[IBIZA 6K] The sunroof suddenly operates automatically...

Hi,

I'm having a problem with my Ibiza 6K 2000... The sunroof has the usual VW control for tilting/raising...

And for some time now, it's been acting up on its own, sometimes running sluggishly while driving, not always due to vibrations or anything else, and not always reproducible...

It usually goes back to normal again.

The potentiometer for the sunroof actuator is the same as that of the Golf IV...

Ideas?

Regards,
Georg
