Peugeot 407 Engine Mount Issue

I'm having trouble with my 2008 Peugeot 407 (gasoline engine). The engine mount seems defective. I'm getting an error and the engine is idling unevenly. I think it might be the cable or plug connection. Mileage is at 131834 km. Has anyone seen this before?

I had a similar issue with my 407. The error code pointed to the mount, but the problem was intermittent at first. Did you check the mount for wear or damage? Sometimes it's obvious, sometimes not. Is the uneven idling constant, or does it fluctuate?

Thanks. The mount doesn't show obvious wear, but there's some play when I move the engine by hand. The idling does fluctuate, more when the engine is cold. Do you remember any specific error codes you were seeing?

My experience is the same; visible wear wasn't obvious right away. The error code was about engine mount performance, I think. With the fluctuating idle and play, I'd get it checked at a workshop. I replaced mine – cost about 95€. Better safe than sorry, especially if the mount fails.

Thanks, I'll book an appointment with my mechanic to check it. Your experience confirms what I thought, and I don't want to risk more damage. Thanks again!
