Second Hand Mercedes-Benz S-Class Coil Pack

Coil packs do exist on petrol-engined S-Class variants, but the W220 (1998–2005) and W221 (2005–2013) are entirely different generations with different engine families, so a straight swap is very unlikely to work even if the engine displacement sounds similar. What matters most is the engine code from your V5 or a VIN check – for example, an M113 in a W220 and an M273 in a W221 are not interchangeable despite both being V8 petrol units. Always confirm against your exact engine code with the breaker before buying.

No – coil packs are ignition components that only exist on petrol (spark-ignition) engines; diesel S-Class variants such as those badged 320 CDI, 350 CDI, or 400 CDI use compression ignition and have no coil pack or spark plugs at all. If your S-Class is a diesel and you are experiencing misfires or starting problems, the fault is more likely related to glow plugs, injectors, or fuel system components. Let the breaker know your fuel type upfront so they can point you in the right direction.

Both years fall within the W221 generation (2005–2013), and a 2011 facelift was introduced for this generation, which can bring minor ancillary changes even when the core engine code remains the same. If both cars share the same engine code – in this case the M272 3.5-litre V6 – fitment is likely to be closely related, but you should confirm with the breaker whether any mid-production or post-facelift mounting changes affect your specific build date. Quoting your registration or full VIN gives the breaker the best chance of matching the right unit.

Trim level does not affect coil pack fitment on the S-Class – AMG Line, SE, and similar designations describe interior and exterior specification, not the engine. What matters is the engine code, which will be the same across trim levels sharing the same badge. Bear in mind that used coil packs pulled from different trim cars may show cosmetic differences in wiring connectors or brackets, so confirm the part number or engine code match with the breaker.

Yes – the AMG S63 uses a twin-turbocharged V8 petrol engine (M157 in W221 or later generations) and the S65 a twin-turbocharged V12 (M275 or similar), both of which are petrol engines requiring coil packs and spark plugs. However, high-performance AMG engines often use individual coil-on-plug units per cylinder, and the specific part can differ significantly from a standard S350 or S500, so the engine code is especially important here. Confirm the exact engine code and build date with the breaker, as AMG variants are specialist units and pairing or coding requirements are worth querying directly.

The number depends on the engine – as a general rule, there is one coil pack per cylinder, so a V6 engine such as the M272 has six, a V8 such as the M273 has eight, and a V12 such as the M275 has twelve. Used S-Class coil packs from a breaker are typically sold individually, so knowing how many you need before you call will help you get an accurate quote. If you are replacing due to a misfire on a specific cylinder, give the breaker that detail too as some suppliers can identify the exact coil position.
