🤢 I have a 320 estate, 5 years old. Drivers side front seat belt has been intermittently jamming and can’t be moved/worn

however later it frees and is fine for a week or two. After much cleaning, the garage fitted a new BMW part, the complete belt and fittings,from the main dealer

and a week or so later this jammed also. Has anyone else had this problem and do you know what causes it? Thanks, Rod

Morning Rod

This is a new one on me, seat belts these days tend to be boringly reliable and normally fray not stick, particularly as you have a new OEM part fitted. From memory the inertia reel is bolted to the B pillar base the belt runs up the B pillar through a guide about halfway up then to the height adjuster mechanism then down to it's fixing point on the seat. I would take off the B pillar trim and check its route is clear and that it has been put in correctly.

Have a look at www.realoem.com put the last 7 digits in the search box it will bring up your model check the small drawing for how it's fitted (or should be). I can only think that something is picking up either at the guide or the adjuster as the inertia reel units are pretty much sealed

Hope this helps
