Because of possible leaks at the crankshaft sealing ring, a new crankshaft sealing ring has been installed in the engines of the vehicles mentioned above since May 17, 2005.

In the event of a complaint or when carrying out engine repair work that involves replacing the crankshaft sealing ring, the new crankshaft sealing ring must always be installed.
