Even now, the diesel clatter is obvious and announces it's arrival the moment the engine is started. However, the real test is inside the cabin and this is the area where the bmw shines. once the car is at normal operating temperature, the 'noise' is simply a faint chatter at idle speeds but totally negligible at 1k+ rpm and above.
Once u depress the accelerator, the noise is substituted by pure unadulterated driving joy.
My friend claims that using bhp petrol reduces the engine noise but hv yet to try this since I m on caltex so far.
U can further reduce cabin noise with after market sound proofing around the wheel arches and inside bonnet if u wish.

Malaysia's Euro 2M diesel is not even 2 years old yet today so no car has used it for 2 years. Again how can you know for sure?

You can also try Desmond of KL Auto at Jln Ipoh. He has some light materials by 3M etc but dont get conned by his Autofoam yabba dabba. It's expensive and totally useless as a sound proofing solution. The tighter handling con job of autofoam is also suspect. Stick with old fashion stuff. He has a decibel meter, take a ride with him and he will use it to check where the sound is originating most. Work on those areas.
I have not done it for my 320d yet as I am ok with faint clatter so far.

docrayboy;626843 said:The turbine whirl of the 320d engine, one UK motoring journalist said, is very addictive! Actually the problem with the 320d is that the engine's too quiet. It's a quiet performer, almost as quiet as an electric car. It's like a submarine, runs silent , runs deep. Like Mark Zuckerberg working hard at his Fcebook codes into the depths of the night....then bang!..he's a billionaire.You guys did the right thing...the 320d...the prized treasure, your most coveted motoring possesion.....!

JediM;627571 said:You know what doc, I've been listening out for it, and it just isn't there in my vehicle. The effects of the turbocharger are very real, but the whine just isn't discernible. It was there in my GTI, Subaru, and even Landcruiser 80 series turbo-diesel, but but but....
