Used Vauxhall Grandland X Differential

The Grandland X ran as a single generation from 2017 to 2022 in the UK, with a facelift arriving in 2021, so the generation name stays the same throughout. Differentials are mechanically driven by engine code and gearbox type, so a pre-facelift (2017–2020) unit crossing into a post-facelift (2021–2022) car sits right on a production boundary where ancillary and mounting details can change mid-run. Name that boundary to your breaker and ask them to confirm compatibility against your exact registration before buying.

No — fuel type directly affects drivetrain specification, and a petrol-engine differential is not a straight swap onto a diesel-engine car even within the same model year. The engine code is the single most important detail here, as the differential is matched to that code above anything else. Always give the breaker your engine code (found on your V5C or via a VIN check) so they can source the correct unit.

Trim level — whether Sport Nav, Elite Nav, or Ultimate Nav — makes no difference whatsoever to differential fitment; these are cosmetic and equipment distinctions, not mechanical ones. What matters is engine code, fuel type, gearbox type (manual or automatic), and whether the car is two-wheel drive or four-wheel drive (the 4WD Grandland X uses an electrically driven rear axle with its own differential). Confirm those details with your breaker and trim can be ignored entirely.

Yes, gearbox type is one of the key fitment factors for a differential — a unit from an automatic car will not correctly match a manual transmission and vice versa. Give the breaker your gearbox type alongside your engine code and fuel type, as these three details together are what they need to find the right part. Never assume a swap will work based on year or badge alone.

The 1.5-litre diesel in the Grandland X is a PSA-family unit, but engine codes can vary by state of tune and market specification, so the safest approach is to read the exact code from your V5C or have it pulled from the VIN rather than relying on badge or displacement alone. Providing that precise code to the breaker is the single most useful thing you can do, as differentials follow the engine code above everything else. If you cannot locate it yourself, any breaker or motor factor can usually decode it from your registration.

The 2021 facelift marks a known production boundary for the Grandland X, and while the core drivetrain architecture is shared, ancillary mounting and specification details can differ across that boundary in ways that are not always obvious. Whether a specific post-facelift differential will drop straight into a pre-facelift car is something you should confirm with the breaker against both registrations rather than assume. Give them your engine code, gearbox type, and drive configuration (2WD or 4WD) and let them verify the match.
