Quick answer: You can service a BMW, Mercedes-Benz, Audi, Volkswagen or Porsche at an independent shop without voiding the factory warranty, as long as the work follows the manufacturer’s maintenance schedule and uses parts and fluids that meet its specifications. Under the federal Magnuson-Moss Warranty Act, a manufacturer generally cannot require you to use the dealer or brand-name parts as a condition of the warranty. Keep your receipts. Free warranty repairs and recalls still go to the dealer.
What an independent European specialist does well
- Brakes and rotors, including the large rotors and electronic parking brakes on newer models.
- Suspension: control arms, bushings, struts and air suspension, which wear quickly on heavier German cars on New Jersey roads.
- Oil service with oil that meets the factory approval for your engine.
- Diagnostics for check-engine lights, misfires, oil leaks and coolant leaks.
When the dealer still makes sense
Use the dealer for repairs covered free under warranty, for open recalls, and for a few software updates that only the dealer can perform. For everything you are paying for yourself, compare quotes.
