Used Mercedes-Benz CLS Throttle Body

It depends entirely on the engine. Petrol-engined CLS models — such as those fitted with the M272 or M273 V6 and V8 units — do use a throttle body to regulate airflow into the engine. Most diesel CLS variants (the OM642 and similar CDI units) use a different airflow management system and do not use a conventional throttle body in the same way, so if you drive a diesel CLS you may be looking for a different part — confirm with your breaker what your specific engine actually uses.

Almost certainly not — the W219 (2004–2010) and C257 (2018–2023) are entirely different generations built around different engine families, so the throttle bodies are not interchangeable. The engine code printed on your V5 or obtained via a VIN check is the detail that actually determines fitment, and you should supply that to your breaker rather than just the generation name. Even within a generation, engine variants differ, so matching on engine code is essential.

The W219 ran from 2004 to 2010 with a facelift arriving around 2008, and while many mechanical components carried over, ancillary mounting and connector details can change mid-production even on the same engine family. The safest approach is to give your breaker your full engine code and registration so they can check the specific part number rather than assuming pre- and post-facelift units are identical.

No — on a petrol CLS, the throttle body is determined by the engine code, not by whether the car is a standard, AMG Line, or full AMG variant. Breakers may pull throttle bodies from cars with different interior specifications and exterior styling, and that makes no difference to mechanical fitment. Just confirm your engine code matches, and don't be put off if the donor car had a different trim level to yours.

The C218 ran from 2011 to 2018 with a facelift in 2014, and fitment within this generation depends primarily on which petrol engine you have — for example, a 3.0-litre V6 unit will not share a throttle body with a 5.5-litre V8 even within the same body shell and generation. Supply your engine code to the breaker to make sure the part matches your specific variant, as engine options changed across the production run.

Some Mercedes-Benz throttle bodies require adaptation or coding to the vehicle's ECU after installation, and this can vary depending on the engine and the control unit fitted to your specific car. Whether a used unit will pair correctly with your car without additional work is something you should confirm with your breaker and a Mercedes-specialist or auto-electrician before purchasing, as this is not something that can be guaranteed from the part description alone.
