Is my new Z4 in transport mode after jump start?

Yesterday I picked up a 2004 3.0 Z4 in Germany and had to drive 1100 km back to Denmark where I live. The car had been sitting all winter in a garage with no power on the battery. Owner jump started it and everything worked just fine when it came alive. I test drove the car, went through everything and went inside afterwards to do the paper work. 30 min. later I started the car and everything was still ok. Then I drove for like 5 hours on the autobahn and stopped to get a couple hours sleep. When I tried to start the car again it was completely dead. I jump started it again from another car and the engine fired up straight away - but now the satnav and all the gauges where out - lights, AC, cruise control, radio and so on worked just fine but it was really frustrating to drive in the night without any fuel gauge, speedo and so on. Good thing there are no speed limits in Germany :D

Anyways - the battery is obviously dead and needs replacement but do I need to worry about the electical problems I had? I've read about transport mode but not resulting in the same electrical problems I have.
 
Worst case I would say us that it's gone into transport mode. Get a new battery on though and you might be lucky and find that's all it needs.
 
When i bought my Z it had suffered a run down battery & was in transport mode . Basically meant the AC was out of action along with rear heated window .
Everything else worked as normal
It,s as simple procedure to re-set but need,s the correct diagnostic gadget to do it

Same here, Transport mode only effected heated rear window and fan speed and A?/C wasn't working.
I'm presuming the battery is dead and effecting the electrics due to lack of amperage, so may things are shutting down.
