Peugeot 107 rough idling

My 2013 Peugeot 107 diesel with 109315 km is idling rough, and I've got an error code. My mechanic thinks it's the engine mount, likely a dodgy cable or plug, and quoted 95€ for the fix. Does that sound right? Anyone else had engine mount issues on these?

I had a similar issue with my 107. Check the transmission mount as well. A failed mount can cause vibrations and throw off the engine's balance, potentially leading to that error code. Have you checked the rubber mount for wear and tear?

Thanks for the tip! I hadn't considered the transmission mount. When you say 'similar issue,' was it also rough idling and an error code, or something else? How did you diagnose the transmission mount? Is it easy to spot the wear?

Yes, I had rough idling and a stored error, very similar. Diagnosing the transmission mount wear can be tricky without a good inspection. Look for excessive play or cracks in the rubber. If you're not confident, it might be worth having a workshop take a look. They'll have the proper tools and experience to assess the mounts accurately.

Appreciate the advice! I took it to the shop, and you were spot on – it was indeed the engine mount! They replaced it for 95€ as initially quoted, and the idling is now smooth. Thanks again for pointing me in the right direction and suggesting the workshop inspection!
