RCZ Power Steering Issue

I had similar symptoms in my previous car, though it wasn't a Peugeot. Have you checked the power steering fluid level? Also, are there any unusual noises coming from the steering pump when you turn the wheel? Maybe it's a pressure hose issue?

Fluid level is fine. No strange noises from the pump, though. Where exactly should I be looking for pressure hose issues? Is there a common point of failure?

Without physically seeing it, it's hard to say exactly. I'd start by checking the connections to the pump and the steering rack. Given the error and your symptoms, it's probably best to get it checked by a workshop.

Thanks for the advice. Took it to a shop, and you were right - it was a bad connection. 95€ later, all good.
