Safrane reduced engine power ECU issue

My 1999 Renault Safrane with a gasoline engine has reduced engine power and a persistent fault code. Mileage is at 135221 km. I suspect previous chip tuning. Any ideas?

Sounds familiar! I had a similar issue in my Safrane. Was like driving through molasses! Did the diagnostic code point to anything specific? The car computer can be a real drama queen.

It was a generic code related to the ECU. Any ideas what fixed it for you? Was it an expensive fix?

ECU, huh? Sounds exactly like what I went through. It turned out the previous owner had messed with the chip. Take it to a workshop. They can diagnose it properly and re-flash the ECU.

Took it to a shop, and you were spot on – dodgy chip tuning. They re-flashed the ECU, and she's purring again. Cost me 180€ all in.
