I know that it's kind of a running joke around here that all newbies ask what that noise is, but I can't find the answer. You know the one I mean. What is it?

the noises are a good thing, its when you dont hear them you start worrying.

1. Climate control stepper motors
2. Heater valve solenoids
3. ADV - windshield wiper pressure control motor (The noisiest of them all!)

Thanks for all that.

Funny that my 1986 Toyota Celica also has motorised vents -- and they're barely audible. Dunno why BMW couldn't manage that...

I think the dual zone climate control on the e34 is a lot more sophisticated than your toyota celica, more motors, etc... The celica might also not shut everything when you turn the car off, just a guess but the e34 might shut everything to hold heat/cool in longer and keep smells out. When i first got the car, i was sort of worried and very puzzled at what the strange noise might be, i thought it was the speakers at first.

as pundit said the wiper control is the really noisy one,in behind the dash by the drivers wiper????> i think most cars just shut down and leave all the steppers etc in the same place,not close everything up

I love freaking passangers out when you switch the car off, and a bit later it starts doing its own thing!!

Yes, I've been telling them they're being weighed for ejection.

adv is an electric motor which puts pressure on the drivers wiper.If you have it you have a allen screw on the top of the drivers wiper,as well as the cinch bolt.You will also hear a whine at about 15 km hr when you first start off.You also hear the occasional whine when you operate the wipers or washers at other times
