All 6 Known Issues
The N55 engine in the F87 M2 (2016-2018) suffers from accelerated rod bearing wear, though not as catastrophic as the S65 V10. Track use, aggressive driving, and extended oil change intervals accelerate bearing wear. Tight bearing clearances and high cylinder pressures in the M-tuned N55 contribute to the issue. Symptoms typically appear after 60,000-80,000 miles or after multiple track days. Unlike M3/M5, most M2 owners catch this before complete failure, but preventive replacement is strongly recommended for track-driven cars.
Common Symptoms
- Metallic knocking noise at idle (especially when warm)
- Oil pressure fluctuation or low oil pressure warning
- Metal particles visible in oil (send oil sample to Blackstone Labs)
- Engine noise increases with RPM
- Low oil pressure at hot idle (below 14 PSI)
How to Fix
Preventive rod bearing replacement recommended at 60,000 miles or before track use. Upgraded aftermarket bearings (ACL Race, King Racing) provide larger clearances and better durability. Oil analysis every 5,000 miles to monitor bearing wear (check for copper/lead particles). Use high-quality 5W-40 oil (Liqui Moly, Motul) and change every 5,000 miles max for track cars. Some track-focused owners replace bearings every 50,000 miles preventively.

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 is lost and valves contact pistons, destroying the engine. This is the same critical failure point as the F80 M3 and F82 M4. The OEM crank hub has inadequate interference fit. Most failures occur on tuned cars or during hard track use between 30,000-70,000 miles.
Common Symptoms
- Sudden catastrophic engine failure with no warning
- Rough idle or vibration (early warning if hub is starting to slip)
- Check engine light with timing correlation codes (P0016, P0017)
- Misfire codes across all cylinders
- Metal-on-metal noise from front of engine
How to Fix
MANDATORY preventive replacement with upgraded pinned or keyed crank hub. Pure Turbos, VTT, and S55 Crank Hub Fix all sell upgraded solutions with mechanical retention (pin or keyway). Installation requires crankshaft pulley removal and careful torque specs. This is considered essential maintenance for any S55-powered car, especially if tuned or tracked. Many M2 Competition owners perform this upgrade immediately after purchase.

Both the N55 (M2) and S55 (M2 Competition) engines use plastic charge pipes that fail under boost pressure and heat cycles. The charge pipe routes pressurized air from the turbocharger(s) to the engine intake. Plastic becomes brittle and cracks, especially on tuned cars running higher boost. Failure causes sudden loss of power and limp mode. The N55 has a single large charge pipe, while the S55 has multiple boost pipes that can fail. Aftermarket aluminum pipes are considered mandatory for any tuned M2.
Common Symptoms
- Sudden loss of power while driving
- Loud hissing or whooshing sound from engine bay
- Check engine light with boost pressure codes (P0299, P0234)
- Limp mode activation
- Visible crack in plastic charge pipe
- Boost gauge shows loss of pressure (if equipped)
How to Fix
Replace with upgraded aluminum charge pipe. Popular brands: ARM Motorsports, VRSF, BMS (Burger Motorsport). Aluminum pipes eliminate the plastic failure point permanently and support higher boost levels for tuned cars. Install is straightforward DIY. For M2 Competition, also consider upgrading all boost pipes while engine bay is accessible. Many M2 owners install aluminum charge pipes preventively before failure.

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, rough shifting, and slipping under hard acceleration. Track use and repeated launch control engagements accelerate wear. DCT fluid degradation also contributes to poor shift quality. This transmission is shared with M3/M4 and has similar failure patterns.
Common Symptoms
- Shuddering or judder when accelerating from a stop
- Rough or harsh shifting between gears
- Slipping sensation under hard acceleration
- Burning smell from transmission
- Check engine light with transmission codes
- Clutch slip warnings on iDrive
How to Fix
Replace DCT clutch pack ($4,000-6,000 parts + labor). Change DCT fluid every 30,000 miles with BMW-approved fluid to extend clutch life. Avoid excessive launch control use. Transmission adaptation reset via BMW software often improves shift quality temporarily. Some performance shops offer upgraded clutch packs for track use. Extended warranty coverage highly recommended for DCT-equipped M2s.

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 to heat soak and power loss. The M2 Competition with S55 engine runs even hotter. Extended track sessions can cause cooling system component failure or engine damage from overheating. This is well-documented on M2 track forums and affects all F87 M2 models when pushed hard.
Common Symptoms
- Oil temperature exceeding 280°F during track sessions
- Coolant temperature warning on track
- Noticeable power loss after 3-4 hot laps (heat soak)
- Limp mode activation from overheating
- Intercooler heat soak (reduced power on turbocharged models)
- Fan running constantly after track session
How to Fix
Install aftermarket cooling upgrades for track use: CSF radiator (higher core density), aftermarket oil cooler (Mishimoto, CSF), upgraded intercooler (Wagner, CSF), and coolant reroute kit. Remove kidney grille blockage for better airflow. Install oil temperature and pressure gauges to monitor. Limit track sessions to 15-20 minutes with cool-down laps. Many serious track M2 owners install full cooling system upgrades ($2,500-4,000 total). For street use, stock cooling is adequate.

Track-driven M2s (especially with sticky tires and aggressive alignment) can develop cracks in the rear subframe mounting points. The rear subframe holds the differential and rear suspension, and high lateral loads from track driving stress the mounting points. Cracks typically occur at the rear subframe-to-chassis connection points. This is most common on M2 Competition models with stickier tires and more power. Street-driven M2s rarely experience this issue. Symptoms include clunking from the rear, alignment going out of spec, and visible cracks during inspection.
Common Symptoms
- Clunking or banging noise from rear suspension over bumps
- Rear end feels loose or unstable
- Alignment drifts out of spec frequently
- Visible cracks in subframe mounting points (requires lift inspection)
- Abnormal tire wear from shifting alignment
How to Fix
Reinforce rear subframe mounting points with weld-in reinforcement plates before cracks develop. Several companies (Vince Bar, BMW Performance Parts) sell subframe reinforcement kits. Installation requires welding and should be done by experienced chassis specialist. For already-cracked subframes, weld repair and reinforcement is required. Track M2 owners should inspect subframe regularly. This is considered preventive maintenance for serious track cars.
