Cheap Mercedes-Benz G-Class Catalytic Converter

The W463 G-Class ran from 1989 through to 2018, with significant engine and emissions changes across that long lifespan — particularly around the Euro 5 and Euro 6 transitions — so a cat from an early W463 is very unlikely to suit a later one even though the body looks similar. The engine code and emissions era are the critical matching points, and interchange specifics across these boundaries are strong confirm-with-breaker territory. Always give the breaker your registration so they can check the exact engine code and emissions standard before agreeing a sale.

The W464 (2018-onwards) introduced substantially different engine configurations compared to the outgoing W463, including revised straight-six and V8 units built to Euro 6 standards, so cross-generation fitment is very unlikely. Whether any specific part crosses that 2018 W463-to-W464 boundary is exactly the kind of interchange question you need to confirm with the breaker against your registration. Do not assume physical similarity means the part will fit or pass MOT.

Yes, but it is the engine that drives the difference here, not the trim name itself — the G350d runs a diesel engine and the G500 a petrol V8, so they require completely different catalytic converter systems. Trim level as such does not matter; what matters is the engine code and fuel type, both of which differ entirely between those two variants. Give any breaker your exact registration and they can confirm the correct engine code match.

Diesel G-Class models have both a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF) as part of the exhaust aftertreatment system — they are separate components serving different functions. Whether a used unit from another diesel G-Class will interchange correctly depends on the exact engine code and emissions era, which is confirmed-with-breaker territory. A part from the wrong emissions generation may not fit correctly or could cause an MOT failure.

Yes, all petrol G-Class variants are fitted with catalytic converters as standard, and given the long production life of this model there are meaningful differences between earlier and later units tied to Euro 5 and Euro 6 standards. The engine code is the primary matching factor, and even within the same fuel type a cat from a different engine or emissions era is unlikely to be correct. Confirm the engine code and emissions generation with the breaker using your registration before purchasing.

Both the G63 AMG and the G500 use petrol V8 engines, but they are different engine variants with different specifications, meaning the exhaust systems including the catalytic converters are not the same. Trim level itself is not the fitment factor, but the differing engine codes between AMG and non-AMG variants almost certainly mean the cats are not interchangeable. Confirm the engine code on both donor and recipient vehicles with the breaker before agreeing any purchase.
