I have a 2008 330d e91, One thing that's bugged be since having the car is the fact that there is no auto rear wipe in reverse with the front wipers on.
I have just started playing with the coding on my car and seem to be successful so far.
Whilst looking at the jbbe coding I can see the option for rear wiper, however even with the option set to active I still don't get the wipe.
Is there anything else I need to activate to get the wiper to work?
Thanks in advance.
