Talisman Diesel Engine Power Loss

I had a similar issue with my Talisman. It turned out to be a faulty chip tuning, done by some third-party providers. The diagnostic code pointed towards an issue with the engine's performance parameters being out of range. Was any aftermarket tuning done on your car?

Thank you for your reply. Now that you mention it, the previous owner did mention something about chip tuning. Could this really be the cause, and how did you resolve it?

Yes, in my case, the chip tuning was definitely the culprit. These aftermarket modifications can sometimes cause more harm than good, especially if they're not done correctly. I ended up taking my car to a reputable workshop to have the ECU remapped to the original factory settings. It might be worth considering a similar approach.

Thank you for the advice. I followed your suggestion and took the car to a workshop. They confirmed it was indeed a faulty chip tuning causing the issue. They reverted the ECU to the original settings, and the engine power is back to normal. The repair cost me 180€ Appreciate your help!
