C30 reduced engine power

I had a similar issue with my Volvo C30. Reduced power and the check engine light. Have you checked the accelerator pedal module or the electronics inside? That was the culprit in my case. It could also be the throttle sensor.

Thanks for the quick reply. You mentioned the accelerator pedal module. Was the replacement costly, and did it solve the problem completely? Was your fuel efficiency also affected?

Yes, replacing the accelerator pedal module completely solved the issue. I was also getting pretty bad fuel efficiency. I went to the workshop and the replacement cost me around 265€. It's worth getting it checked out.

Thanks for confirming. I'll take it to the workshop to get the accelerator pedal module checked. Hopefully, it's a straightforward fix like yours. Appreciate the help!
