My sunroof is knackered! It was leaking and now it just does not open. I geuss the electrics have got wet. Is this a pain in the arse to sort? Also there seem to be grooves in the bodywork on all four corners of the sunroof. Is this the norm cause is saw another valver with same grooves. Or is it just a flimsy roof that easily dents. It looks like someone has jumped up and down on the sunroof. Also i have got an oil leak! if its not from the oil filter or sump bolt what could it be? Cheers if anyone could help
