well its my bosses truck and the service engine soon light is on... it beeps 5 beeps at 5 intervals... is this some kinda code? it started right after he had the brake master cylinder changed... not sure what code is in there or if there is a code... my X3 is at home... does anyone know anything about this?

 

is this something to do with the air bag sensor?

 

mods please delete, i put it in the wrong section... sorry!
