Cheap Mercedes-Benz ML Coil Pack

Only petrol-engined ML variants use coil packs — diesel engines (which make up the majority of UK ML sales, covering engines like the 270 CDI, 320 CDI, 350 CDI, and 420 CDI) use a compression-ignition system and have no coil packs at all. If your ML is a petrol — such as the ML320, ML350, or ML500 — then yes, it will have a coil pack or individual coil-on-plug ignition coils. Check your V5 or run a VIN check to confirm your fuel type and engine code before searching.

The W163 ran from 1997 to 2005 and the W164 from 2005 to 2011 — these are entirely different generations with different engine families, so coil packs from a W163 petrol will not cross over to a W164 petrol. Even where displacement sounds similar (for example, both generations offered a 3.5-litre V6 petrol), the engine codes differ and the ignition components are not the same. Always supply your engine code — found on your V5 or via a VIN check — to the breaker so they can match the correct coil.

Both fall within the W164 generation (2005–2011), which received a facelift around 2008, so there is a production boundary to be aware of within those years. Engine codes for petrol variants did not change wholesale at the facelift, but ancillary and mounting changes mid-production are possible — confirm compatibility against your exact registration with the breaker rather than assuming all W164 petrol coils are interchangeable. Supplying your engine code gives the breaker the best chance of finding the right part quickly.

Trim level makes no difference to coil pack fitment — Sport, SE, and other trim designations on the ML relate to equipment, interior spec, and cosmetic features, not the engine or ignition system. What matters is the engine code, which will be identical across trim levels sharing the same powertrain. Buy on engine code, not on badge or trim name.

The W166 ran from 2011 to 2015, and in the UK the overwhelming majority were diesel-powered (ML250 BlueTEC, ML350 BlueTEC), meaning they have no coil packs. There was a petrol ML350 on the W166 in some markets, but UK supply was very limited — check your V5 fuel type and engine code to confirm whether your vehicle is petrol or diesel before searching for ignition parts.

Coil packs themselves are passive components and do not generally require electronic coding, unlike some other Mercedes parts. However, if a fault has triggered stored diagnostic trouble codes you may need the codes cleared after fitting, and any wider ignition or ECU issues should be investigated — confirm the specifics of your vehicle's requirements with the breaker or a qualified technician against your registration.
