I have in a 2005 e46 m3 smg. The left hand main beam just stays on regardless of ignition being on or off. Any ideas. Also the car came in not running after someone tried fitting some audio gear. The ignition was not even coming on. I have tested at the ignition barrel and the red/green wire which should be 12volts positive was dead. The red/blue was live. I jumped the 2 together and voila, the car starts. Where is the fuse for this red/green wire as i cannot find one blown anywhere. And is the beam being on something to do with me joining the red/green to the red/blue. All advise appreciated guys.
