October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Component Tests: Notes

NOTE: Before disconnecting the control unit or the battery, use BMW tester and read out the defect code memory and print out with troubleshooting. Detach control unit connector only when the ignition is off. Check wires only with the control unit connector or component connector detached.
