Summary of the thread
A 2012 VW Polo Diesel with high mileage is experiencing issues such as the check engine light being on, engine stalling, rough running, jerking during acceleration, and starting difficulties. These symptoms may be related to the fuel pump, potentially due to incorrect software values affecting its operation. A suggested solution is to have the vehicle's software updated, as this has resolved similar issues in other vehicles without requiring mechanical repairs.

Hey, thanks for the tip with the software! I'll keep that in mind. I hope it's nothing mechanical with my Polo either. Can you remember how expensive the software update was for you and whether you've had any other problems with your Golf since then? Thank you and best regards!

Hey, after your questions, I can tell you that the software update for my fuel pump only cost around €45. So it was absolutely affordable and definitely helped to fix the fuel pump defect. Since then, my Golf has been running like the first day again, so I haven't had any more problems. So, cheer up! Many things can be solved by software updates like this, just give it a try and let me know how it goes for you. Best regards!

Hey, you've really helped me out. That sounds like a very cost-effective and efficient solution. So I will definitely ask my new garage for a software update for the fuel pump and then hope that my little Polo will run smoothly again. I'll keep you posted on whether it works. Thanks again and see you soon!

Hi, I had similar symptoms with my 2015 VW Golf Diesel. In my vehicle, it turned out that incorrect software values for the fuel pump were the problem. It had a strong influence on the functioning of the engine. I kept having problems during cold starts and when accelerating, just as you describe. The garage eventually updated the software. So it was quite serious, but fortunately not a mechanical failure, which would have been more difficult and time-consuming to fix. Always make sure your vehicle is serviced regularly and have the software checked if you have similar symptoms. Maybe that will help you! Best regards!
