Cheap BMW X1 Glow Plugs

Glow plugs are exclusively a diesel engine component — they pre-heat the combustion chamber to aid cold starting in compression-ignition engines. Petrol X1s (including all sDrive18i, sDrive20i, and xDrive28i variants) use spark plugs instead and never had glow plugs fitted. If you have a petrol X1 and are having cold-start issues, you'll want to look at spark plugs, ignition coils, or fuel system components rather than glow plugs.

The E84 (2009–2015) and F48 (2015 onwards) are completely different generations with different engine families, so glow plugs from one will almost certainly not cross over to the other. The critical thing is the engine code — for example, an E84 running the N47 diesel engine uses different plugs to an F48 running the B47. Always supply your engine code (found on your V5 or via a VIN check) to the breaker so they can match the part precisely, and never assume generation-to-generation fitment.

Trim level makes no difference whatsoever to glow plug fitment — SE, Sport, xLine, and M Sport X1s all share the same engine hardware within each engine variant. What actually matters is the engine code, which is identical across trims paired with the same engine. Focus on supplying the engine code and fuel type to your breaker, and ignore the badge on the tailgate.

Both years sit within the E84 generation (2009–2015), so fitment is plausible if the engine codes match — the N47 four-cylinder diesel was common across this range. However, confirm the exact engine code with the breaker against your registration before buying, as there were specification changes within the E84 production run that could affect ancillary details. Matching engine code to engine code is the safest approach.

No — the xDrive or sDrive designation relates to the drivetrain layout and has no bearing on glow plug fitment. Glow plugs are determined entirely by the engine code and fuel type, not by how the power is delivered to the wheels. An xDrive20d and an sDrive20d sharing the same engine code will use identical glow plugs, so simply match on engine code when speaking to your breaker.

Most four-cylinder diesel X1 engines (such as the N47 and B47) use four glow plugs — one per cylinder — so you'd typically need a full set of four for a complete replacement. When buying used from a breaker, confirm you're getting the right quantity for your engine and that all plugs are from the same engine code to ensure consistency. Your breaker can advise based on your registration or engine code, so have that detail ready when you call.
