Mercedes-Benz Citan Throttle Body Replacement Parts

The Citan is powered exclusively by diesel engines (the OM607 and OM651 family), and diesel engines do not use a conventional throttle body in the way petrol engines do — fuel delivery is controlled by the injection system rather than by regulating airflow through a throttle. What diesel Citans do have is an EGR throttle valve (sometimes called an intake throttle or air management valve), which is a related but distinct component used to manage exhaust gas recirculation; this is likely what you are actually looking for. If you have seen a listing or been quoted for a 'throttle body' on a Citan, it almost certainly refers to this EGR-related intake valve rather than a conventional petrol-style throttle body.

The EGR throttle valve (intake throttle flap) on the Citan is fitted to the diesel engines — primarily the 1.5-litre OM607 unit used in the W415 generation (2012–2021) and the 1.1-litre engine in earlier lower-power variants — and its job is to partially restrict intake airflow to help pull exhaust gases through the EGR system rather than to meter fuel as on a petrol engine. Fitment of this valve is tied closely to the engine code, so you should confirm your engine code from your V5 or a VIN check before sourcing a used part. The engine code is the single most useful detail you can give a breaker when requesting a quote.

Both years fall within the W415 generation of the Citan (produced 2012–2021), so there is a reasonable chance of compatibility if the engine codes match — the OM607 1.5-litre diesel is the most common unit across this range. However, ancillary and mounting changes can occur mid-production even within a single generation, so you should confirm compatibility with the breaker against your specific registration rather than assume a straight swap. Always share your engine code when requesting a quote.

No, trim level does not affect which EGR throttle valve your Citan requires — Base, Worker, and Tourer variants all use the same engine-driven specification, so trim is irrelevant here. What matters is your engine code, fuel type (all Citans are diesel), and model year, not the badge on the van. You may find cosmetic differences between vans you're looking at for donor parts, but those have no bearing on whether the mechanical component will fit.

Many online listings use 'throttle body' loosely to describe the intake throttle flap or EGR throttle valve on diesel Citans, which is a different component from a petrol throttle body but serves a vaguely similar airflow-management role. To make sure you get the correct part, check your engine code on your V5 or via a VIN check and share it with the breaker along with your registration — this is far more reliable than going by year or trim alone. It is also worth confirming with the breaker whether the unit may require any ECU pairing or coding to your vehicle, as this can vary and is something to establish before purchase rather than after.
