First, remove the engine cover by pulling it up at each corner. Next, disconnect the wiring harness by pressing the retainer tabs toward the firewall until you hear a click. The whole wiring harness will pull back as a unit when all of the connectors are released. Then, firmly grab the coil pack and pull upwards until it slides out.

Are there any problems with the Volkswagen Golf coil pack?
Bad Coil Packs are one of the more problematic ignition issues that can occur with the Volkswagen Golf. A bad oil pack can make your Golf almost un-drivable. Or it may have little effect at all on the engine’s ability to run.
How do I find the resistance of my VW coil pack?
This particular specification is always indicated on your vehicle’s manufacturer manual script, or you can obtain the resistance value through your multimeter and observe the reading value displayed on its screen. Make sure you locate the VW coil pack in your car.
How does a VW coil pack ignition system work?
When the burning process commences, the VW coil pack creates up the power between 50,000-75,000 volts. Subsequently, the ignition control usually receives its signal from the electronic control module resulting in voltage discharge to your spark plug from the VW coil pack through the cable of the spark plug.
Where is cylinder one on a VW Golf?
An important thing to understand when finding the location of cylinder one is that it’s going to be the first cylinder in the firing order of the vehicle, and not the first cylinder that you might see when looking at the engine. The P0302 trouble code will trigger the Golf’s service engine soon light.
How do you know whether your VW coil pack has a problem or not?
In case your coil pack is in bad shape, it is prone to causing misfiring. This is more evident when you experience loss of sparks or fire in your cylinders. Below are several symptoms of a damaged VW coil pack; it includes:
How does a VW coil pack work?
So, how does a VW coil pack work? Well, the spark plug generates parks enhancing the fire to start from a maximum voltage supply. When the burning process commences, the VW coil pack creates up the power between 50,000-75,000 volts.
How many volts does a VW coil pack have?
In your car, the VW coil pack converts 12 volts of energy from your battery into a thousand volts required to intensify the cars’ spark plug. It acts as an induction; hence it is appropriate you place a maximum voltage transformer.
How to connect a VW coil pack to a multimeter?
Locate the negative as well as the positive terminal of your VW coil pack and connect on both the negative and the positive leads of your multimeter. You might be lucky and find that the negative and positive terminals are placed in symbols on your coil pack but others do not come with the markings but instead have the two pins found on your connector.
What is the resistance of a VW coil?
The primary coil resistance should range between 0.4-2 ohms, but make sure you refer to your manufacturers’ manual script to confirm this. However, if the reading displayed on your multimeter screen is zero, then consider your VW coil pack electrocuted internally, and the same for the primary windings, meaning you need to replaced them.
What does it mean when VW coils are zero?
If the reading displayed is zero, it also means your VW coil pack is electrocuted and needs to be replaced to function correctly. In case the reading value is exceeded, then it means your coil pack is open, and it also requires a replacement.
What equipment is needed for a VW coil pack?
Equipment needed for conduction of VW coil pack includes: A digital multimeter. Essential hand tools for removal of the VW coil pack. Below are several steps that will guide you on how to run a test on your VW coil using a multimeter.
What is a coil pack?
DIS, or wasted spark systems, use what is commonly referred to as a “coil pack” to send voltage to each spark plug wire, where other vehicles use a single coil for each spark plug wire.
How to tell if ignition coil is bad?
These are the symptoms of a bad ignition coil: Misfires – Check Engine Light: Misfiring is usually the first and most common symptom, and in most vehicles today, this will appear as a Check Engine Light. The misfire will either be on a particular cylinder, or random.
What is an inline ignition tester?
An inline ignition tester like OEM 25227 can be helpful. This unit runs inline with many spark plug wires and/or coils and gives you a window to see active spark.
How many volts does an ignition coil take?
Types of Ignition Coils. Ignition coils come in various types of ignition systems, but all of them take energy from the battery (usually 12 volts) and convert it to a high enough voltage (50,000 volts or more) to create a spark.
Why does my ignition coil fail?
Ignition coils fail in 2 ways – either complete failure and lack of output, or intermittently, meaning, the coil gets weak, output gets low, or the coil sometimes works and sometimes doesn’t. Because of this, intermittent problems are more difficult to diagnose.
What does it mean when your car idles rough?
Rough Idling or Hesitation Under Load: As stated before, most ignition problems that are misfires also cause a rough or bad idle, but in cases where a vehicle (mostly older vehicles) does not have a Check Engine light or ability to detect a misfire, a rough idle or constant stalling of the vehicle may indicate a bad ignition coil, or a coil that is over-heating, whereas hesitation under load could also be a sign of a weak coil.
What happens if you have a bad ignition coil?
A weak or damaged ignition coil can cause engine misfires, stalling, poor performance, and lower fuel economy. A completely faulty ignition coil can often keep the vehicle, especially a 4 cylinder vehicle, ...
What is the code for a misfire on a Volkswagen Golf?
Volkswagen Golf P0302: Misfire Detected – Cylinder 2. November 28, 2018 by Jason. P0302 is a relatively common Volkswagen Golf trouble code. It stands for: P0302 is certainly a cause for concern, and can be a threat to the drivability the Volkswagen Golf.
What is the trouble code for a golf?
The P0302 trouble code will trigger the Golf’s service engine soon light.
Why is my spark plug P0302?
Bad Spark Plugs – Spark plugs are one of the most common causes of P0302. Take a look at the electrodes and see if they are in good shape. Most vehicles now come with iridium plugs that need changed very infrequently. That being said, the plugs are a great place to start. Here’s a great video on how to see if a spark plug is bad.
What causes P0302 on Volkswagen Golf?
Here are the most common problems that will throw the code. They are presented somewhat in order from most to least likely to be causing the code: Bad Spark Plugs – Spark plugs are one of the most common causes of P0302.
What happens if a fuel injector goes bad?
Bad Fuel Injector – If you have a fuel injector that has gone bad, it won’t be able to properly atomize the fuel and you’ll get the P0302. Here’s a good video on how to diagnose an injector, but it can be a little tricky. This is definitely not the place to start.
What happens if the cam sensor doesn't work?
If the ECU is not getting the right signal from these sensors, the vehicles timing is not going to sync up and it’ll misfire .
What does P0301 mean on a car?
It will often be accompanied by codes P0301 -P0308. These particular codes indicate that there is a misfire in one of the other cylinders as well.
What Tools Do I Need To Test The Ignition Control Module And The COP Coils
As I mentioned at the beginning of this tutorial, you don't need a scan tool. Here are the tools you'll need:
Ignition Module Circuit Descriptions
The ignition control module has two connectors. Looking down at the ignition module (with the ignition module still bolted in place), you'll notice that the ignition control module has a left connector and a right connector.
COP Ignition Coil Circuit Descriptions
OK, before we jump into the testing part (in the next page), you need to know a few more things and this is what each of the three wires that connect to the ignition coil connector do.
