Used BMW M4 EGR Valve

No — the BMW M4 has never been fitted with an EGR (Exhaust Gas Recirculation) valve. The M4 uses high-performance petrol engines (the S55 twin-turbo straight-six in the F82 generation and the S58 twin-turbo straight-six in the G82 generation) that are not equipped with EGR systems, as BMW's M division tunes these engines for maximum performance without the emissions-management compromises that EGR valves involve. If your BMW is throwing an EGR-related fault code or you need an EGR valve, you may be looking at a different BMW model — the 3 Series or 5 Series diesel variants, for example, commonly carry EGR valves and are worth searching for instead.

Almost certainly not — no variant of the BMW M4, across either the F82 (2014–2020) or G82 (2021-onwards) generations, was ever fitted with an EGR valve, as all M4 engines are petrol units that do not use exhaust gas recirculation. If a parts supplier has quoted you an EGR valve against your M4 registration, it is worth double-checking whether there has been a data error or a mix-up with another BMW model on your account. You may want to contact a breaker directly and confirm the exact part you need, as the fault or symptom you are experiencing is likely caused by a different component entirely.

Yes — since the M4 does not have an EGR valve, an EGR-related fault code appearing on an M4 is unusual and may point to a wiring fault, a diagnostic software error, or a misread of the vehicle's identity by the scan tool. It is also possible the code has been retrieved from a different BMW that shares a diagnostic port session, or that the code description has been confused with another emissions-related component such as a VANOS actuator or throttle body. We would recommend having the fault code verified by a BMW specialist or independent garage before searching for parts.

The BMW M4 petrol engine does use a catalytic converter and, depending on generation and market, may also use a petrol particulate filter (PPF) — these are the emissions components present on this model rather than an EGR valve. If you are sourcing a used catalytic converter or particulate filter for an M4, engine code and emissions era (Euro 6 compliance in particular) are the critical fitment factors, and you should confirm exact interchange compatibility with the breaker against your registration. Trim level — whether Competition, CS, or CSL — does not affect which emissions system the car uses, as fitment follows the engine and emissions legislation of the build year.

Trim level does not determine emissions fitment on the M4 — what matters is the engine code (S55 in the F82 generation, S58 in the G82 generation) and the emissions standard the car was built to, typically Euro 6 for later cars. The Competition and CS models share the same fundamental engine architecture within their respective generations, so any exhaust or emissions component sourced from a breaker should be matched to engine code and build year rather than trim badge. Always confirm the specific part number with the breaker against your full registration to account for any mid-production running changes.
