I notice the 2008+ ML320 CDI has a very quiet engine.
When idle, it is almost as quiet as the gasoline is. (even quieter in the cabin)
Is this just because the engine is very new (less than 2 yr) ? or these newer diesel engine are indeed designed & made to be quieter?
I am trying to find out if ML's diesel engine will become a loud with strong vibration down the road … say 5 yrs later.
if anyone can shed some light, I would greatly appreciate it.
