The roof on my Z4 came down in the middle of the night, i was greeted in the morning by a car with both the roof and the windows down and the car slowly filling up with rain water, the dealer ran a diagnostic that revealed nothing, other than a bill for 120 pound!...anyone had this happen to them
 
the widows do funny things sometimes but only when they are going up or down and you open a door or something. the roof needs you to hold the button, key etc.for the whole operation. You didn't just brak up with you wife did you? :?

haha, yeah she was jealous of the car getting all of the attention


it would be a good function on a summers morning, not in rain though!
 
Who drove the car last?

Are you SURE the top was up?

If you hold the button, the windows will return back up after the roof operation finishes, so if they were down, seems to me like it was being drivin with roof and windows down.

Not always true, mine don't. Me and the Indi tried to work this out for ages and gave up.

Same as when I put the roof down, they drop fully instead of 2inches or whatever.

Ahh, well mine only go half way down... Seems they changed the software somewhere along the line.
 
My car is a 58 plate 2.0i and about three weeks ago I came out of the house to go to work and found the roof down on the car. I assumed that someone in the house (2 kids) must have touched the keys, though everyone was adamant they hadn't.

This has not happened since

I'm no auto electrician, but I cannot for the life of me see the logic that would allow the electrical system to malfunction in such a manner as to cause this? I mean in order to get the roof completely down, it would (i) have to be a short of some kind that applied current to the roof motor circuit, and (ii) a short that miraculously fixed itself once the roof was down wouldn't it?

As said, when putting roof up, keeping the button held down also puts the windows up after a short pause, while in the opposite direction, the windows shoud stop st the halfway down position....

And alant, if I had a pound for every time my hids were "adamant they hadn't" and had, I'd be a millionaire! LOL Do they know it does roof-down on the key? If they do, I suspect thats your answer....
 
Hi,

I drive a 318 Convertible and I parked it in a car park. When I returned less than an hour later, all the windows were down and the roof was partly on its way down. Needless to say that other drivers in the car park looked at me like I was an idiot, putting my roof down in winter. I 100% know that I never pressed the button, had anything leaning on the button.

I spoke to BMW and asked if this sounded like a familiar problem, they said no and suggested that I bring the car for a diagnostic test. After reading you post, I am glad I didn't.

I live near Glasgow and there has been extremely cold weather, so I don't know if some freak incident has occured in the electrics. Thanks for posting, good to know that it has happened to someone else and that I am not going mad.

Pah.. they're only jealous! Mine was down on the way into work, and it's 1 degree on the clock!



Your case is a more understandable case than the OP.. as you say the roof wasn't down fully.
That sounds much more like an electrical fault, as it may have shorted briefly, allowing the roof to start moving, before unshorting..
I've zero experience with the 1 series (never even sat in one), so haven't a clue really, but maybe it's some condensation on the motor switch terminals?


Yep.. I'm well helpful today!
