Bearing in mind all of the above posts are more likely, I did in fact have a faulty sensor at one wheel and it sent ESP and BAS into a tailspin.mobeyone - 3/18/2005 4:13 PM
my c320 every now and then gets a bas warning light. Have had this checked and it was nothing and all brakes are fine but when i go over a bump (not all the time) it pops on.. is this a common fault? its a 2000 c320?
thanks for all the above guys!brabus - 3/20/2005 2:55 AM
i had this problem before also. its a very common world wide problem on 01-03 cars. its a faulty wiring loom and the dealership can replace this under warrenty in under an hour.
after that is done, its perfect

Before taking it to dealership (if you are not under warranty), I would check the brake light switch. If the switch is not working perfectly, you get the BAS warning.
Brake light switch is usually located next to your brake pedal. I have not accessed it in my C, but I have worked on it in my wife's SLK. It is a module (about $10 or so), replacing it is very simple and safe. It can be done by anybody who knows how to use a torx screwdriver (the panel under the dashboard has torx screws).mobeyone - 3/20/2005 8:07 AM
