Audi A5 Diesel 2011: Engine problems and possible causes
(Translated from German)
Summary of the thread
A 2011 Audi A5 Diesel is experiencing several engine problems, including a check engine light, stalling, rough running, power loss, and starting difficulties. The suspected cause is a faulty fuel pump, potentially due to incorrect software values. A similar issue was resolved in another Audi by reprogramming the Engine Control Unit (ECC) and updating the software, which fixed the starting and running problems. It is advised to have the vehicle checked promptly to prevent further engine damage.

Hey, thanks for the quick reply. Your description gives me a better feeling. I hope it's just a software issue with my A5. Do you remember how much you paid for it at the garage? Have you noticed any other problems since then, or is your Audi still running smoothly?

Hey, I'm glad I could help! In my case, the repair in the workshop cost exactly €45 to correct the faulty software values of the fuel pump. And you know what? Since I had it done, my Audi has been running like a dream - no joke. The problem with the faulty fuel pump has been completely fixed. No more starting problems, nothing. Everything is tip-top! So I can only advise you not to wait too long and have it checked. Have a safe journey!

Cool, that sounds really encouraging! 45 is definitely affordable when it comes to getting my beloved Audi back in shape. I'll definitely take your advice and get this done as soon as possible. Thanks again! It's always good to know that you're not alone with such problems. I hope my Audi runs like a dream again afterwards. Have a good trip too!

Start by checking the fuse related to the monitor or infotainment system to ensure it's not blown. If the fuse is fine, try performing a reset of the system by disconnecting the car battery for a few minutes and then reconnecting it. If the issue persists, it might be a software glitch or a hardware fault, and you may need to consult a professional. Let me know how it goes or if you have any further questions!

Hey, it sounds like you're having similar issues to what I had with my 2014 Audi A3. It was actually incorrect software values for the fuel pump that made the engine run rough and caused my starting problems. At the workshop, they reprogrammed the ECC (Engine Control Unit) and updated the software values. This fixed the juddering and starting problems and the engine ran smoothly again. This was no small matter - without the correct software update, the situation could have worsened. If I were you, I would have it checked as soon as possible to avoid risking long-term damage to the engine. I hope this helps you a little. Have a safe journey!
