I have a new... old car...1996 Mercedes E320...gas version. The drive train has a 10-20 over S9 whine that varies with the speed of the car in motion. At rest, no noise. It does not vary with the engine RPMs. Its worse on 75M and barely noticeable on 160 and 40. The only way I can test is on a lift. I have some ideas on how to sniff it out. But would welcome ideas on what the cause is.
I love 75M mobile...but this is a problem.
This car replaced a E300 which got totalled. I heard that same whine in that one too but at a very low level and was never an issue. The same antenna is on this car...an ugly one (but beautiful to me
)
