Laguna uneven idling engine mount issue

I had something similar with my Laguna (probably same engine). Uneven idling drove me nuts. Check the rubber mount itself, not just the electrics. Mine was totally knackered, like, properly failed. Is it worn out?

When you say 'knackered,' could you elaborate on what you observed? Was it visibly damaged, or did you notice excessive movement in the engine?

Right, 'knackered' means the rubber was split, basically falling apart. Engine had way too much movement. Honestly, I'd get it checked out at a workshop, sounds like a failed mount is causing your issues. Cost me around 95€ to replace but could save you some serious grief down the line.

I appreciate your advice. It does seem prudent to have it professionally inspected. I have scheduled an appointment with a local workshop to assess the engine mount and address the uneven idling. Cost me the amount of 95€. Thank you again for confirming my suspicions.
