Hi all, and thanks in advance.. Many BMWs but this is my first Z4. I just purchased an 03 which had been severely neglected... but runs drives like new. Need help diagnosing this one..
No turn signals inside .. all outside working
No audio from radio/CD
Air bag light on
Other random lights on then off.
Top works randomly
Sometimes when shutting down and removing key, beep continues as if key remains
High/low beam indicator rarely works
AC fan and inside controls appear to work properly but compressor does not engage
Only 1 code found P0700, cleared and stayed off for several days, returned and cleared again.
It appears they replace a battery within a last year.
All fuses check good
12.2 v when off 13.5 when running
I have read hundreds of posts similar but none matching.
Does not appear to be low voltage ??
No "seen" corrosion.. ?
Help is much appreciated!
