That's bizzare. It's the one that was on the 200q20v when I bought it and
it ran like a champ. The Urq doesn't have one even remotely like it.
Haven't checked the other one I eplaced it with. In any case, glad yours is
working again. Now that I looked under the No., according to ETKA, it's for
the UrS4/S6 cars...
