Second Hand BMW 3 Series Throttle Body

The BMW 3 Series does have a throttle body, but its design varies significantly by engine. Petrol engines across the E46, E90/E91/E92/E93, and F30/F31/F34 generations use an electronic throttle body (drive-by-wire), meaning there is a physical unit but it is controlled electronically rather than by a cable. Most diesel engines in the 3 Series use a different type of intake control valve rather than a conventional throttle body, so if you have a diesel, confirm with the breaker whether the part you need is genuinely described as a throttle body or an intake swirl flap or EGR valve instead.

The E46 ran from 1998 to 2006 and the E90 generation (saloon) from 2005 to 2011, so these are entirely different generations with different engine families and different throttle body designs. Even where engine displacements look similar — for example both generations had 2.0 and 2.5 petrol units — the engine codes differ and the throttle body dimensions, connector pinouts, and mounting arrangements are not shared. Always match by engine code rather than engine size, and confirm cross-generation fitment directly with the breaker against your registration number.

Trim level — whether SE, Sport, M Sport, or M Sport Plus — makes no difference to throttle body fitment on the BMW 3 Series; these are cosmetic and equipment packages, not mechanical variants. What matters is your engine code, which you can find on your V5C or via a VIN check, because even cars wearing the same badge and trim can have different engines fitted across a production run. Quote your engine code to the breaker and they will be able to match the correct unit regardless of what trim your car carries.

The E90-generation 3 Series received a facelift in 2008, and while many mechanical components carried over, ancillary details such as sensor positions, connector types, and mounting points on the throttle body can differ between pre- and post-facelift builds. The engine code is your most reliable guide here — if the engine code is identical on both donor and recipient cars, the chances of compatibility are much higher, but you should still confirm the specific build dates and any mid-run changes directly with the breaker before purchasing.

The F30 generation ran from 2012 to 2019, and within that range the 320i, 328i, and 330i all used variants of BMW's turbocharged four-cylinder petrol engine family, but the engine codes are not always identical between those badges. Some share the same physical throttle body unit, but displacement and state of tune differences can mean different calibrations or fitment details. Pull your exact engine code from the V5C or a VIN check and give it to the breaker — that single code is more useful than the badge on the back of the car.

Yes — body style has no bearing on throttle body fitment for the BMW 3 Series; the engine and its ancillaries are the same regardless of whether the car is a saloon, estate (Touring), coupe, or convertible within the same generation. The relevant details are the engine code, fuel type, and model year, not the body style. Confirm those with the breaker and body style can be disregarded entirely when sourcing this part.
