Until September 2026 this page listed a timing belt price for Mercedes-Benz. That was wrong. Mercedes-Benz engines use a metal timing chain that is designed to last the life of the engine and has no service interval, so there is nothing to quote and no fair price to compare against. Our timing belt guide explains the difference between the two designs and how to check which one your car has.
What a Timing Belt Quote on a Mercedes-Benz Usually Means
- A mislabeled line. Mercedes-Benz vehicles do have a serpentine (accessory) belt, a routine and inexpensive replacement that some estimates label loosely. Ask which belt.
- Timing chain work. A stretched chain, a failed tensioner or worn guides are real Mercedes-Benz repairs, but they are engine-specific jobs quoted on their own, not a belt service.
- An upsell. If the shop cannot name the part, walk away. Our timing belt guide lists this exact situation as a red flag.
What to Do
- Ask for the part number in writing. A belt and a chain kit are different parts at different prices.
- Get the job itemized. Parts, labor hours and the labor rate on separate lines. Mercedes-Benz dealerships charge $140 to $280 per hour in labor.
