Cooling System Plastic Components:
Expansion tank, thermostat housing, and water pump impeller can become brittle and crack over time, leading to leaks.
Rear Subframe Mounts:
Stress cracks can develop in the sheet metal around the rear subframe mounting points due to chassis flex.
Window Regulators:
Plastic guide pieces in the window regulator mechanisms are prone to breaking, causing windows to fall down.
Oil Pan Gasket Leaks:
Common wear item, often requires replacement due to age and heat.
Vanos Issues:
While less pronounced than in later 6-cylinder engines, early VANOS systems (if equipped on certain M43 variants) can develop issues affecting low-end torque.
Radiator Leaks:
Plastic end tanks of the radiator can crack with age.
