Cheap BMW M5 EGR Valve

No — the BMW M5 has never been fitted with an EGR (Exhaust Gas Recirculation) valve across any of its generations, including the E39, E60, F10, F90, and current G90. The M5's high-performance petrol engines are tuned for maximum output, and EGR systems — which recirculate exhaust gases to reduce emissions — are not used on these units, as they would compromise the power and throttle response the M5 is engineered to deliver. If you're searching for an EGR valve, it's very likely you have a standard 5 Series (520d, 525d, or similar diesel variant) rather than an M5, and you should search using your exact registration number to confirm your engine code.

Almost certainly not, and the mismatch goes beyond just the part number — the M5 does not have an EGR system at all, so there is no fitment question to answer. Diesel and lower-output petrol 5 Series models do carry EGR valves, but the M5's engine is a completely different unit with no provision for EGR. Double-check your registration against the parts listing and confirm your exact engine code with the breaker before purchasing anything.

It's worth verifying whether your vehicle is a genuine M5 or a 5 Series fitted with an M Sport trim pack, as M Sport models look very similar to the M5 but use standard 5 Series engines that can include EGR valves on diesel variants. The easiest way to check is to look up your registration on a free DVLA checker or ask the breaker to confirm the engine code — a genuine M5 will show an S-prefix high-performance petrol engine, which has no EGR. If your car turns out to be a diesel or standard petrol 5 Series in M Sport trim, the breaker can then help you find the correct EGR valve matched to your specific engine code and emissions standard.

No — and the situation is straightforward here: the M5 does not have an EGR valve fitted, so there is no compatible part to cross-reference regardless of what the donor car is. The M550d is a diesel and the 550i is a standard petrol, both from the mainstream 5 Series range rather than the M division, and their drivetrain components are not shared with the M5. If you need an EGR valve for an M550d or 550i, search by your engine code and confirm the emissions era (Euro 5 or Euro 6) with the breaker, as this affects which units are compatible.

This question doesn't apply in practice because neither the F10 M5 (2011–2016) nor the E60 M5 (2005–2010) was ever fitted with an EGR valve — it is simply not part of these vehicles' engine configurations. The M5 across all generations uses bespoke high-performance petrol engines that do not use exhaust gas recirculation. If you are trying to source emissions-related components for an M5, confirm with the breaker exactly what part your garage has identified, as it may be a different emissions component such as a secondary air pump or oxygen sensor.
