Used Peugeot 407 Throttle Body

It depends on the engine: petrol-engined 407s do have a throttle body, but diesel variants — which made up the majority of 407s sold in the UK — do not use a traditional throttle body in the same way, instead using a different air management system. If your 407 is a diesel (1.6 HDi, 2.0 HDi, 2.2 HDi, 3.0 HDi), you are unlikely to need a conventional throttle body and may be looking for an EGR valve, inlet manifold swirl flap motor, or throttle actuator instead — confirm with a breaker what the correct part is for your exact engine. Petrol 407 owners (1.8, 2.0, 2.2 and 3.0 V6 petrol engines) should proceed with a throttle body search, quoting their engine code to the breaker.

The 407 ran as a single generation from 2004 to 2011, with a facelift in 2008 that brought styling and some equipment changes but generally retained the same engine family. For throttle body fitment, the engine code is what matters above all else — if both cars share the same engine code (for example, both are the 2.0 petrol EW10 family), the part is likely compatible, but ancillary mounting or sensor connector changes can occur mid-production. Name both registration plates and engine codes when asking your breaker, and let them confirm compatibility before purchase.

No, the 407's trim levels — S, SE, SE Sport, and GT — do not affect which throttle body you need, as this is a mechanical part determined entirely by the engine fitted, not the badge on the boot. A 2.0 petrol SE and a 2.0 petrol GT will use the same throttle body provided they share the same engine code. Focus your search on matching the engine code (found on your V5 or via a VIN check) rather than the trim designation.

Body style has no bearing on throttle body fitment — the engine and its associated components are the same regardless of whether the car is a saloon, SW estate, or the 407 Coupe. As long as the engine codes match, a throttle body from any body style of the 407 range should be mechanically interchangeable. Always quote your engine code to the breaker to be sure.

This is an area where you should confirm with the breaker rather than assume either way — on some petrol engines with electronic throttle control, the throttle body or associated ECU settings may need to be reset or adapted using diagnostic equipment after fitting a used unit. This is not something that can be stated as fact across all 407 petrol variants, so ask your breaker and plan to have the work carried out by a garage with the appropriate diagnostic tools if needed. Budgeting for a basic throttle body adaptation procedure is sensible when fitting a used electronic throttle body.

For petrol-engined 407s, the common engine codes include the EW7 (1.8 petrol), EW10 (2.0 petrol), EW12 (2.2 petrol), and the ES9 (3.0 V6 petrol) — these are the variants most likely to require a conventional throttle body. Your exact engine code will be on your V5 registration document or can be confirmed via a VIN check, and supplying it to the breaker is the single most useful thing you can do to ensure you get the right part. Diesel 407 owners should not be searching for a throttle body and should instead describe their symptoms to the breaker who can identify the correct part.
