Volkswagen LT Throttle Body Replacement Parts

It depends entirely on the engine fitted. The LT range (covering the Mk1 from 1975–1996 and the Mk2 from 1996–2006) was predominantly diesel-powered in UK specification, and diesel engines do not use a throttle body in the conventional sense — fuelling is controlled by the injection pump rather than an air throttle. Some petrol-engined variants of the LT did exist and would carry a throttle body, so if you have a petrol LT, check your engine code on the V5 or via a VIN check and supply it to the breaker.

Diesel engines, including the IDI and TDI units fitted to the LT across both generations, do not use a throttle body to control engine output — that function is handled by the fuel injection pump and, on later common-rail or unit-injector diesels, by the ECU and injectors directly. What you may be seeing on your diesel LT that looks like a throttle body is more likely an EGR valve, a vacuum-operated air flap, or an intake swirl flap assembly. Describe the exact component and its location to the breaker, along with your engine code, and they will identify the correct part.

Yes, the year matters because it affects which engine code was fitted, and the engine code is the detail that determines which throttle body is correct — not the body style or payload rating of the van. The LT Mk1 ran from 1975 to 1996 and the Mk2 from 1996 to 2006, and petrol engine specifications changed across and within those generations. Always supply your exact engine code (found on the V5 or a VIN check) to the breaker rather than just a year, as this is the most reliable way to match the part.

The LT28, LT35, and LT46 designations refer to payload and gross vehicle weight classes within the same LT range, not to fundamentally different vehicles — they shared the same engine families. Throttle body fitment follows the engine code rather than the weight variant, so if two vehicles share the same engine code, the throttle body should correspond; however, confirm this directly with the breaker against both registrations before purchasing, as ancillary or mounting details can vary.

On any diesel LT — which covers the vast majority of UK-registered examples — yes, this is very likely. Diesel engines use EGR valves, intake air shutoff flaps, or swirl control valves that can superficially resemble a throttle body in appearance and location. If you are unsure which component you need, photograph the part in situ and share it with the breaker alongside your engine code, as they will be able to identify the correct part from the registration and engine details.

No — trim level and body style (panel van, minibus, or chassis cab) have no bearing on throttle body fitment whatsoever. This is a mechanical component that follows the engine, not the bodywork or specification level. Supply the breaker with your engine code, fuel type, and registration, and they can cross-reference the correct part regardless of how your LT is bodied or trimmed.
