What is the 2023 BMW M2 Windows and Sunroof Can Close Without the Digital Key Present (Recall 23V-099) - G87 M2?

NHTSA recall 23V-099 covers 2023 BMW M2 vehicles whose body/comfort-access ECU software permits the power windows and the sunroof to be closed remotely without the Digital Key being present at the vehicle. Because the closing function can be commanded when the authorising device… Repairs typically run $0-$0. Severity: medium.

What is the 2016-2018 BMW M2 N55 Oil Filter Housing Gasket Leak - F87 M2 (2016-2018)?

The N55 oil filter housing bolts to the side of the block and seals with a moulded silicone gasket. Heat cycling hardens and shrinks that gasket, and it starts weeping oil - a leak BMW inline-six owners see across the N52/N54/N55 family, commonly starting from roughly 45,000-60,0… Repairs typically run $400-$1,100. Severity: medium.

What is the 2019-2021 BMW M2 S55 Valve Cover Cracking and Non-Serviceable PCV Diaphragm Failure - M2 Competition/CS?

The S55 in the 2019-2021 M2 Competition and M2 CS uses a plastic valve cover with an integrated, non-serviceable crankcase-ventilation (PCV) diaphragm. Two failures come from the same part. The plastic cover warps or cracks from heat cycling and weeps oil down the back of the hea… Repairs typically run $600-$1,500. Severity: medium.

What is the 2016-2021 BMW M2 Rear Differential Mount Bushing Deterioration Causing Rear-End Clunk - F87 M2?

The F87 M2 carries its rear differential on rubber-bonded mounts that BMW specified for comfort rather than the torque the M2 makes. The bonded rubber separates from the metal sleeve, letting the differential move under load reversal. The signature symptom is a hard clunk or clic… Repairs typically run $400-$1,200. Severity: medium.

What is the 2016-2018 BMW M2 N55 Plastic Charge Pipe Cracking / Blowing Off Under Boost - F87 M2?

The 2016-2018 F87 M2 uses the N55B30T0 turbo inline-six, whose charge pipe (the boost tube from the intercooler outlet to the throttle body) is molded plastic. Under repeated boost cycling and underhood heat the plastic embrittles and either cracks at the elbow or blows the quick… Repairs typically run $250-$700. Severity: medium.
