Second Hand BMW X5 Glow Plugs

Glow plugs are diesel-only components — they pre-heat the combustion chamber to aid cold starting in compression-ignition engines. No petrol-engined BMW X5 has ever been fitted with glow plugs, so if your X5 is a petrol model (for example the 3.0i, 4.4i, or 4.8i), this part simply does not apply to your vehicle. If your petrol X5 is having cold-start problems, you are more likely looking at spark plugs, ignition coils, or related components. Confirm your fuel type from your V5C before ordering anything.

These are two distinct generations — the E53 ran from 2000 to 2006, and the E70 ran from 2007 to 2013 — and the diesel engines used across them are quite different, meaning glow plugs are unlikely to interchange between the two. The E53 diesel used the M57 engine family, while the E70 diesel used later M57 and N57 units, each with their own plug specification. Engine code is the deciding factor here, so supply your exact code (found on your V5C or a VIN check) to the breaker rather than relying on generation alone. Never assume fitment across a generation boundary without the breaker confirming against your specific registration.

Within the E70 generation (2007–2013, with a facelift in 2010), fitment is driven primarily by engine code rather than model year. If a 2008 and a 2012 X5 share the same engine code — for example both being the 30d with the same M57 or N57 unit — the glow plugs are very likely the same, but there can be mid-production specification changes that are not always visible from the year alone. Always give the breaker your exact engine code alongside the registration so they can cross-reference their donor vehicle and confirm before sending the part.

Both the 30d and 35d are six-cylinder diesel variants, so both will have six glow plugs in total — one per cylinder. However, the 35d uses a different engine tune and in some markets a twin-turbo setup, which may mean a different plug specification to the 30d even if the cylinder count matches. Treat the engine code as the definitive guide and provide it to the breaker, who can match it against the donor vehicle rather than relying on the badge designation alone.

Trim level has no bearing on glow plug fitment whatsoever — SE, M Sport, xLine, and any other trim designation are purely about cosmetics and equipment levels, not the engine internals. What matters entirely is your engine code, which will be the same across all trim levels fitted with the same diesel engine. Give the breaker your engine code and registration rather than your trim name, and you can safely ignore trim differences when sourcing this part.

The F15 is the third generation X5, running from 2013 to 2018 with a facelift around 2016, replacing the E70 (2007–2013), and the diesel engines changed significantly between the two — moving further into the N57 family and later variants. Because of this, glow plugs from an E70 and an F15 are unlikely to be a direct swap, even on models with similar badging such as the 30d. Name your generation to the breaker, supply your engine code, and let them confirm fitment against their specific donor vehicle before purchasing.
