Used Mercedes-Benz CLS Coil Pack

The CLS range has always included both petrol and diesel engines, and coil packs are a petrol-engine component — diesels use glow plugs instead of spark ignition, so they have no coil packs at all. If your CLS has a petrol engine (for example a C219 with the M272 V6 or M156 V8, or a C257 with the M256 inline-six), it will have coil packs. Check your V5 or run a VIN check to confirm your fuel type and engine code before searching.

These sit in different generations — the first-generation CLS (C219) ran from 2004 to 2010, while the second-generation (C218) ran from 2011 to 2018 — so the answer is almost certainly no, they are different platforms with different engine families. Even within a generation, the engine code is the detail that really determines which coil pack fits, not the model year alone. Supply your engine code (found on the V5 or a VIN check) to the breaker so they can match the part correctly.

The C218 second-generation CLS ran from 2011 to 2018, and the C257 third-generation followed from 2018 onwards, bringing new engine families such as the M256 inline-six petrol. Because the engine families changed across that boundary, a coil pack from a C218 petrol is very unlikely to suit a C257. Confirm the exact engine code with your breaker against your registration, as coil pack design can also vary within a generation depending on which petrol unit is fitted.

No — trim level does not affect coil pack fitment at all on the CLS; AMG Line, Sport, and SE are cosmetic and equipment packages, not mechanical changes. What matters is the engine code, which is the same across trim variants sharing the same engine. Give the breaker your engine code and they will be able to match the correct coil pack regardless of which trim your car is.

The number of coil packs matches the number of cylinders — a four-cylinder petrol needs four, a V6 needs six, and a V8 needs eight, with one coil per cylinder in the individual coil-on-plug arrangement these engines typically use. If you are buying from a breaker, it is worth asking whether they can supply a full set pulled from the same donor engine, as mixing coil packs of different ages and mileage can sometimes cause running issues. Confirm the cylinder count for your specific engine code when contacting the breaker.

If the engine code is genuinely identical, the coil pack itself may well be the same part, as Mercedes-Benz used several engine families across multiple models in the same era. However, ancillary fittings or connector types can sometimes differ between applications even with a shared engine code, so you should confirm compatibility with the breaker against both registrations rather than assuming a straight swap. A good breaker will be able to cross-reference the part number from both donor vehicles before you commit.
