Exactly! This is happening in all professions, whether you are a car mechanic or an eye surgeon! My VW new Beetle’s air bag light when on many years ago. In those days my ODB reader could not be used for checking the air bag codes or resetting it. Dealer scans it and says it needs a new air bag for the side of the drivers seat, new harness, second ODB test, and the bill is just under $2 thousand CDN dollars. So I say...what caused this, because there are 5 more air bags and the car is several years old. Answer “age”. So I again say, excuse me , but you don’t hear of air bags becoming defective do you? Not satisfied, went back to my original dealer where purchased, explain the situation, pay for another scan. Result-harness goes under seat and with movement wires got pulled. Cut, spliced, taped, good to go. I go back to 1st shop and explain the result and ask to speak to the mechanic, who is in his early 20’s. I ask him...did you inspect the wiring? Answer, no! ODB code read it was a bad air bag, you need a new one! I told the manager- refund what I paid for the diagnostic charges, and sit down with your mechanic and explain what an ODB reader does and does not do.
