Hello all I am new here looks like a great bunch sharing information.
I have a 2001 740iL and have an intermittent problem in the starting circuit.
Symptom: Turn the key, instrument panel lights, steering moves into place, all normal. Trun the key and sometime is starts, sometimes it doesn't. By not starting I mean the starter does not pull in, just a single relay click (control relay?) the solinoid is not clicking.
When I replaced the battery the car started fine. The next day we were going to use it and it wouldn't turn over.
Then the next day it started fine, took it to the store. Came out didnt start. Then tried again and it started normally. Drove it the next three days in a row, no problems. Parked it and it has not started since. Of course it will leave me stranded one day if I continue to tempt fate.
A little more history. It is not a daily driver, 33000 miles. Usually eats a battery every 18 months to two years. I replaced the battery with a fresh one two weeks ago and have even added a battery maintainer.
There are no error messages being thrown. I am confident that there is pleny of cranking power available to the circuit.
Any ideas? Thanks in advance for any ideas on what to look at.
