Ignition Coil A0001502780 For Mercedes W203 W204 X204-GLK W164 X164-GL W209 W211 W212 W221 W251-R W463-G VITO639  SPRINTER906

When the automobile ignition coil fails, the following problems may be caused:

1. Engine starting difficulty: The ignition coil is responsible for generating high voltage to ignite the mixed gas. If the ignition coil fails, it may lead to insufficient ignition ability, making the engine starting difficult or impossible.

2. Engine jitter or misfire: The failure of ignition coil may lead to unstable ignition ability, which may lead to jitter or misfire when the engine is running. This will cause the engine to run unsteadily, reduce power and even cause the engine to stall.

3. Decline in fuel economy: Failure of the ignition coil may lead to insufficient ignition capacity, which makes the fuel unable to burn completely, thus leading to a decline in fuel economy. The fuel consumption of vehicles may increase and the mileage may decrease.

4. Increased emissions: Failure of ignition coil may lead to incomplete combustion of fuel, resulting in more exhaust gas and pollutant emissions. This will lead to excessive vehicle exhaust emissions and have a negative impact on the environment.

For the inspection and maintenance of automobile ignition coil, the following steps can be taken:

1. Check the ignition coil connection: Check whether the ignition coil connection is firm, not loose or corroded. Ensuring a good connection can solve some ignition problems.

2. Check the wires and coils: Check whether the primary coil and secondary coil of the ignition coil are damaged or short-circuited. Use a multimeter to detect the resistance value to ensure that the coil is normal.

3. Check the output of the ignition coil: use the ignition coil tester or oscilloscope and other tools to check whether the output voltage of the ignition coil meets the specifications. If the output voltage is unstable or too low, it may be necessary to replace the ignition coil.

4. Replace the ignition coil: If it is confirmed through inspection that the ignition coil is faulty, a new ignition coil needs to be replaced. Select the ignition coil suitable for the vehicle model and engine, and ensure that it is installed correctly.

It should be noted that if you don't have relevant technical knowledge and experience, it is recommended to hand over the inspection and maintenance work to a professional automobile maintenance technician or service center. They can accurately diagnose problems and carry out maintenance through professional equipment and experience to ensure the normal operation of the car.
