Cheap BMW 6 Series EGR Valve

Yes, but only on diesel-engined variants — the EGR valve is part of the exhaust gas recirculation system used on diesel engines to reduce NOx emissions, and the BMW 6 Series was offered with several diesel units (including the 3.0-litre straight-six diesels found in the 630d and 640d). Petrol-engined 6 Series models (such as the 640i and 650i) do not have an EGR valve, so if your car is a petrol variant you are looking for a different part. Always confirm your engine code with your breaker before ordering.

Almost certainly not — the E63 and E64 generation ran from 2003 to 2010 (with a facelift around 2007), while the F12 (convertible), F13 (coupé), and F06 (Gran Coupé) generation ran from 2011 onwards, and these generations used different diesel engine families with different EGR configurations. The engine codes are the starting point for fitment, and even where engine displacement looks similar the ancillaries changed significantly across this generational boundary. Confirm the exact engine code from your V5C or door-jamb plate and share it with your breaker before agreeing a purchase.

Both the 2012 and 2014 640d sit within the F12/F13/F06 generation (2011 onwards) and share the N57 diesel engine family, so there is a reasonable chance of compatibility, but you must match on the exact engine code suffix as BMW updated engine specifications and emissions calibration across the model run to meet Euro 5 and Euro 6 requirements. An EGR valve from the wrong emissions era may not function correctly or could cause issues at MOT. Give your breaker your full engine code and registration to confirm before buying.

No — trim level has no bearing on EGR valve fitment on the BMW 6 Series; SE, Sport, M Sport, and M Performance trims all use the same valve for a given engine code. The EGR valve is determined entirely by the engine code and emissions specification of the car, not by interior or exterior trim. Your breaker will want your engine code and registration, not your trim level.

Within the F-series generation, the F13 coupé, F12 convertible, and F06 Gran Coupé all shared the same diesel engine options, so EGR valve fitment follows the engine code rather than the body style. If the engine codes match, the body style itself is not a barrier to the part fitting. Confirm the engine code with your breaker as the primary check.

The most important information is your full engine code (found on your V5C logbook or stamped on the engine bay), your registration number, and the fuel type (diesel only — petrol 6 Series do not have EGR valves). It is also worth noting your car's year of first registration, as this helps the breaker identify whether the part is from the correct emissions era (Euro 5 or Euro 6). The more detail you provide upfront, the better chance your breaker has of finding a correctly matching used part.
