I was just shocked with a $900 quote by the dealer for the 48 mo. service on our 2010 JSW TDi. We only have 25k miles on the car, so we're caught between the listed time and the mileage for maintenance. I'm wondering just how critical the fuel filter and trans service are with this low mileage. Should I get the engine oil & filter changed, and spread the rest out over the the next 6-12 months? Would VW really stiff me on the drivetrain warranty if something comes up in the final year and I had deferred that maintenance; e.g., transmission appeared, even if we're still far under the specific mileage for maintenance?
