Mercedes-Benz C-Class Differential Replacement Parts

This is a generation-boundary question: the W204 C-Class ran from 2007 to 2014 (facelift from 2011), while the W205 generation began in 2014, so a 2010 unit and a 2014 unit could be from entirely different platforms depending on the exact build date. Within the W204 generation, whether a pre-facelift or post-facelift differential crosses over depends on your engine code, gearbox type, and any mid-run specification changes, so confirm the exact compatibility with the breaker using your registration number. Never assume a year match alone guarantees a swap.

Trim level — whether that's SE, Sport, AMG Line, or Avantgarde — does not determine which differential is fitted; what matters is the engine code, fuel type, and gearbox type underneath. A C220d with a 9G-Tronic automatic will share its differential specification with another C220d automatic regardless of whether one is badged AMG Line and the other SE. Supply the breaker with your engine code (found on your V5 or via a VIN check) rather than your trim name and they can match the right unit.

A 2016 C-Class sits within the W205 generation, which ran from 2014 onwards, so you should be sourcing a differential from another W205 car. Fitment within that generation is driven by engine code and gearbox type above everything else — a rear-wheel-drive diesel automatic will not share a differential with a 4MATIC all-wheel-drive variant, for example. Give the breaker your engine code and confirm whether your car is RWD or 4MATIC to make sure the unit is correct.

For the differential itself, body style — saloon or estate — does not affect fitment; the mechanical specification follows the engine code, gearbox type, and drivetrain layout rather than which body the car wears. You may find minor ancillary or mounting differences between variants, so it is worth confirming with the breaker against your registration that the specific unit matches before purchasing. Focus on matching the engine code and gearbox type and the body style of the donor car becomes irrelevant.

The W203 ran from 2000 to 2007 and the W204 from 2007 to 2014, and these are distinct generations with different platform architectures, so a straight swap is not something you should assume. Even where engine families overlap between generations, the differential housings, ratios, and mounting points can differ significantly. Route this question directly to the breaker along with both engine codes and your registration so they can check actual part numbers rather than relying on generation logic alone.

Yes — the engine code stamped on your V5 or revealed by a VIN check is far more reliable than the badging on the boot lid, because Mercedes has used different internal engine variants under the same displacement badge at different points in production. Two cars both badged C250d could carry different engine codes and potentially different differential specifications depending on gearbox and drivetrain. Always supply the breaker with the actual engine code rather than the badge name to get the most accurate match.
