Our 2016 x3 is at 60,000 miles and dealer says we need to change the differential fluids. They’re asking $750.
I called an Instant Oil Change (a chain) location, and their price for this is $218.
Obviously I like the lower price.
But, that said, is there any reason to have the dealer change the differential fluids instead? The car is no longer under warranty.
Thanks!
