Does anyone know what this problem could be, after going on a fairly long drive in my mothers panda and coming upto a round about the power steering just went completely stiff , it was almost impossible to turn the car, after pulling over I checking the fluid and belts and they were all fine, started the car up again and the power steering was fine again, my mother has said it's happened to her a few times, it's a bit dangerous can any one help please
Just had same issue, luckily I have access to
MES/cantiecar diagnostics and can read the info, mine was a voltage low warning as the main indicator,
Also worth checking for these kinds of fault - (definition of that - loss of steering, wheel red light on, cures on restart, no difference on power to either side when working or under fault, no unusual noises, no pulling to left or right)
Definitely battery, also check the ground (body) connectors - there are several - many in fact ! located around and with the steering. ANY one could cause this kind of fault.
If you feel comfortable enough, disconnect power, wait 10 mins, remove connectors from EPS unit, torque sensor, motor, ecu etc, spray with contact cleaner (NOT ! WD40 etc) and replace.
More than like sort the issue.
Most EPS faults are very minor, that is why the multitude of repair places charge so little and include delivery and collection. I am convinced that most times it is a simple clean up of connectors as all they need to do.
Also, to add, the reason the steering goes so heavy is that the rack used on the eps models is only 2 point something turns lock to lock, the non eps were 4 point something.. DEFINITELY check tyre pressures also as low pressures and a roundabout can signal a high current trip.
