Skoda Kamiq power steering issue

That vibrating steering wheel and spongy handling definitely point towards a power steering issue. The error code seals it. With that mileage, a cable or plug connection could be the problem, like you suspect. Before diving into the steering system, have you checked the power steering fluid level? Is the power steering pump making any unusual noises? A failing pump can sometimes act like this. When you mention error memory, are you referring to a specific diagnostic trouble code? Knowing the code would help narrow things down. Wheel alignment could contribute to steering issues, but it typically wouldn't cause the power steering to fail entirely, especially not with a stored error. Let me know about the fluid level, pump noise, and DTC, and we can explore this further.

Thanks for the quick response! The fluid level is fine, and I don't hear any strange noises from the pump. The DTC is C10AD07. Does that tell you anything more?

Okay, DTC C10AD07 confirms an electrical fault in the power steering control circuit. Since the fluid level and pump seem fine, it strongly suggests a wiring or connection problem, precisely as you initially suspected. While it's great you're proactive, a wheel alignment won't resolve this electrical issue; it's a separate concern. Given your description and the DTC, I highly recommend getting it checked by a workshop. They'll be able to properly diagnose the wiring harness and connectors related to the power steering system. Trying to fix this yourself without the proper diagnostic tools and wiring diagrams could potentially cause more damage to the steering system. It's likely a relatively inexpensive fix, hopefully just cleaning or replacing a connector, but it's best left to professionals with the correct equipment.

You were right. It was a bad plug connection. The workshop charged 95€, including finding the problem. Thanks for the help.
