Hello, I had a similar problem with my 2006 Citroen C4. My control unit was defective. This caused symptoms similar to what you are describing. First I noticed a vibration from the steering wheel and then the problems with the steering started. After a while, there were also problems with the ABS. Got it exactly as you suspected. At my garage they said it was the control unit. After replacing it, everything worked perfectly again. So it was quite easy to fix, although it was quite scary when it first happened. It's not a small thing, but it's not a disaster either, so don't panic. I've been through other things with the same mechanic, so have it looked at. Best regards!

Hello, thank you for your feedback! It's reassuring to hear that your problem could be solved in the end. Do you remember roughly how much you had to pay for the repair? And has anything else come up regarding the problem since then? Many thanks in advance! Best regards!

Hi, you're welcome! I had to pay around €415 to repair the faulty control unit, but I thought that was perfectly reasonable once everything was back on track. And in answer to your second question, I can only say that since the visit to the mechanic, the signal error in the electric power steering has disappeared from the face of the earth. I haven't had any more problems. I hope that makes things a little easier for you. Take care!

Hello, that's definitely a relief! 415€ is a fair price if everything works properly again afterwards. You've helped me a lot, thank you again! I will now follow your advice and visit the workshop. Wish me luck! See you soon and take care!

Hi there! Sorry to hear about your Berlingo troubles. I have had the exact same issues, but checking the power steering sensors and connections might help. Has anyone else experienced similar issues?

Before you visit the workshop, you could try checking the power steering sensors and connections as CarFreak suggested. It's a simple check that you can do yourself and it might save you a trip to the mechanic. However, if you're not comfortable doing this, it's best to let a professional handle it.
