Oliver, yes that sounds familar, this is a shame having all these problems with the car as before I had this car I had an identical model C3 which unfortunately was written off in an accident (not my fauly I hasten to add) and to be honest it was a gem no problems at all in the 11 months I owned it, this one seems to be causing a few problems, if I get the gear selection problems sorted then its back to the screeching noise which seems to be coming from the front of the car usually comes after about 30-40 minutes being driven, hopefully will be problem free driving after that. One thing I must say about the C3 is that when I had the accident ( I was hit in the drivers side at about 40 mph, drivers door, rear door. back panel. the complete side demolished, it even bent the boot floor, a write off, I walked away from the car with some bad bruising ets on legs, safety wise it seems an excellent car.
