Tiida Power Steering Vibration

I have a Tiida as well, and that sounds awfully familiar. I had similar symptoms, especially the vibrating steering wheel and the increased effort needed to steer. Have you checked the power steering fluid level?

Yep, fluid level is fine. I was reading online that a defective cable or plug connection could be the culprit? Did you find out what the problem was in your case?

I didn't want to risk damaging anything further so I took my car to a workshop. After inspection, they confirmed a faulty electrical connection to the power steering system. The error memory also indicated the same. I advise doing the same for your own safety.

Thanks for the advice! I bit the bullet and took it to a workshop. Turns out it was a defective cable connection, just as suspected. Cost me 95€ to fix. Appreciate the help!
