Used Mercedes-Benz S-Class Turbo

Both years sit within the W222 generation (2013–2020, facelift 2017), so there is a reasonable chance of compatibility if the engine codes match — the engine code is the single most useful detail here, as the turbo follows the engine rather than the model year or badge. However, ancillary fittings and mounting brackets can change quietly mid-production, so confirm the specific engine codes of both donor and recipient with the breaker against your registration before buying. Never assume fitment without that check.

The W222 S-Class ran from 2013 to 2020, with a facelift arriving in 2017, and while the core engine architecture was carried across that boundary, turbo specifications and ancillary fittings can change at a facelift point. Name the engine code from your V5 or a VIN check to your breaker and ask them to compare it against the donor car — this is the right way to establish whether the specific unit will cross the 2017 boundary safely. Route this question to the breaker rather than assuming the generation overlap means a direct swap.

Yes, trim and badge names on the S-Class reflect different engines entirely — the S350d is a diesel and the S500 is a petrol, so they use completely different turbos that are not interchangeable. Within the same engine variant, trim level itself does not affect turbo fitment; an S350d AMG Line and a standard S350d share the same engine code and the same turbo. Always confirm via the engine code on the V5 rather than relying on the badge or trim name alone.

The W221 (2005–2013) and W222 (2013–2020) are separate generations with different engine specifications, and turbos from the W221 are very unlikely to be a straight fit on a W222 even where the engine displacement looks similar on paper. Matching engine codes is essential — the codes changed between generations and even a like-for-like displacement can involve a different turbo unit, different oil feed fittings, and different mounting points. Treat this as a cross-generation swap and confirm all details with the breaker against both registrations before proceeding.

Yes, fuel type is a fundamental fitment factor — petrol and diesel turbos on the S-Class are entirely different units, built to different specifications and operating temperatures, and are not interchangeable under any circumstances. Within petrol or diesel, the specific engine code then determines exactly which turbo you need, as the S-Class range covers several distinct engines across its generations. Supply your engine code to the breaker alongside your registration to make sure you are quoted the correct unit.

The turbo itself is a mechanical component, so in principle it does not need to be coded to your car the way a control unit would — engine code compatibility is what drives fitment. That said, on modern S-Class models there can be sensor and actuator integration that touches the engine management system, and whether any coding or adaptation is required after fitting is something you should confirm with the breaker and your installer against your specific registration. Do not take it as given that a used turbo will be plug-and-play without checking this point.
