So I was out driving last week and it was pretty nice out so I turned off the ventilation system and rolled the windows down and opened the roof. A few minutes later the A/C was on again so I thought that I may have accidentally touched a knob and so I turned the ventilation off again, only to have it mysteriously turn on again a few moments later. I turned it off again and it turned on a minute later, this process repeated quite a few times and since then has been happenning almost daily. I've called the dealer and scheduled an appointment for next Friday. Has anyone else experienced the phantom ventilation?

 

Happens to my 04 545i all the time, not sure what the deal is but keep us posted. It drives me crazy

 

It happens to me every once in a while also. I don't know what's going on.

 

condensation senser i think..

 

yea mine is doin the same thing it pisses me off... PLS ANSWERSS

 

seemingly only 04's and 05's appear to have this "glitch". How many of you have AiB's? Just curious I was reading another thread that states it can emit EMI's that will interfere with other electricals.
