Hi Jonny,
I have 1998 540i with not start problem. I was able to trace the problem down to the EWS box. If I jump the two black wires at the EWS and turn the key, the car will start. Without jumping the wires, nothing will happen. Once the car start, I noticed that the radio will not power on, but everything else on the radio unit works( BC, clock, etc works). Prior to this no start problem, I get this intermittent problem like the car would break on it own and the ASC light will come on while I'm driving. What do you think the problem is?
