The Air Bag Light on my wife's 00 ML430 comes on occasionally. Here is what I am told.

"After I have been driving for about ten minutes it blinks on and off a few times, then it stays lit for 20-30 seconds and repeats the process over and over."

Any suggestions? Thank you

 

Just a wild guess. Passenger seat sensor or possibly the isofix sensor if you have these in the USA.

Do you place anything on the seat that might be compounding the problem?
