Panoramic Part Number Help (Repair Kit)

[AlfaMale]

The lovely UK main dealers who have a monopoly on the situation want to charge me the princely sum of £1700 for the Panoramic Sunroof cassette, excluding glass and motor in case you wondered but does include a complete new roof lining.

Needless to say I'm not prepared to pay this and the roof will remain broken and closed forever.

However IIRC a helpful forum member on here made reference to a BMW repair kit that's available for the common Panoramic Sunroof failure, does anyone know if this is correct and ideally provide me with a part number for this item???

I would be eternally grateful, as I do not want to give up on this..........
