Peugeot 308 Diesel Power Loss

Sounds familiar! I had a similar issue with my 308 diesel. Rough starting and a noticeable dip in power. Did you check the crankshaft sensor as well? Sometimes they play up together. Could be a dodgy connection, but those sensors can be real gremlins.

Thanks for the quick response. I didn't check the crankshaft sensor. Where is it located and is it hard to reach? Can I check the cable or plug myself?

I'm not a mechanic, so take this lightly. I fiddled around a bit, but space is tight, and without the right tools, you might make things worse. Probably best to let a workshop check the connections and replace the sensor if needed. My local garage sorted it out pretty quickly.

Appreciate your advice. I'll bring it to a workshop. Your comments confirm my suspicion. The repair cost was 95€, because it was just a defective plug. Thank you!
