Just in case it becomes a regular occurance ill let you know, went to get in the car this morning and noticed something hanging down by the wheel. Had a look and it turns out its the front part of the wheel arch lining, that then extends out to the front bumper. looks like it came loose and then started rubbing on the wheel and ground. shoved it up behind a bit of engine and went to see ever so professional Reno (irony b4 u start!).
guy had a look and tried to say it was my fault, told him very politely that if the wheel had thrown something up it would be at the back, if the front of the car had touched the road then there would be a scrape on the splitter. now getting done under warranty. he even hummed and harred about securing/removing what was left, until i told him it looked secure cos id wedged it in. dunno if he had even been looking at the right car when he went to have a look the muppet.
hope this is a one off
