    Hi I am getting a parasitic draw from my e46 M3. I have narrowed it down to the radio fuse #41. With the fuse in I get .1 amps(100ma) and when I remove the fuse I get around .02amps(20ma). I disconnected the radio and amplifier and the antenna amplifier, but it did not drop the amps. I don't...
