Starting difficulties with diesel Audi A6 from 2013: Possible immobilizer malfunction

Hi, I had a similar situation with my 2010 Audi A6, it had similar starting problems and it turned out to be quite serious. On my last visit to the garage, the mechanics found out it was an electronics problem, mainly with the starter motor. Seems like these models are prone to this. Also check that your air filter is working properly. You should probably have that checked next. Hope that helps you. Keep at it!

Hello, thanks for your advice! That sounds like a serious problem you had... Stupid question, but can you remember what you ended up having to pay for repairs? Since the repair, has anything else come up that you needed to have checked? Thanks for the support!

Hello, don't worry, it wasn't as bad as it sounds. After I went to the mechanic, the immobilizer malfunction was fixed. All in all, it cost me €45 because the programming of the key was faulty. Since then, the car has been running like clockwork and no further problems have arisen. Hopefully you'll get yours working just as smoothly, don't worry! All the best!

Great, that sounds like a good end! Thanks for the detailed information. I will definitely continue to keep an eye on my car and try to recognize such problems in good time. I just hope the bill won't be too salty. Your experience has given me courage. Thanks again! All the best to you too!
