Seatbelt warning sound stopped

[CliftonH]

Hi guys I need some help please, the other day my seatbelt warning sound started croaking and then it stopped working, The sound seem to be under the steering somewhere, I think its a relay problem, not sure, any ideas on how to fix this,

The reason I want it fixed is that now there is no warning sound for lights, or handbrake up or any warning sound,

please any help will be appreciated,

my car is a 2005 E90 320D

thank you,
