W164 320 Bluetec 09 / Air sound from the hood when the engine is hot
My ML 320 Bluetec has air sounds, like air blows under the high pressure when it is hot. I've been with the dealers and they have no idea what it is.
Very big (air intake) sound is heard during deceleration after I drive it in a traffic.
Did someone experienced it and could you please help me with it? It seems like turbo is working when it should not... air sound comes from holes for air.
Thank you
