Sunroof Problems !!!!

Hi All
Today, I drove around to my Dad's, got there, parked up and removed the key from the ignition and then heard a noise which I now know to be the sunroof motor. Pulled back the interior cover for the sunroof and my sunroof was opening and closing on it's own ( In the tilt position !) It done this anout four times. What I did was put the key back into the ignition, started her and then switched off which seemed to cure the immediate problem. The rest of my journeys today have been problem free.
My main worry is that it might decide to open in the middle of the night when there will probably be rain.
I contacted an ex VW tech and he said that as long as the sunroof is in the closed position when the car door is being locked, it shouldnt open on it's own.
Please help !!!

PS. The car is a MK4 1.6s 16v (with sunroof), 2001 4DR

Never hear that one before. With the ignition off it should not do that so I think you will be OK but keep an eye on it.

Hi
The thing is Crasher, it was when I took the key out of the ignition that it happened. I am not a mechanic or anything, but i thought it may have been something to do with the comfort module ( CCM ) ??? I am not sure if this covers the sunroof. With me swithing it on and back off again, seemed to cure it hopefully ( fingers crossed )

The convenience system is only responsible for sunroof total closure when the ignition is off. The conv unit on the Golf 4 is very reliable until it gets wet so unless you have had water appear on the driver’s floor I think the conv unit itself should be OK. As I said, I have never known a sunroof do what you describe. Possibly a fault code read of the convenience unit would show an issue, possibly showing code

Hi
Checked the footwells this-morning and no signs of water or dampness.
The sunroof hasn't behaved like that again since yesterday.
Have the 3m tape and plastic sheeting on standby.
Thanks for the reply
