Screaming Q7 - Crankcase breather valve

Audi started screeching at idle. Called my home mechanic and learned this is not unusual and is covered by an extended warranty from Audi. The problem is with the crankcase breather valve aka oil separator. Can I drive the 350 miles to get back home with this issu?.

Factory repair? Is there a dealer within this 350 mile distance?

Yes you should be able to drive home. Expect the check engine light to come on at some point. If it doesn’t, happy days.


ThankS, Mustangman. Made it to my destination. No CEL. Whistles loudly every time I let off the gas.

Calling Audi first thing Monday morning.
