Problems after jump starting

[crvfr]

Couldn't start my almost new (picked up 5 weeks ago!) Z4 yesterday, so had to jump start it from my other car. Used the correct procedure as per the manual, but after starting the Z the following do not work - AC, heated rear screen, manual fan - everything else seems OK. Any ideas what might be the cause before it goes back to the dealer? I spent some time this morning taking out each & every fuse to check them & all OK (couldn't get the big fuses out at the top of the fuse box) and also searched this forum.

Sounds like another fuse to me TBH, but best getting it back to the dealer for a quick once-over anyway.

i hope u left the engine running for a bit to give the battery some charge. when i jump started my car the other time, i had to leave it for 5 mins before all the error lights went off, the electronic rack started working, and the air con coming back on.

Took it back to the dealer today. Apparently as the battery had become so flat (standing around in the dealers!) the car had reverted to 'transportation mode' where the heavy consumers (AC, heated rear window etc.) are immobilised. Anyway, they fitted me with a brand new battery, re-set the car & everything is now OK. Although the car was unused, it was a pre-reg from December and had been standing at the dealers 'till I bought it in February.

Thanks for the follow-up! Nice info to have, if I ever see this problem reported again.
