Why are Volkswagen engines noisy?
The sound is a rattle that is heard just after the engine is started. The technical background on this issue is that the timing chain tension has lost its ability to keep the tension and the slack causes the rattle in the engine. Thus, the timing chain may jump, causing the engine not to start.
What causes abnormal engine noises?
Common causes: Improper timing, lean air/fuel ratio, or improper octane. You can prevent detonation by increasing the octane level of your fuel, reducing manifold pressure, enriching the air/fuel mixture, or obstructing the ignition timing.

Why are VW diesels so loud?

Do diesel engines get louder with age?
The diesel engines on older vehicles are often louder, given how much softer the older engines are due to the advances made in technology. The oil, fuel, and insulation of your engine could be improved to allow it to produce fewer sounds.
