Working on the plugs now on my car. Unfortunately in step 7 the tiny plastic tube on the bottom of the sensor broke off. Off to VW on Monday to see about getting a new part.
So far the most difficult part of the operation has been step 7 and removing the electrical connectors to the various sensors. Still not sure what the trick is. Presumably one inserts a very small screw driver somewhere and that releases the lock which then allows the electrical plug to pull out. Or maybe there is a special tool for this?

Well I may replace that sensor or maybe not.
The small plastic tube which comes out of the side and fits into a rubber hose broke off in the hose. So I bought some small brass tubing of similar inside diameter, enlarged the hole in the sensor where the plastic tube broke off and using JB weld I replaced the plastic tube with a small section of brass tubing. Now I need to get the clamp off of the rubber hose (cut it with a Dremel tool?) and get the broken plastic tube out. Then after I finish changing the spark plugs I'll try to install the repaired sensor. If it doesn't work I'll buy a new one.

The wiring harnesses just need patience. Some of them have clips that need to be pushed in / pushed back. You have to figure your way around them. Just be careful and don't try to yank them too hard. A heat gun with lower power could help for stubborn harnesses.
The sensor up front was a little tricky to get off. I used a panel popper and fiddled around with it until it popped out. I don't remember removing the hose attached to the sensor.

I didn't want to remove the hose either. When the sensor finally popped off, which took a lot of force, it broke the little plastic tube on the bottom that went into the hose. I've repaired the sensor and hope it still works. But to reinstall it I have to get the clamp off the hose and then remove the little piece of broken off plastic tube stuck in it. Then re-clamp the sensor tube into the hose.
If I had to do it again I would first grind down the little **** on the metal bracket that were preventing the sensor from sliding off. Then little force would be needed to remove it.

...thank you for excellent plug write up...will be doing mine in year or so...I'm probably going to use the new set I have that a Bentley dealer took out without my ok at 18,000 miles...JimB

Amazing job amigo. My mechanic quoted me at $700 to change my spark plugs which I consider pretty reasonable.

Finally did mine with new coils too. Some of my cable conduct was cracking so had to patch up with insulating tape.
Took me 5hrs but I was going real slow and that included a run to the shop for more supplies.
I used Bremi #20112 coils and OEM NGK R PZFR6Q-11 spark plugs.
Thanks to John V for the DIY.

Why only 11 of 12 spark plugs on a W12?
