A used instrument cluster that fits one vehicle won't always fit another - even within the same model range. These questions help breakers match stock to your exact vehicle before they quote:
Both your 2002 and 2004 cars fall within the R170 generation (1996–2004), so there is a reasonable chance of compatibility, but you should confirm the exact part number with the breaker against your registration before buying, as minor updates within a generation can affect interchangeability.
The R170 (1996–2004) and R171 (2004–2011) are different generations with different dashboards and electrical architectures, so a cluster from one will not simply swap into the other. Stick to a cluster from the same generation as your car, and confirm the part number with the breaker against your registration.
The engine variant does not affect which instrument cluster is fitted — fitment is determined by the generation and trim level rather than the engine. You should therefore not restrict your search by engine, but do confirm the exact specification with the breaker against your registration to make sure the cluster matches your car's build.
Trim level can affect the cluster because higher-spec and AMG variants sometimes have different display layouts or additional gauges compared with standard trim cars. When buying used, confirm with the breaker that the cluster came from a car matching your own trim specification to avoid cosmetic or functional mismatches.
The R171 received a facelift in 2008, and although both cars share the same generation name, electrical and software updates mean a cluster from one side of that boundary may not be directly compatible with the other. Name the facelift year and your registration when speaking to the breaker so they can check part numbers and confirm fitment before you commit.
Physically removing and refitting the cluster is something many experienced home mechanics tackle, but the cluster often needs to be coded to the car's ECU and mileage, which typically requires specialist diagnostic equipment. It is strongly advisable to have the coding carried out by a garage or auto electrician to ensure the cluster reads correctly and does not cause warning lights or other faults.
