Engine Overview and Common Failures
The CBAB engine number is located at the front junction with the gearbox. The oil pump hexagon is integrated with the balance block in this power unit, which is driven by a very short hexagon. It tends to wear out around 150,000 km, causing the oil pump to disengage and reducing lubrication pressure in the system. In November 2009, the length of the problematic hexagon was increased, solving this issue. The fuel system, Bosch CP4, is considered very reliable, but it does have weak points. Improper maintenance can cause the roller tappet of the fuel injection pump to rotate perpendicular to the cam, resulting in metal shavings being pumped into the system. The fuel pressure regulator also regularly gets stuck, and the use of low-quality diesel immediately affects the lifespan of the piezo injectors. As for the turbocharger, the KKK BV43, also known as BorgWarner, is not problematic itself. However, its vacuum actuator for variable geometry sometimes experiences membrane cracking. The control valve of the turbocharger may also fail or its vacuum tube may rupture. Like any modern diesel engine, there are other issues such as EGR valve and intake manifold swirl flaps getting clogged, with their mechanisms being not particularly reliable. The membrane of the oil separator in the valve cover also needs regular replacement.
