Used Mercedes-Benz GLB Coil Pack

Yes, but only on petrol-engined GLB variants — coil packs are ignition components used exclusively on petrol engines, so if your GLB is a diesel (for example, the 200d or 220d), it does not have coil packs at all and you will need to look for glow plugs instead. Petrol variants such as the GLB 200 and GLB 250 use a spark-ignition system and do have individual coil packs, typically one per cylinder. Check your V5 or run a VIN check to confirm your fuel type and engine code before searching.

The Mercedes-Benz GLB (X247) is a single generation launched in 2019, so a 2020 and a 2023 car sit within the same generation — however, there was a facelift in 2023 which brought some updates, and it is worth confirming with the breaker whether any ancillary or mounting changes affect coil pack compatibility across that boundary. The most reliable way to match the part is to share your exact engine code (found on your V5 or via a VIN check) with the breaker, as the coil pack follows the engine specification rather than the model year alone. Never assume fitment without that check.

No — trim level does not affect coil pack fitment on the GLB; AMG Line, Sport, and Progressive are cosmetic and equipment packages, not mechanical ones, and the coil pack is determined entirely by the engine code. Two GLBs with the same engine code will use the same coil pack regardless of which trim specification they carry. Just confirm your engine code with the breaker and ignore the badge.

Yes, engine code is the single most important detail for this part — different petrol engines in the GLB range (for example the M282 in the GLB 200 and the M260 in the GLB 250) use different coil packs that are not interchangeable. Your engine code is printed on your V5 logbook or can be retrieved via a VIN check, and you should always give this to the breaker rather than relying on the badge name alone. Getting this wrong is the most common cause of buying the wrong ignition part.

It is possible that GLB petrol engines share specifications with those found in the A-Class (W177) or CLA (C118), and if the engine codes match exactly the coil packs may well be interchangeable — Mercedes-Benz used the same engine families across several models in this era. However, you should always confirm this directly with the breaker, quoting your GLB engine code and asking them to cross-reference it against the donor vehicle, as minor production changes can affect compatibility even between cars sharing a platform. Do not assume fitment based on engine name alone.

Coil packs are generally passive components and do not typically require electronic coding in the way that modules or ECUs do — in most cases a used coil pack can be swapped directly without specialist programming. That said, whether any pairing or immobiliser consideration applies to your specific GLB variant is something you should confirm with the breaker or a Mercedes-specialist technician before purchase, as this is an area where guidance can vary. It is always worth asking the question rather than assuming.
