Peugeot 206 stiff steering and vibration

I had a similar problem with my Peugeot 206. Does it happen especially at low speeds, like when parking? If so, it could be related to the steering angle sensor. Is your car equipped with ESP?

Yes, it's worse at low speeds. And yes, it has ESP. What exactly is the issue with the steering angle sensor?

From what I understand, the coding of the steering angle sensor can sometimes get messed up. This can cause the problems you're describing, as it interferes with the electronic stability program. If it is that, I would recommend taking it to a workshop to have it checked. In my case the sensor replacement cost me 195€.

Thanks for the help! I'll take it to a workshop and mention the steering angle sensor. Hopefully, that's the issue. That sounds like it might be it.
