What’s wrong
The affected vehicles may be equipped with a crankshaft sensor with a software fault. The crankshaft sensor cannot process the signal values from the crankshaft transmitter due to an improper firmware level. The firmware does not compensate sufficiently the temperature gradients and the magnetic field strength of the sensor electronic. If the crankshaft sensor cannot process the signal values from the transmitter the Digital Diesel Electronic (DDE) will notice that and change to the emergency operation mode. The emergency mode will be displayed by the check control message �engine malfunction�. The driver may notice a rough running engine and a reduced driving power (70%). However an engine stalling during driving conditions cannot be excluded.
The fix
On the affected vehicles the crankshaft sensor will be replaced with a new version.
