Computer restart - now locked out of the boot

[salaro]

Hi

I would be really grateful for any solution. I have done extensive search and nothing showing up.

My wife left the lights on and killed the battery. I jump started the car - but the computer went dead.

I knew that I have to disconnect the batter and reconnect to reboot the computer.

However, May be I did not do it long enough (5 minutes - Apparently I need to give it one hour minimum) so as the result number of electrical components like central locking, air suspension and some more.

The problem is that because Central Locking is not working – windows are open and here in UK it looks it is going to rain tonight - I am now unable to open the tailgate to get into the battery and disconnect and reconnect.

Question - is there a manual method of opening the tailgate. I would have thought this is essential and not something that clever Germans would forget to put.


Or alternatively - Can one disconnect the battery from the engine compartment as I can still access the engine area.
