Used BMW M3 EGR Valve

No — the BMW M3 has never been fitted with an EGR (Exhaust Gas Recirculation) valve across any of its generations, from the original E30 M3 through to the current G80 M3. All M3 engines, whether naturally aspirated (like the S14, S50, S52, S65) or turbocharged (S55, S58), are high-performance units tuned for maximum output, and BMW omits the EGR system on these engines to avoid any restriction or contamination of the intake. If you're seeing an EGR-related fault code or part number, you may be confusing the M3 with a standard 3 Series (such as a 320d or 330d) which does use EGR valves on its diesel engines — double-check your registration and the exact model before ordering anything.

Almost certainly yes — no M3 variant sold in the UK has ever been equipped with an EGR valve, so any quote for this part against a genuine M3 is likely the result of a data error or a mix-up with a standard 3 Series diesel. It's worth checking whether your vehicle is registered as an M3 or a 3 Series with an M Sport trim package, as the latter (for example a 320d M Sport) is a completely different car and does use EGR valves on its diesel engine. Contact the breaker with your full registration to confirm exactly which engine code your car has before proceeding.

The question doesn't apply in practice — the M3 doesn't have an EGR valve fitment point at all, so there is nothing for a 3 Series EGR valve to connect to on an M3 engine. The M3 uses entirely different engine families (S-series) compared to the N and B-series engines found in standard 3 Series models. If you do have a standard 3 Series with M Sport trim, trim level makes no difference to EGR valve fitment — what matters is the engine code and emissions generation, so confirm those details with your breaker.

On an M3, emissions or exhaust-related faults are more likely to point towards components such as the catalytic converter, oxygen (lambda) sensors, or — on the turbocharged S55 and S58 engines found in the F80 and G80 M3 — charge-pipe or intake system components rather than an EGR valve. Catalytic converter interchange specifics are something you should confirm directly with the breaker against your registration, as fitment depends on engine code and emissions era. Give your breaker your full registration number and describe the fault so they can identify the correct part for your specific M3 generation.
