Mein Auto: Z4
Z4 Heater/AC Fan

It is winter and we have left the Z set too long in the garage before starting it the other day. Now the fan will not turn on. The last time this happened I took it to the dealer and was told that there is a transport mode which shuts things down when the Z sets too long. Is there a way to turn off the "transport mode" without going back to the dealer? I would just as soon do it myself instead of having to go back to the dealer all the time.

The dealer should have turned off the cars ability to go into transport mode when they "fixed" it the last time. I would go back and ask why they didn't do it correctly. They are supposed to turn the feature off as part of the PDI process, but this is not the case for many Z4 owners. To answer your question you can DIY, but need special software and an OBD cable. I think it is called NCI Expert, but I may have that wrong. I am sure others will chime in. I also recommend a battery tender to keep your charge up during the long winters since you have a garage.
