Cheers TCB, tend to agree, daughter popped over with self firing windscreen wipers. They would start up on their own and then park in the middle of the screen.
Got the trusty WD40 out and sprayed that around. Turned out she had used a Jet Wash on it, I reckon it got water into the electronics somewhere. I went to a Renault Garage and after much sucking in of cheeks, "has it got a rain sensor", lots of head shaking. That could be expensive he said.
Anyway, used my trusted method, do nothing and let it all dry out. And its sorted itself out.
Think she will have to take it to Renteq, for the belts, least they know what they are doing.
