Is there a proper way (procedure) to disconnecting a battery in order to clear error codes on my 2000 540? Will any reprogramming be required after this?
Disconnect Battery to clear codes applies only to vehicles 1995 and earlier. For 1996 and later models u need to clear the codes with a scanner. If u are in the U.S. Autozone can read and clear your codes for free... :)
