Seat Leon electric steering column issue

I had a similar electric steering problem with my BMW 3 Series a while ago. The error memory also showed a fault, and the steering column wouldn't adjust. Have you checked the relevant fuses and relays? Sometimes it's a simple fix before diving into more complex diagnostics. In my case, it wasn't the fuse, but the control module. Was the mechanical fault of the steering ruled out?

Interesting. You mentioned a defective control module. Was that diagnosed via error codes, or was there some other way to pinpoint it? I'm wondering if the Leon's issue could be similar. Did you also get the 'cable or plug connection defective' hint?

The error codes pointed towards the steering column module, but further diagnosis revealed it was a faulty connection. Before replacing any expensive components, I recommend having the wiring thoroughly checked by a qualified technician. A simple continuity test can often identify the culprit. If the wiring checks out, then a faulty module becomes more probable, and you should visit the workshop.

It was indeed a defective plug connection, just like you suspected. 95€ later, the adjustment issue is resolved. Thanks a lot for your help!
