What is the 2016-2021 BMW M2 DCT (M-DCT) Mechatronics Unit Failure?

The 7-speed M-DCT dual-clutch transmission in F87 M2 models can develop mechatronics unit failures, causing harsh shifting, failure to engage gears, or transmission fault warnings. The issue is related to the solenoid pack and hydraulic valve body within the mechatronics sleeve. Repairs typically run $2,500-$6,000. Severity: high.

What is the 2019-2020 BMW M2 S55 Crank Hub Failure (CATASTROPHIC) - M2 Competition?

The M2 Competition shares the S55 engine with M3/M4 and inherits the catastrophic crank hub failure issue. The crank hub (harmonic balancer) is press-fit onto the crankshaft and can slip under high load, especially with upgraded software or track use. When the hub slips, timing i… Repairs typically run $1,200-$2,500. Severity: high.

What is the 2019-2021 BMW M2 Missing Fuel Injector Damping Element Causing Fuel Rail Leak (Recall 20V-666) - M2 Competition?

NHTSA recall 20V-666 covers 2019-2021 F87 M2 Competition and 2020 M4 coupes built after BMW relocated part of the engine assembly line. Before the move, the damping element on each fuel injector was fitted by an automated process; afterwards it was fitted manually, and on some en… Repairs typically run $0-$0. Severity: high.

What is the 2019-2020 BMW M2 Improperly Folded Knee Airbag May Not Deploy (Recall 19V-352) - 2019-2020 M2 Competition?

NHTSA recall 19V-352 covers 2019-2020 BMW M2 (M2 Competition) among other M models. The knee airbag module was improperly folded and assembled at the supplier, so in a crash where the knee airbag is commanded to fire it may not deploy as intended, reducing lower-body occupant pro… Repairs typically run $0-$0. Severity: high.

What is the 2016-2020 BMW M2 DCT Dual-Clutch Transmission Shudder & Clutch Wear - F87 M2/M2C?

The Getrag DCT (dual-clutch transmission) in the M2 and M2 Competition experiences clutch pack wear from aggressive driving, launches, and track use. The DCT has two clutches (odd and even gears) that wear over time. Symptoms include shuddering during low-speed acceleration, roug… Repairs typically run $5,000-$8,000. Severity: medium.

What is the 2016-2020 BMW M2 Cooling System Inadequacy Under Track Use - F87 M2/M2C?

The F87 M2 and M2 Competition have marginal cooling capacity for sustained track use. The small grilles and compact engine bay restrict airflow to the radiator, oil cooler, and intercooler. On track, oil temperatures commonly exceed 280°F and coolant temperatures spike, leading t… Repairs typically run $2,500-$5,000. 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.
