I’m a big fan of maintaining my vehicles. I firmly believe that a well maintained vehicle will last you a good long time and give you years and hundreds of thousands of miles. Right now my VW Jetta has 150k+ on it and is going strong. I believe this is due to the maintenance schedule that I keep with it. You can check my recommended maintenance schedule here, some things I no longer do but for the most part that is the schedule that I follow. Really, the only thing I don’t do on that post anymore is the brakes, I found that I was not really using them up at all and it was a waste of time and money. I just wait for them to wear out now.
This is the 30k maintenance on a 2010 VW Jetta Wolfsburg. It involves replacing the spark plugs and coil packs. It’s the 2.0T motor and I have found that for reliability sakes, I replace the coils every 30k as well. I have not done this on other vehicles that I own, but this one seems to like it. I just tell everyone that she’s high maintenance! I use the R8 Audi Coil Packs when replacing them as well as OE replacement spark plugs.
The first thing you need to do is to pull off the plastic engine cover. This is easily done by just pulling up on it; the cover should release and be easily removed. It is held on by small plastic “balls” that keep it in place.
The next step is to disconnect the electrical connectors on the coils. To do this, you press down on the little clip that is holding it in place and pull it back. They may be a little finicky but should release and slide off. Go down the line in order so that you can slide the entire electrical assembly back once they have all been released.
Press the tab and release the connector
All Connectors Disconnected
Once all the electrical connectors have been released, and you have slid the electrical assembly back off the coil packs, you can pull the coil packs off the spark plugs. If yours are like mine, they will be quite difficult to pull straight up. I usually twist them a little to loosen them and then they will come off. This is not very hard, just takes a little patience. They should “pop” when you remove them.
I replaced the spark plugs with Bosch Double Platinum’s. Using a 5/8th spark plug socket and an extension I put the socket down the spark plug hole and removed the spark plug. I do this one at a time and in order as to not get confused about which one has been done. Once all the plugs have been replaced, you can put the new coil packs on and reconnect the coil pack electrical connectors. When you slide the connectors back on the coil packs you will hear the clip “click” into place.
That is all I do at the 30k mile marker. There is one other maintenance items that get done when I do this, but I do them at the 15k mark as well so it’s more of a 15k maintenance item. The item that coincides with this is the cleaning of the air filter. I have a K&N filter on my car so I clean it, if I did not have one I would replace it.
