my mate had a 04 clio and it stopped going up a hill in north wales on the a55,soon as a traffic car pulls in and officer dibble gets out,he has a quick chat and says he has seen clio's conk out before and it was the wiring going into the fuse box or ecu i can't remeber which lol so my mate has a wiggle and then they try the car and it fires dickey mint,they both look at the copper and he just smiles and waves them off.
