Imobilisers

[Steve Q]

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.

Hi Steve your mechanic is correct, due to Audis practise of using the same engine but putting different emissions gear on them and giving the engine a different designation you are almost certain to be successful as the basic block will be the same as will the heads, if you look at the engines for my A6 CNHA most of the parts were common to the DETA,DDDA,same engine different horsepower which is controlled by the ECU, ergo unless the engine has a mind of its own it will wait for the ECU to tell it what to do.

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.

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.

Hi Steve, I personally would not go anywhere near that one it looks like cheap trouble until you get the bill for the rebuild, go for a later engine thats got some history and runs, not some vague statement that it did and then spent an indeterminate time in storage, no milage, I think he wants to go to the pub on someones £80, I have made the same mistake in the past especially when driven by desperation, take your time send your cash wisely and make sure what goes in at least works.

Thanks Steve, think I'm looking at the last of the line bau version. I've found this refurbished one in Germany, and I've messaged them with a few questions regarding the turbo etc.

Hi Steve that looks the better option, ask for a comprehensive list of what's been refurbished, yes its a lot more money but it will at least give you a solid platform to build on.

Exactly. I had to translate it in Google and it's had a full refresh.  I've asked if they ship to the UK. Not heard back yet but it's the weekend. To show the comparison in price, they have a used aym versions with 87k miles and its €300 less.
