Hi,
I just bought a 92 230E manual with only 40k miles on the clock.
The car has a full service record from MB and looks and smells like new. Problem is when I drive at +- 40-50 mph and the engine is just not pulling there is a whinning noise from the rear. As soon as I accelerate or decelerate, the noise dissapears. Could a diff fail at such low milage? Could it be adjusted? What about additives? (Dont really like this option!!!!)
