Plus the fact the A4 is bigger will keep it more planted.

Thanks for the heads up. Glad you got it sorted.
