Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace an ignition coil on this 2004 Volkswagen Jetta with 1.8L engine. The items you'll need for this include a new ignition coil from 1AAuto.com, a Phillips screwdriver, and a flat blade screwdriver. For ignition coils 3 and 4, you'll need a 10mm socket and ratchet. For ignition coil 4, you'll also need a 5mm Allen bit.
First, we have to remove the engine cover by loosening these four Phillips clips. Just loosen it while pulling up on the engine cover, and then the engine cover pulls off and you can set it aside. For ignition coils 1 and 2, all you need is a flat blade screwdriver. Just press on the tab and pull the harness free, and then just pry the ignition coil up and out. Then, you just take your new ignition coil, push it down into place, and reconnect the harness.
To access ignition coil 3, you're going to have to remove the small air box. Just using a 10mm socket and ratchet, remove this 10mm nut and set the air box aside. To get to 4, you're also going to have to remove these three 5mm Allen bolts. We'll just fast-forward as Don removes those. Pull the bracket off and set it aside. Then just like before, push on the tab and pull the harness free. You may need to pry it to separate it, and then just pry the ignition coil up and out.
On the right is an old ignition coil; on the left is the new one from 1A Auto. You can see that they're identical, and they'll fit exactly the same. Take your new ignition coil, push it down into place, and then reconnect your harness. Replace the bracket and the three 5mm Allen bolts that hold it into place. We'll fast-forward as Don tightens those up. Now, replace that small air box, the 10mm nut that holds it into place, and just tighten that up. Line up the four Phillips clips with these four holes. Just push the engine cover down into place and tighten up those four clips. You're all set.
