What is the reason for the misfire and shaking of the Volkswagen Phaeton W12?

[McAngelina]

Volkswagen Phaeton W12 misfire and shaking is caused by: ignition system failure. Here are the details: Cause Analysis: Ignition system failure, spark plugs and ignition coils should be checked. Spark plugs are an important component of the car engine ignition system and are also a wearable part that needs to be replaced regularly. If spark plugs are used for a long time without replacement, the electrode gap will increase, which will affect their ignition energy. If spark plugs are used for a long time without replacement, carbon deposits will also appear on the electrodes, which will also affect the ignition energy of the spark plugs. Solution: For ignition system failure, first start the engine and check if the warning light is on. If it is on, a fault decoder should be used to read the fault code, and the low-voltage circuit fault should be diagnosed based on the content of the fault code; if the warning light is normal, the high-voltage circuit of the ignition system should be checked.
