Try this combination and see if it does enter the ENG menu.
If so you have no problems to activate all options.
If not.. try to downgrade the firmware.
Engineering Mode
To enter the engineering Mode do the following:
1) Turn the ignition to on (Note : it works with the car started as well)
2) With the radio playing (Note: it works with other things like DVD playing) press :
a. Press and hold these buttons in this order
Mute – Service – End Call all together and hold for 5 secs (ish)
b. Sometimes this doesn’t work, so simply try again, not sure why it doesn’t
always work, maybe its the order I press them in?
Note : If the key combinations above do not bring you to the engineers menu one of the
following may work on your vehicle:
• MUTE + 3 + 4 +5
• Phone Down + 1 + 3 + 6
• 1+6+4+3
• mute + phone down + serv
• mute + 3 +4 +6
• mute+357
For me worked MUTE+3+4+6
Right now on my BE 7039 I have 2007 installed

BTW.. If the dealer want can give you the firmware if it does not he is in the right to do since I have a dealer as "friend" and the WorkShop CD's are not for sale.
