hi, asking on behalf of my friend who drove a 535I GT A, his front passenger seat belt warning didn't sound when he never put on his seat belt. he bought his car just 5 months ago and it just happened. he said he didn't do anything to the thing but somehow it didn't sound when never put on the seat belt. may i know, how to solve this problem? his driver side got warning sound but not for his front passenger side.
