Hello, just after some quick advice.

MOT flagged up a problem with the rear centre seatbelt, I've had problems with it beforehand as it has tightened up into the seat and can no longer be used. Official line on MOT was the retainer had failed.

There is a seatbelt available on ebay which appears to be the full unit.

They have listed its part number as 8E0857713


1. Is this full unit likely to include the retainer? I'm assuming it is!
2. Is the part number identifiable anywhere on the unit?
3. Any differences between Avant and Saloon models?

Hope I've put this in the right place for answer, apologies if not, and thanks for any help forthcoming!
