How do you know if power is getting to the coil?
Locate the positive or power wire attached to the engine coil.
- If this wire has no power, then your ignition coil is not receiving current.
- If this wire has power, then the wiring from the ignition switch to the coil is working properly and you can move on.
Why does the same ignition coil keeps failing?
The leading cause of premature failure of an ignition coil is due to a worn or bad spark plug ignition cable. A bad spark plug ignition cable will have a much higher than normal resistance. This high resistance causes a very high amount of voltage to be generated from your ignition coil’s secondary winding.
How can you tell if a coil wire is bad?
If your car is experiencing any of the problems listed below, you may have a faulty ignition coil on your hands:
- Engine misfires.
- Rough idle.
- A decrease in car power, especially in acceleration.
- Poor fuel economy.
- Difficulty starting the engine.
- Check engine light is on.
- Exhaust backfiring.
- Increased hydrocarbon emissions.
Do ignition coil wires go bad?
Ignition coils tend to fail because of bad spark plugs or plug wires. If your vehicle’s fuel-to-oxygen mixture is either rich or lean, therefore, your ignition coils may fail prematurely. Additionally, engine heat and vibrations can cause damage to ignition coils.
How do I stop my coil from burning?
The best ways to stop your coil from burning are:
- Prime your coils.
- Stop chain vaping.
- Reduce power settings.
- Keep your vape tank topped up.
- Use a vape juice with more PG.
- Try a vape juice with less sweetener.
- Use temperature control.

What controls an ignition coil?
Some ignition coils contain a solid state driver module which is part of the ignition coil and is controlled by the Powertrain Control Module (PCM). Others have the primary winding wired to and directly controlled by the Powertrain Control Module.
How do you test a VW ignition coil?
Use an Ohmmeter to test the coil. Place the red or black lead from the meter to the center of the coil (secondary post), and to either one of the terminals, 1 or 15 on the coil. A reading of 9,500 – 10,000 Ohms, sometimes less, indicates a good coil.
Are there any problems with the ignition coil on a VW?
And for years, Volkswagen vehicles have had issues with ignition coil and connectors that fail, potentially leaving drivers stranded with a stalled out engine and no power steering or brakes. Honestly, it isn’t hard to tell when an ignition coil is having problems. Let’s just say when they fail, they don’t do so in a subtle way.
Where are the coils in a VW engine located?
According to some mechanics, the coils in VW engines are placed at the top of the engine and covered in a way that when the hot air from the engine rises it gets trapped. Almost creating an oven for the coils to bake in.
What happens if the wiring harness fails on a Volkswagen?
A wiring harness failure can have a huge impact on the entire car, as many of the Volkswagen’s functions are now automated, especially in the recent models.
