Disadvantages, breakdowns and problems of the M52
The first years used nikasil coating of cylinders and it quickly collapsed
The engine is very afraid of overheating, the cylinder head immediately leads from it and breaks through its gasket
The cause of frequent misfires is usually coked hydraulic lifters.
DISA variable geometry damper can break loose and fall into cylinders
Another weak point is the crankcase ventilation valve membrane
After 100 km of run, the Vanos phase control system often needs to be repaired
On a run of 200 km, an oil burn often begins due to stuck piston rings
