BMW X7 Glow Plugs Replacement Parts

Yes, glow plugs exist on the BMW X7, but only on diesel variants – the X7 was sold in the UK with diesel engines including the 30d (six-cylinder) and 40d (mild-hybrid six-cylinder) alongside petrol engines such as the 40i and M60i, which have no glow plugs at all. If your X7 is a petrol model, you will not find or need glow plugs for it. Check your V5 or run a VIN check to confirm your fuel type and engine code before searching.

The engine code is the most important detail you can supply – for the diesel X7, the B57 (straight-six 3.0-litre) is the core unit to know, and quoting it to the breaker ensures you get plugs matched to the exact engine rather than just the model badge. You'll find the engine code on your V5 registration document or via a VIN check. The number of cylinders also determines how many plugs are needed, so the breaker will want to confirm this too.

The BMW X7 G07 launched in 2019 and received a significant facelift in 2022, and while the B57 diesel engine carried across both, whether the glow plugs themselves interchange is something you should confirm with the breaker against your registration – minor ancillary or component-spec changes can occur mid-production that are not always visible from the outside. Give the breaker both your registration and your engine code and ask them to cross-reference the part number from the donor vehicle. Never assume a pre-facelift plug is a guaranteed drop-in fit for a post-facelift car without that check.

No – trim level (xLine, M Sport, Exclusive or any other) has no bearing on glow plug fitment whatsoever, as these are engine-driven mechanical parts and the trims are purely cosmetic or equipment-related distinctions. What matters is the engine code, fuel type, and production year. You may find parts sourced from a lower or higher trim look slightly different in their surrounding components, but the glow plug itself is determined by the engine, not the badge on the tailgate.

No – all UK-market BMW X7 models are xDrive four-wheel drive, so drivetrain layout is not a variable that changes glow plug fitment on this model. The relevant factors remain the engine code and production year. Focus your search on those details rather than the drivetrain designation.

The diesel X7's B57 engine is a straight-six, meaning it has six cylinders and therefore six glow plugs – one per cylinder. When sourcing from a breaker, you may be able to buy a full set of six or individual plugs depending on what the dismantler has available, so it is worth clarifying this when requesting a quote. Always confirm the engine code with the breaker so they can match the correct plug specification to your vehicle.
