Second Hand Mercedes-Benz G-Class Coil Pack

Yes, but only on petrol-engined variants — the G-Class has been sold in the UK with a range of petrol engines (including straight-six and V8 units) that use coil-on-plug or coil pack ignition systems, so coil packs are a genuine part on those models. Diesel variants, such as those running the OM602, OM603, OM612, OM647, or OM642 engine families, use compression ignition and have no spark plugs or coil packs at all. If you have a diesel G-Class and are chasing an ignition-related fault, you are more likely looking for a glow plug, glow plug relay, or injector. Always confirm your fuel type before searching.

The G-Class ran in its W463 generation from 1989 right through to 2018, so both a 2010 and a 2016 car sit within the same broad body generation — however, the engine codes changed significantly across that span, with Mercedes updating the petrol lineup (for example, moving from the M113 V8 to the M157 or M276 family in later cars), and coil packs follow the engine code, not the body shell. You need to match the engine code from your V5 or a VIN check to the donor vehicle's engine code, not just the year. Confirm the exact match with the breaker against your registration before buying.

Trim level and badge name make no difference to coil pack fitment in themselves — what matters entirely is the engine code fitted to that variant. The G350d is diesel and has no coil pack at all; the G500 uses a petrol V8 (engine code varies by year) and will need coil packs matched to that unit; the G63 AMG uses the M157 biturbo V8 and will need coil packs specific to that engine. So the trim name is just a useful shorthand for identifying which engine is under the bonnet — always cross-reference the engine code directly.

The W464 generation replaced the W463 from 2018 onwards, bringing a new platform and updated engine family (including the M176 V8 petrol), so the coil packs from a W463 are very unlikely to be a direct swap onto a W464 even if the displacement sounds similar. Engine codes are different between the generations, and the ancillary fitment and connector types may also differ. Tell the breaker your exact engine code and registration so they can confirm whether the part from their donor car matches yours.

The engine code matters above everything else for a coil pack — two G-Class cars from the same year could carry different engines depending on specification, market, or running changes, and a coil pack is built to the exact cylinder layout, connector type, and ignition timing requirements of a specific engine family. Your engine code is printed on your V5 logbook and can also be retrieved via a VIN check, and it typically looks something like M113, M157, or M176 on petrol variants. Always give the breaker your engine code alongside your registration to get an accurate match.

Gearbox type does not affect coil pack fitment — the ignition system is entirely independent of how drive is transmitted, so a coil pack from a manual-gearbox G-Class and one from an automatic with the same engine code should be interchangeable at the hardware level. The key variables remain the engine code and the model year within that engine's production run. That said, confirm with the breaker that there were no mid-production running changes to the ignition system on your specific engine variant, as these detail changes are worth double-checking against your registration.
