Known BMW 2 Series faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
01S55 Main Bearing Wear at High Mileage (M2 F87 — High-Revving Use)
CriticalOccasionalEngine $12,000–$35,000 to fix
The S55 3.0-litre twin-turbocharged inline-six in the M2 (and M3/M4) is a high-performance engine that requires meticulous oil maintenance. Main bearing wear is documented at high mileages on vehicles that have been used hard or tracked, especially where oil-change intervals were stretched. The S55 crankshaft main bearings are relatively thin and the engine runs high oil temperatures under spirited driving. Bearing knock at cold start or under load is the primary symptom. This fault is well-documented on international M2/M3/M4 forums and has resulted in multiple engine rebuilds. BMW did not issue a recall but acknowledged oil degradation accelerates bearing wear in the S55.
Symptoms to notice
Knocking or rumbling from bottom of engine under load
Oil pressure warning light at high mileage, especially when hot
Metallic particles in oil on drain or dipstick inspection
Deep ticking or knocking that worsens with engine temperature
What to check
This is a critical item for any M2 above 100,000 km. Check for documented oil change history using BMW M-approved full synthetic oil at maximum 10,000 km intervals. Inspect oil drain plug area for metallic swarf. Start engine cold and listen for any knocking from the bottom of the engine. Check for any track or competition history. If a workshop inspection is possible: Carry out an oil pressure test.
Where to look: Engine bottom end — crankshaft main bearing journals inside the block
Ask the seller
“What oil-change interval was used — kilometres and type of oil?”
“Has the car been tracked or used on circuit?”
“Has an oil pressure test been done recently?”
“Are there any sounds from the engine under hard acceleration?”
02Oil filter housing gasket leak (N20)
MinorCommonFluid Leaks $350–$1,200 to fix
The N20 engine commonly leaks oil from the oil filter housing gasket, dripping onto the belt and subframe. A frequent and messy leak that can contaminate accessory belts if neglected.
Symptoms to notice
Oil leak on the engine's side
Burning oil smell
Oil on belt and subframe
Low oil level
What to check
Inspect the oil filter housing area and drive belt for oil contamination and check for drips onto the subframe below.
Where to look: Oil filter housing on side of N20 engine
Ask the seller
“Has the oil filter housing gasket been replaced?”
“Any oil leaks or burning smell?”
