C200 Coupe vibration when on HOLD
The car is not shaking, if you had a coffee cup it wouldn't be wobbling. It doesn't sound mechanical. No obvious culprits under the hood. Could it be exhaust pipe?
After the car is warm it recedes to be almost inaudible.
In the attached audio file it can be heard, at 0.20 neutral is engaged then back again.
Anyone else had this, or suggestions welcome.
