Disadvantages, breakdowns and problems of BDH
Most of the problems for owners are caused by malfunctions in the capricious VP44 injection pump
Updated hollow camshafts often burst on runs of 150 - 250 thousand km
Also, grease constantly oozes from the joints of the motor and from under the valve covers.
In the turbine, the geometry mechanism often wedges, the viscous coupling bearing does not last long
From low-quality oils, hydraulic lifters and pressure reducing valves can seize.
