Why does the middle gauge rotate when the Passat fails to start?

[McArya]

The reasons and solutions for the middle gauge rotating when the Passat fails to start are as follows: Battery depletion: If this occurs, please call the service station for assistance, jump-start the car, or temporarily start it, but you must take it to the service station to recharge the battery afterward. Fuel flow obstruction: Place the car in a warm environment, and it should start after a while; alternatively, thoroughly clean the fuel system to resolve the issue. Poor ignition system performance: Remove the spark plugs, clean the oil between the electrodes, and reinstall them to start the car. A more thorough solution is to inspect the ignition system and address the causes of low ignition energy, such as spark plug electrode gap, ignition coil energy, and the condition of the high-voltage wires.
