Adam power steering vibration

I had a similar issue with my Adam. Vibrating steering, increased effort... Sounds familiar. Did you check the cable and plug connections to the power steering component? That was the culprit in my case.

Which specific cable and plug connections should I be inspecting? Are these readily accessible, or do I need to remove any components to gain access?

I'm not a mechanic, so I cannot provide specific details, but I advise you to check these connections. I had the same symptoms with the electric steering, and the mechanic confirmed the defective connection. I would recommend visiting a workshop for a proper diagnosis. It could save you a lot of time and potential further damage.

Based on your suggestion, I took my Adam to a local workshop. They confirmed it was indeed a defective cable or plug connection as you suggested. The repair cost me approximately 95€. Your advice was invaluable!
