Cheap Peugeot 408 Throttle Body

It depends on the engine variant. The 408 has been sold with both petrol and diesel engines, and petrol engines do use a throttle body to control airflow; however, most modern diesel engines do not use a traditional throttle body in the same way, so if your 408 is diesel you are unlikely to need one. Check your fuel type and engine code on your V5 before searching.

Petrol-engined 408s — including the 1.6 THP and the later 1.2 PureTech turbocharged units — do have a throttle body as part of the intake system. The engine code printed on your V5 or available via a VIN check is the single most important detail to match, as different petrol engines use different throttle body units even within the same model year. Supply your engine code to the breaker so they can confirm the correct part.

The Peugeot 408 has gone through distinct generations — the first generation ran from 2010 to around 2014, and the current second-generation model launched in 2023 — and these generations use fundamentally different engines and engine management systems, so cross-generation fitment is very unlikely. Even within a generation, throttle body compatibility is driven by engine code rather than model year alone, so always match on engine code first. Confirm any cross-year swap with the breaker against your registration before purchasing.

No — trim level does not affect throttle body fitment on the 408. Whether your car is in Active, Allure, or GT trim, the throttle body is determined entirely by the engine code and fuel type, not by the trim or any cosmetic specification. Bear in mind that a used part may arrive without ancillary brackets or sensors that differ between production runs, so ask the breaker to confirm what is included with the unit.

This is something you should confirm with your fitting garage or the breaker rather than assume either way, as some modern throttle bodies on PSA-platform engines communicate with the ECU and may require adaptation or reset with a diagnostic tool after installation. Whether a full remap or immobiliser pairing is needed varies by engine and ECU specification, and this is not something that can be confirmed from the part number alone. Ask your breaker and your mechanic before committing to the purchase.

For the throttle body itself, gearbox type is not usually a primary fitment factor — the throttle body is part of the intake and engine management system, which is primarily matched to the engine code. However, some calibration or software differences can exist between automatic and manual variants on the same engine, so it is worth mentioning your gearbox type to the breaker when requesting a quote, particularly for later engine management systems where the two may be mapped differently.
