What are the reasons why the Volkswagen CC has power but won't start?

[RachelAnn]

Here are the possible reasons why a Volkswagen CC has power but won't start: 1. Engine washing: Washing the engine may cause water ingress and moisture in the distributor, ignition module, spark plugs, or high-voltage wires. 2. Spark plug issues: Damaged spark plugs. 3. Insufficient voltage: Low battery voltage. 4. Switch disconnection: Inertia switch is turned off. 5. Check intake manifold and timing chain: If the car starts normally when warm but has this issue when cold or after sitting for a while, inspect the fuel system. For pre-2010 models, it's recommended to check the intake manifold and timing chain. 6. Prevention and solutions: Avoid direct engine washing. Regularly inspect, adjust, or replace spark plugs. Have damaged components checked and replaced at authorized service stations. Charge the battery. Reset the inertia switch to restore the circuit.
