Used egr valves vary between vehicles - and whether you call it used, second hand or a replacement, matching the right one matters. These are the details breakers need to match the right part to your car - our request form asks them so you only hear from suppliers with the correct part:
Yes, EGR valves were fitted to the majority of Peugeot 407 engines, particularly the diesel units such as the 1.6 HDi, 2.0 HDi, and 2.7 HDi V6 — these engines use exhaust gas recirculation to reduce NOx emissions and meet Euro emissions standards. The petrol-engined 407s (such as the 1.8 and 2.2 petrol) also had EGR systems fitted, though EGR faults are far more commonly reported on the diesel variants. So unless you have an unusual or modified vehicle, an EGR valve almost certainly exists on your 407.
Yes, engine code is the single most important factor — the 407 was sold from 2004 to 2011 with several different diesel engines (including the DW10 family in various states of tune and emissions specification), and the EGR valve design can differ between them even when the engines look similar. Always check your engine code from the V5C or the engine bay sticker rather than going by engine size alone, as a 2.0 HDi could carry different codes across the production run. Confirm the exact engine code with the breaker before purchase.
The 407 received a facelift in 2008, and while the body and interior changed, many of the diesel engine codes carried over — however, emissions calibration and engine management updates mean that an EGR valve from the pre-facelift era is not guaranteed to be a straight swap for a post-2008 car. The facelift period also saw refinements to meet tightening Euro emissions standards, which can affect sensor integration on the EGR unit. Name the boundary clearly to the breaker and confirm against your exact engine code and registration before buying.
No, trim level makes no difference to EGR valve fitment on the 407 — trims like SE, S, and Sport are cosmetic and equipment-level distinctions that do not alter the engine or emissions hardware. What matters entirely is the engine code and fuel type, not whether your car has leather seats or a higher-spec dashboard. You can disregard trim when searching, but do confirm engine code with the breaker.
No, body style does not affect EGR valve fitment — the saloon and SW estate shared the same engine family, and the EGR valve is part of the engine and emissions system, not the bodywork or drivetrain layout. A valve sourced from an SW with the same engine code as your saloon (or vice versa) should be compatible, subject to engine code matching. Always confirm with the breaker against your registration to be certain.
No, the 2.7 HDi V6 is a significantly different and more complex engine than the four-cylinder HDi units, and its EGR system is not interchangeable with the 1.6 or 2.0 HDi valves. The 2.7 HDi was a joint PSA-Ford unit and parts from the four-cylinder range will not fit it. Make sure the breaker you contact specifically has the part sourced from a 2.7 HDi 407 or equivalent vehicle using the same engine.
