Many thanks for this. I've read the bit on the ETM (very scary, wish I'd seen that before I bought the car!) but this suggests the pre 2002 models are mostly affected ( )mine is a 2003 so before i go that route I think I'll see what a service does for the car. I've not had any rough running or lumpy idling or anything like that, just that in some low speed situations the revs go very low, ie when in traffic with no throttle pressure at all. Its also a lot thirstier than my previous 20v 2.0 850 auto estate was. That car really improved after a decent service. I think the cam belt will be changed, what sort of cost is this likely to be? Also I used to use a good independent garage, do they have to have volvo computer diagnostics to do a decent service or am I blessed with main dealer prices? I have to say this site is a real mine of information, its going t oabsorb a lot of my time reading this stuff!:wink_smile: if I'm allowed by the boss that is!
