Hi kristjan.
In my opinion you might have a problem in the encoder bearing of the electric motor.he doesnt send the signal to the controller and no error code is displayed.
It could be to the POT of the steering alignment.
Had a similar problem 2 months ago,replaced this POT and was ok.
This issue could "stuck"the wheel hardly or some times intermitent.
Hope it helps,best regards.
