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.
