On the 2016-2018 BMW M2 N55, 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.

This issue also affects: BMW 1 Series, BMW 2 Series, BMW 5 Series

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.

Typical repair cost:$2,500 - $4,500

On the 2016-2018 BMW M2 N55B30T0, 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 45,000-60,000 miles. On the M2 it is significant beyond the mess: the housing sits above the accessory belt path, and oil contaminating the serpentine belt is the documented precursor to the N5x belt-ingestion failure, where a shredded belt is pulled past the front crank seal into the timing case. That turns a few-hundred-dollar gasket job into an engine-out repair. This is an F87 N55 issue; the S55 (M2 Competition/CS) has a different arrangement and is instead known for valve-cover leaks.

Common Symptoms

  • Oil drips or spots under the front of the car
  • Burning oil smell after driving
  • Oil residue around the base of the oil filter housing
  • Oil on the serpentine belt, alternator or belt tensioner
  • Low oil level warning between services

How to Fix

Replace the oil filter housing gasket (and the oil cooler line seals while the housing is off). Inspect the serpentine belt and the front crank seal for oil contamination at the same time and replace the belt if it is oil-soaked - that is the step that prevents the catastrophic version of this failure. No recall exists; this is a customer-pay repair outside the 4yr/50k warranty.

Typical repair cost:$400 - $1,100

On the 2016-2018 BMW M2 N55B30T0, 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-disconnect coupler off entirely. On the M2 forums this is treated as a when-not-if item, and it happens more or less immediately once the car is tuned or running higher boost. The failure is instant and total: all boost pressure vents to atmosphere, the DME throws underboost/charge-air-pressure faults and puts the car in reduced power. It is not a safety recall item and BMW replaces it with the same plastic part under warranty.

This issue also affects: BMW 1 Series, BMW 3 Series, BMW 2 Series

Common Symptoms

  • Sudden total loss of power under acceleration
  • Loud whoosh or pop from the engine bay followed by limp mode
  • Engine malfunction / reduced power warning
  • Boost gauge reads zero under throttle
  • Rough running and loud induction noise

How to Fix

Replace the charge pipe. The OEM plastic part is a like-for-like repair (roughly $150-250 in parts) and will eventually fail again; the community-standard fix is an aluminium or reinforced-silicone charge pipe with a locking coupler, which is a permanent cure. Inspect the intercooler-side coupler and the diverter-valve hose at the same time. There is no recall and no free remedy - this is a wear/design item, so out-of-warranty cars pay for it.

On the 2016 BMW M2 N55 3.0L turbo I6, bMW SIB 12 17 16 defines an F87 M2 path for vehicles produced through August 3, 2016 when a Drivetrain Malfunction message, reduced power and DME faults 120208 and 120408 occur. BMW identifies an overly sensitive DME diagnostic threshold that can switch off turbocharging-pressure control. The bulletin does not establish a cracked plastic charge pipe.

This issue also affects: BMW X3 M

Common Symptoms

  • Drivetrain Malfunction Check Control message
  • Reduced engine power
  • DME fault 120208
  • DME fault 120408

How to Fix

Read the DME faults with the current BMW ISTA version and confirm the production date. If the vehicle meets SIB 12 17 16, program the vehicle to integration level F020-16-07-504 or higher. Do not replace a charge pipe from this card. ShowMeTheParts resolves exact 2016 M2 turbocharger and 3.0-liter fitment but returned no charge-pipe candidate; even a catalog match would not prove the BMW software fault or repair role.

On the 2016-2021 BMW M2, 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.

This issue also affects: BMW 3 Series, BMW 6 Series, BMW M5

Common Symptoms

  • Harsh or delayed shifts
  • Transmission malfunction warning
  • Failure to engage gear
  • Grinding noise during shifts
  • Limp mode activation
  • Check engine light
  • Jerking at low speeds

How to Fix

Replace or rebuild the mechatronics unit. In some cases, a transmission adaptation reset via ISTA can resolve early-stage symptoms. Severe cases require full mechatronics replacement, which involves dropping the transmission. Fluid change every 30k miles helps extend life.

On the 2016-2020 BMW M2, 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.

This issue also affects: BMW 3 Series, BMW 6 Series, BMW M5

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.

On the 2016-2018 BMW M2 N55B30T0, the N55 uses an electrically driven coolant pump rather than a belt-driven one, and its brushless motor/control electronics are a known wear item across the N54/N55 family, most commonly between roughly 60,000 and 80,000 miles. When it fails there is no gradual warning - coolant circulation stops and the engine can reach overheat temperature within minutes of the warning appearing. The characteristic fault codes are 2E81 (electric coolant pump speed deviation) and 2E82 (electric coolant pump shutoff). The pump and the thermostat share the same housing location on the N55, so a pump failure frequently damages or disturbs the thermostat as well. This is distinct from the F87's track-use cooling capacity issue: this is an outright component failure that happens on street-driven cars.

This issue also affects: BMW 1 Series, BMW 2 Series, BMW 5 Series

Common Symptoms

  • Rapid engine overheating with little or no warning
  • Coolant temperature warning and reduced power
  • Heater blows cold at idle
  • Coolant pump audibly silent with the ignition on
  • Drivetrain malfunction message

How to Fix

Replace the electric coolant pump, and replace the thermostat at the same time since it shares the mounting location and the labour. Use a genuine BMW or OE-supplier pump - aftermarket units have a poor service record here. The cooling system must be vacuum-filled and properly bled afterwards or an air pocket will cause a false overheat. Budget roughly $390-450 for the OEM pump plus around $500 labour. No recall; treat it as preventive maintenance around 70,000-80,000 miles if you track the car.

On the 2016-2020 BMW M2 S55, 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.

This issue also affects: BMW M3, BMW M4

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.

On the 2016-2021 BMW 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 click from the rear when shifting between reverse and drive, when getting on and off the throttle, or at low-speed manoeuvring, sometimes with a droning vibration at cruise. BMW addressed the complaint through service information rather than a recall, and NHTSA holds a bulletin covering knocking noise and vibration/droning from the rear axle with instructions to replace the rear differential suspension mount. The complaint appears on both manual and DCT cars and is aggravated by track use and tuning.

Common Symptoms

  • Clunk or click from the rear when shifting reverse to drive
  • Knock from the rear axle on throttle on/off transitions
  • Droning or vibration from the rear at cruising speed
  • Rear-end looseness felt through the seat during hard launches

How to Fix

Inspect the differential mounts and the rear subframe bushings before chasing the noise elsewhere - a failing exhaust hanger or a worn driveshaft flex disc produces a similar clunk. Replace the rear differential suspension mount per BMW's service instructions. Many owners fit polyurethane or aluminium-insert mounts, which cures the clunk permanently at the cost of some added driveline noise into the cabin. Cars still under the BMW new-vehicle warranty have had this covered; there is no recall.
