Last weekend I picked up my 2007 BMW Z4 Coupe, and found the heated rear window didn't work, the heating blower was pathetic, and the air con didn't work. A web search brought me to the complicated world of BMW coding and finding that it was in Transport mode.
Well, I'm not about to take it to a dealer when I can do something myself, so after much googling came across the friendly BMW community and all the help I could need!
I fixed it, and I hope the information here can help anyone else who has the issue.
The most difficult thing seemed to get a cable that works, and the software to go with it. I was lucky to come across BM Technics at http://bmtechnic.co.uk/, and they recommended the 'BMW Diagnostic Cable – Black Edition'. This also comes with all the software needed, and worked perfectly.
Installation and fixing was simple, all in all taking only a couple of hours start to finish.
The one bit of advice is don't leave your lights on! I had the lights set to Auto, and after an hour or two of playing the car wouldn't start, which made me think I had bricked the car… Not good after a week. Luckily it was only a flat battery

Some of these steps are I from http://forums.bimmerforums.com/forum/sh ... ?t=1867577, cheers rdl.
Some steps might not be compete, most of this is from memory
• Bought cable and software from http://bmtechnic.co.uk/bmw-diagnostic-c ... k-edition/
• Installed the following software
○ Step 1: USB Cable Driver Software
○ Step 2: INPA / EDIBAS / NCSExpert / WinKFP
○ Step 5: VMWare Player
○ Step 6: BMW DIS / GT1
• Started up BMW DIS, and waited for the main screen to appear.
• Easy-DIS said it was v1.0 - base 44, which I think is an earlier version than we need. However, on the Diagnosis screen it says DVD 57.0 - 03/2009 so will work with 2007 Z4
• Selected Diagnosis
• Selected series and model of car, and clicked green arrow in bottom right
• When prompted, plugged into ODB-II plug under a small hinged cover under dash on right side if driver side.
• Loaded, run quick test on the modules detected
• When complete, Right arrow to get to the results
• Selected an error and right green arrow
• Found transport mode, selected, right arrow
○ 'After deleting, must clear defect code memories of all modules using quick delete'
• Select delete, right arrow again
• Deleting, please wait
• Finished, left arrow all the way back?
• Selected end, and selected 'quick delete'
• Then terminate
• Car made some noises. Very worrying… but OK
• All done!
Checked, and I now have proper heating - thank god!
Hope this helps someone.
Easter.
