Error messages on the 2005 E65 FL, need help

Moin meine lieben, I have two questions about two error messages that my fat guy spits out. That would be first of all: ” Brake pads run off, let the next BMW partner check ” The brakes Eights are still top in shot, however, and certainly all – but not awesome. The message came immediately after I had the ‘rest time’ of the brake rear reset, just like service, DPF and Co. (Reset via instrument cluster in the tacho) Does anyone have any idea why they are complaining? I should be put back to the service, and not by immediate request!? Second error message would be: ” Driver restraint system disturbed – belt strapper or belt strap limiter disturbed. Despite disturbance put belt on. From the next BMW service check ” Here I am now totally clueless. The previous owner said it was the seat detection mat – but I don’t believe that. Does anyone have any idea, maybe it happens more often?! Greeting Sven
