I am trying to determine what the latest version of sw for a E39 540i6 (08/99) is.
The local dealer indicates there is no new sw - but I get the sense they are not quite interested in checking.
Can anyone shed any light on the subject of sw for E39/540i6 (08/99)?
I am specifically looking for answers to the following questions:
- What is the latest rev for an E39 540i6?
- What are the improvements over the prior revs?
- How can one check to see what rev is installed in the car?
