Weird, @fEArmW and @hippithe. Mine look just fine (I have 109K miles on the car).

Thanks go to @a44mark for the writeup. Worked like a charm for me this weekend.

This torx mount for the coil pack rail on the passenger side nearest the front of the engine was a bear. Need a low-profile ratchet/torx drive to get to it since the airbox is in the way. @kevrhoff, I was not able to understand your pic since it's from a different car.

How to remove sensor from bottom of Coolant reservoir?
 

I didn't remove the sensor, just the electrical connection. There a picture of the reservoir bottom side in my thread.

How do you disconnect the electrical sensor from the bottom?
 

I can't figure out how to remove the electrical connection from the bottom of the tank. Don't want to push too hard and break it. Is there a latch or something?

Lol, there is a trick, google "vw auto electrical plug"...

YES!!!! You are the man. That thing was driving me nuts!

Thanks for the write up
 

Just did my own 55k service. The write up for the plugs was very helpful. Used two tie bands, one on either side of the coil pack, to pull them. Worked great!

Regarding the coolant bottle, it seemed easier to me to just unscrew the mounting bracket than mess with the sensor. Two torx screws. And a little bungee to hold the bottle out of the way. Plenty of room to get at the harness.

All in all, a pretty easy job thanks to the great write up. Thanks!

Hi, bit late to thread here, but, can anyone guide me where to purchase a couple of the torx ignition rail mount screws as shown in the above pic? I even tried the dealer who couldn't locate it on the parts breakdown schematic. Thanks.

I would just try to use a regular screwdriver that will fit snugly on the torx screw. They aren't very tight. I didn't have the exact torx driver, but was able to use a different size to get the job done.

Take one off from other rail and bring it to Lowe's or Home Depot. You can match up a metric screw there. Doesn't have to be Torx head.
