Woodcliff Lake, NJ December 1989 Technical Dept.
SUBJECT: Whine Through Speakers - CD Equipped Vehicles
MODELS: All so equipped
Situation: Under certain conditions, with the engine running, a whine may be heard through the speakers when the radio is ON (does not have to be in CD mode).
It has been found that if the CD data cable is routed down the left side of the vehicle (versus the right side), this whine can be minimized.
Remedy: Reroute the CD data cable down the left side of the vehicle as per the updated CD installation instructions found in S.I. 65 07 88 (1703) dated November 1989 for the Alpine Systems.
Note: Factory prewired vehicles had this change incorporated on the following dates:
750iL 4/88
735iL 6/88
735i 9/88
535i 3/89
525i 3/89
