Used Mercedes-Benz GLC Fuel Injection Pump

The GLC first generation (X253) ran from 2015 to 2022 with a facelift in 2019, so a 2016 and a 2019 are both X253 generation but sit either side of that facelift boundary. Fitment depends primarily on the engine code rather than the model year, so if both cars share the same engine code the pump may well interchange, but ancillary mounting or connector changes introduced at the 2019 facelift mean you should confirm compatibility with the breaker against your specific registration before buying.

These are different engine variants — the 220d typically uses a four-cylinder diesel engine and the 250d a more powerful variant of a similar family, but the engine codes are distinct and fuel injection pumps follow the engine code, not the badge name. Sharing the same broad engine family does not guarantee the pump is identical, so always supply your engine code (found on your V5C or a VIN check) to the breaker to confirm the correct part before purchasing.

No, trim level does not affect fitment for a fuel injection pump — AMG Line, Sport, and other GLC trim designations relate to cosmetic and suspension specification, not the engine internals. What matters is the engine code, fuel type, and gearbox type, so a pump from an AMG Line car with the same engine code as your Sport will be mechanically the same unit; the only differences you might notice are cosmetic marks or brackets on surrounding components from the donor vehicle.

The engine code is the single most important detail for matching a fuel injection pump, sitting above model year, badge, or trim level. You can find your engine code on your V5C registration document or by running a VIN check, and quoting it directly to the breaker is the most reliable way to ensure you are quoted the correct part. Without the engine code, year and fuel type alone may not be enough to guarantee a match on a diesel injection pump.

No — fuel type is a fundamental fitment factor and petrol and diesel fuel injection systems are entirely different by design and not interchangeable. When contacting a breaker, always confirm both your fuel type and your engine code to make sure the quoted pump is from a diesel donor vehicle matching your specification.

Both years fall within the first-generation GLC (X253, 2015–2022), which is a good starting point, but the 2022 car is post-facelift (facelift introduced 2019) and there may have been ancillary or mounting changes across that production run. The engine code is your most reliable guide, so compare codes between the donor and your car and ask the breaker to confirm compatibility against your registration before committing to the purchase.
