Hello....

I posted a reply in another thread today re engine judder on idle, and the fact that my local audi dealership replaced the EGR valve and appeared to have fixed it.

Well yes the car has no judder now, but the economy has fallen seriously, about 10 mpg. I'm going to call them in the morning, but surely the replacement of this valve shouldn't impact the cars economy like that !!?

Cheers.
