Seat Mii Engine Mount Issue

I'm having a strange issue with my 2018 Seat Mii with a gasoline engine. It has 95278 km on the clock. I've got an error stored in the error memory, and the engine is idling unevenly. I suspect it might be related to the engine mount. I've read that a likely cause could be a defective cable or plug connection. Has anyone experienced similar engine mount wear?

A 2018 Seat Mii with 95,278 km was experiencing uneven idling and an error code, suspected to be related to the engine mount. A possible cause mentioned was a defective cable or plug connection. It was suggested to check the wiring and plug connection for corrosion or damage. Ultimately, the issue was resolved by replacing the defective engine mount, which eliminated the error code and smoothed the idling.

Uneven idling and an error code definitely sounds like it could be a motor mount issue. I had something similar with my Mii, though it wasn't the mount itself, but a corroded connector to a sensor on the mount. Have you checked the wiring and plug connection to the engine mount? Sometimes a bit of cleaning and contact spray can do the trick.

Interesting, you mention the wiring. Where exactly is the plug connection located on the engine mount? Is it easy to access, or do I need to remove other parts to get to it?

On mine, it was on the right side, near the top of the engine mount - fairly easy to see once you know where to look. But if the mount itself is damaged or worn, it's best to get it checked by a professional. A worn engine mount can cause vibrations and stress other components. So probably you should go to the workshop.

Took it to the local garage, and it turned out to be a defective engine mount as suspected. They replaced the mounting bracket, and the error code is gone, and the idling is smooth again. Cost me 95€, which is what I expected. Thanks for your help!
