Seat Alhambra Diesel Uneven Idle

Uneven idling and error codes can be a real headache. I had a similar issue with my Skoda Octavia a while back. It turned out to be a failed transmission mount. Did you check the rubber mount itself for cracks or damage? A failed mount can definitely cause vibration and trigger error codes.

Thanks for the reply. You mentioned checking the rubber mount. Is this something easily visible, or would I need to remove the mounting bracket to inspect it properly?

In my case, the cracks were quite obvious once the mounting bracket was removed. However, I'd recommend having a workshop take a look. They'll be able to properly diagnose the issue and check for any other potential problems with the mounting bracket or other associated components.

The workshop confirmed the defective engine mount. They suspect a faulty connection as the cause. Repair will cost approximately 95€. Thank you for the assistance.
