Noticed the other day my passenger seat belt warning has stopped working, no chime and no dash light. I've found an A3 thread stating this will not effect the airbags etc so thats one less worry. It has worked in the passed usually noticed when bringing the beer home. Question therefore is there anything I can check as I'm not too worried about getting it sorted as the car still has five months warranty left. Could this in anyway be related to my hazard lights comming on when the car is locked as if the alarm has been activated, are any circuit boards common? Just want to resolve all issues whilst under warranty. Thanks in advance.
