Engine Software Update on W211 420CDI 2008
There has been a request from Mercedes factory to update the engine software.
The work code is 1105P54B24
As far as I know engines involved are: on models 164, 204, 207,and 212 with engine OM642.8 and models 211 and 221 with engine OM629.
Does any body know what changes/ functionalities are affected by this update?
In advance many thanks
