2010 Volkswagen Jetta Wolfsburg Tune-Up

2.0 TSI Engine CoverI had to do a tune up on my Volkswagen Jetta Wolfsburg Edition this weekend and it was pretty easy to do.  On these cars, a tune up consists of changing the plugs and the air filter, there is no fuel filter that is serviceable and the PCV system does not have a valve.   I have an aftermarket intake on my car, so I just cleaned the Air Filter with the cleaning kit that I have.

If you happen to have and aftermarket intake, the procedure to clean the air filter is as follows; First you will need to remove it by loosening the clamps.  Once you have unscrewed the clamps and removed the filter from the car, you will spray the filter with the cleaning solution and let it sit for 10 minutes.  When the 10 minutes is up, use water to wash off all the dirt and solution away from the filter, I use my garden hose and hit it pretty hard with water; this visibly removes the dirt that has been building up on the filter.  Let the filter dry.  Once it is dry, you can use the cleaning kits supplied oil to oil the filter.  Make sure that you cover the filter in oil and re-install it.

To change the plugs, you will need to remove the plastic engine cover.  You can just pull up on the edges of the cover to “pop” off the plastic piece that is covering the head.  This will then expose the coils.  You will need to disconnect the electronics that are connected to the coils.  To do this, push on the plastic clip and pull the connector back away from the coil.  I found that I needed to disconnect all four connections before I could get the connectors all the way off the coils.

Once the connectors are removed, you can pull the coils straight out of the spark plug well.  This may be a little difficult but be patient and keep trying.  You may need to twist the coil a little bit but they will pull off.  When you finally get them off the spark plugs, you can use your 5/8 spark plug socket and an extension to remove the spark plugs.  I do this one at a time so as to not get confused.

I replaced the NGK spark plugs that I was using with Autolite Iridium Spark Plugs.  I have used them in the past and they have worked well.  I gapped them at .040 and the car seems to be running perfect.  Installation of the plugs is the reverse of the removal.  The only caveat is that you only tighten the plugs ¼ turn past hand tight.  I believe that the proper torque spec on the plugs is 18 ft/lbs if you want to be perfect, but the standard ¼ turn past hand tight worked fine for me.

When all of the plugs have been replaced and the coils are on, make sure that all the coils are secure and pushed all the way down onto the spark plugs.  Now, reconnect all the electrical connections to the coils and replace the plastic engine cover.  That’s it, simple tune-up on a 2010 Volkswagen Jetta.
