Where to Fix Your Mercedes’ Ignition Coil in Plano
by europewpadmin July 23, 2024The ignition coil in your Mercedes Benz is part of the ignition system of the vehicle. It is mainly tasked with the function of stepping up the voltage from the car battery to generate a spark in the spark plugs. This spark initiates the fuel-air mixture in the engine cylinders to burn and start your car. A faulty ignition coil can cause several issues on the engine such as misfires, poor performance, and even damage.
What Causes the Ignition Coil to Fail?
- Wear and Tear: Ignition coils are prone to wear and tear because they deal with high voltage and are always under stress in the engine compartment. These factors cause the internal parts of the coil to degrade over time and therefore fail.
- Heat and Vibration: The engine bay is a harsh environment to live in with constant vibrations and high temperatures as the mechanical parts are running. These conditions can make the internal components of the ignition coil wear out, which leads to the coil not working.
- Moisture and Oil Contamination: When moisture or oil finds its way into the ignition coil, the circuit may be shorted. This is because the liquid affects the electrical conductivity within the coil and this causes it to malfunction and fail.
How To Fix the Ignition Coil In Your Mercedes
Begin by unscrewing or taking off anything that may be covering or could be in the way of accessing the ignition coils. Gently pull the electrical connector off the faulty ignition coil to ensure that it is not damaged in the process of repairing the coil. You can then use your socket set to remove the bolts holding the coil and then pull on the coil to remove it.
Now take the new ignition coil and fit it in the same position as the previous one. Fasten it with the bolts and re-connect the electrical connector. After the new ignition coil has been fitted, replace any cover or part that was removed earlier. Switch on your Mercedes and let the engine run for some time. If all seems well, then drive your car around for a few minutes to ensure the problem has been solved.
When to Seek Professional Help
The replacement of an ignition coil in Mercedes is not a simple DIY. If you do not have experience in handling this issue, it is advisable to seek the services of an expert mechanic. They can diagnose the problem more accurately and treat any fault that may be causing the problem in the first place.
How to Avoid Future Ignition Coil Problems
- Regular Maintenance: It is always wise to seek the services of a professional on a regular basis so as to be in a position to spot any problems that might be developing into big issues. The normal checks and services enable one to confirm that all the parts such as the ignition coils are in the right condition.
- Use Quality Parts: When it is time to replace parts, make sure to use the best quality parts you can afford. These are original auto parts that are developed to fit your vehicle and are usually more reliable than the cheaper versions. Purchasing good quality parts can go a long way in helping you avoid frequent replacements thereby cutting on the expenses.
- Keep the Engine Clean: The next thing that should be done is to look at the engine bay for signs of oil or moisture leakage. Leaks can lead to contamination which in turn harms the ignition coils.
