I have lived with this problem for several weeks now. The warning light ignites when I start the car but goes out when I turn the steering wheel. It has happened on cold mornings and when the engine is warm. I commute 50 miles per day to work so I do not think it is the battery.

My dealer checked it (so they say) and said there was no fault shown as the fault goes away each time.

My next course of action was to disconnect the battery to reset the ECU, is there a specific terminal I should disconnect or does it not matter?

Many Thanks

imo disconnect earth first just for safety.

eamonnf,
Sorry is that the negative (black) lead?

Total car Biff coming through!!

That'll be the black one buddy, its only a safety thing really in case you touch the red one of the body of the car...

Thanks for the info mate, will try it on the weekend.

Have you got the battery drop tested?

Weak battery & cold morning starts take alot out of it and power steering is very sensitive to low voltage.
