Only had the car a couple of weeks and the 2nd light has come on!! Started with the airbag light coming on- local indie plugged in and no faults were shown!! Now the missus has just got home saying the seatbelt warning and annoying bong bong noise is going crazy!!

Looks like I need to find a BMW specialist !! Any ideas on solving this problem??

 

Anything caught under the seat that's damaged one of the connectors or wiring?

 

Besides checking wires visually, IMO get a code reader for starters if you want to troubleshoot since it sounds electrical and hopefully there'll be a code.
