C2 Smoke on Acceleration

Hey, I also have a C2, though not sure about the year model right now. I had something similar a while back. Was the smoke blackish? And did it feel like the car was struggling a bit when accelerating?

Yes, the smoke is blackish, and it does feel like it's struggling. Was it also the exhaust back pressure sensor in your case? What did you do about it?

Well, it sounds pretty similar. Honestly, I'm no expert, but the symptoms seem like what I experienced. I just took it to a workshop and they sorted it out. They told me it was the sensor. Better get it checked properly.

Okay, thanks for the info. I'll take it to a workshop. Turns out you were right. It was the exhaust back pressure sensor. Cost me 245€ to replace.
