Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we'll show you how to replace ignition coils on this. This subject vehicle is a 2003 VW Passat. It has the 1.8 Turbocharged or 1.8T motor which is the same for a lot of different VWs as well as Audis. The only tool you'll need is a large flat blade screwdriver on this vehicle. It may be a little different for the Audi if the engine vanity cover is different.
You want to remove this cover here. There are three little clips. Use a large screwdriver, turn 90 degrees, let them pop up, and 90 degrees, here. I'm going to tap it a little bit, 90 degrees. They pop up and then this cover rights up and off. Each coil has a little plug on. You just push on that tab and then pull the harness off. Obviously, if you're doing all four you do that for each one and then just kind of move the coil a little bit. Pull it right off and out.
The new coil from 1A Auto is just like the original. You go down in nice and straight and just press it right down in and reconnect it. It's a direct fit and then repeat for the rest of them.
Just place your cover back on. You could just use your oil filter or your oil filler as a centering point. Now use a screwdriver to press those down. Turn to 90 degrees.

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.

Delivered quickly, and fixed my P0300/P0304 check engine code. No more misfires in cold weather is always a good thing, and 1A's price on a set is beyond inexpensive.
Perfect Fit

They fit just perfect, same quality as the original. Car runs perfect better than before. It's an older VW that will be around a little longer. I will purchase parts again in the near future. Better than Auto Zone, O'Reilys, Napa. Better prices.

These coils that you have asked me to write a review for I honestly must say that I am displeased with. Reasons being two of the coils were bad . I had a mechanic to look at my car and after looking at a couple of things and finding nothing decided to look and test the coils and found that two of the four was bad. So I had to replace them meaning extra money spent that I really shouldn't had too. I put my trust in a company that failed me. If I knew how to return these items I surely would in hopes that the company would refund me for the coils thats in questioing at least if nothing more. Sincerely, Davida G.

I purchased this set in Apr 2021. Within 2 months, the first coil failed. Two months later the next coil failed. To date, all 4 have failed within 10 months. Do not order these!
