It's elementary. Be it petrol or diesel engines, noise will increase with age. Belts, valve tappets, bearings and other wear and tear components. 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.

for my previous rides, I have tried KK Lau audio in PJ - they use dynamat extreme, which is rather heavy.
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.

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.....!

From the inside when its on the move, its quiet in the sense that you dont hear the revs of the engine....which actually is NOT a good thing...but you do get the addictive turbine whirl in lieu which IS a good thing.
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....

Its a soft low pitch whirl....not very obvious......that's the real problem with the 320d - its definitely NOT noisy like everybody always hantam us...we wished there was MORE noise, especially when we hit the high speeds/revs....but its a quiet performer. sometimes boring...until the tail comes out....oppps baby, DTC save me!!!!
