Having problems with your BMW 325 ?
How do i reset the fault code on a 2001 bmw 325i after the cmp sensor has been replaced?
Unless you have a scan tool you can not reset the faults in a BMW even if the check engine light is out there will still be faults stored in the system you have to have a shop clear the code thats the only way. disconnecting the battery will not help in any way i have been a bmw master technician for 10 years now.
