Hey, did you find any solution for that?
I have the same problem this weekend... still can't figure out how im i going to fix the front slider... (It jumped off).
I'm like "this is a 3 year old bimmer and it happened so easily!" Damn! My old renaul got is air sliders in perfect shape for 15 years... :\
Well can i find it (slider) on sale somewhere?
It has the rear left side broken holder...
Pardon my bad english.
