Fella's,
My previous W124 consumed two differentials in a relatively short period of time. I understand the diff on this model was notoriously bad. Ever since I bought my W210 I'm hearing this 'whistling' noise from beneath the car, but several MB shops have assured me that this noise comes from the auto gear box and is normal. (The car was under warranty then, BTW)

Do you know if the W210 has similar diff problems like the W124?

THANKS
