Had the X in for replacement of the air pump. They handed me a bill for $50 + $40 in shop supplies. Service guy said on CPOs after 80,000km BMW charges a deductible. I refused to pay it and this morning had a look through my documents from purchasing. The only reference I can find is that a "BMW authorized retailer may charge a $50 handling fee, made payable to the BMW retailer, for handling warranty work." Now, that isn't BMW charging $50 for warranty work as I read it, anyone have any insight to share?

Thx
