Don't remind me.
In my boy racer days I had an early Corsa GSi 16v which sheared its cambelt pulley on the M62 and lunched the whole engine.
Eventually Vauxhall swapped the whole car for another one, and that needed a new EGR valve every 3 months. At least I could turn up at the dealers and tell them what was wrong with it!!
As I understood it it was like a flap in the exhaust pipe which under a light throttle directed some exhaust gases back round to the intake manifold for burning again. Then under a heavy load, it should flap open for full exhaust exit. Mine used to stick shut so you would boot it and the car would just wheeze and strain like it was constipated. Then eventually the flap would open and you would rocket off... nightmare in traffic!!
