I will drive the car tomorrow myself to see if it is just a dash light or if the system has failed.
Hi Lifeforms
The steering went much lighter at low speed.
Once up to speed, the steering felt normal again with decreased assistance, although the light stays on.
I switched it off at around 40mph and didn't notice any change in steering feel.
I can see how it would be useful to the elderly (on the 1.2 at least). Is your father able to drive the car with the power steering on its normal setting?
If the city light doesn't come on, but the steering becomes lighter then it's just a bulb.
If not then my first test would be to run a jump lead from battery negative terminal to engine block to test if the earth lead is the culprit. If still no change, I would then try a different battery. After this, a sparky could test the switch for you.
There's a list of MultiECUScan users here who might be able to help you diagnose the problem if the above steps don't help. Best of luck
