Secure Transaction

Your payment info is protected at all times.

Cross-referenced parts are cataloged as fitting the same application but are not guaranteed to be identical to the original manufacturer part. Verify fitment against your OE number or VIN before ordering.

How to Confirm This Part Fits Your Vehicle

Reference/cross-reference numbers vary by engine, transmission, chassis and production date — not by number alone. Before ordering, compare your original OE number against 21543506 number by MERCEDES-BENZ listed above, and check the dimensions or specifications against your original part.

If you’re unsure, contact CarBus24 with your VIN or the number printed on your original part and we’ll confirm the correct match before you order.

Frequently Asked Questions

How do I know if a part matching 21543506 number by MERCEDES-BENZ fits my car?
