To the original topic, I did my 40K today. A few things may be useful to folks:
1. Oil change was done by draining from pan. Got a few extra milliliters from canister with my mityvac. Remove the plastic wire harness holder (1 screw) and rigid line in front (2 screws) first. Push back and down on the black wire harness to the right rear of housing. Lid and filter come up and right at an angle to remove. Cover white insulation with plastic bag before removing. For reinstalling, I used 22 ftlbs for new oil pan bolt, 18 ftlbs for filter housing lid. 4.5L LiquiMoly 4200 5W30. Put the new filter on the lid all the way to top before trying to reinsert it. Remove the plastic wire harness holder (1 screw) and rigid line in front (2 screws) first. Push back and down on the black wire harness to the right rear of housing.
2. Fuel filter was done without VCDS. I emptied canister with my mityvac, cleaned out the sediment with paper towels, and filled 2/3 of the way with stanadyne and LMDP. Sank new filter in and held my finger over center hole while filling it the rest of the way by pouring onto top on filter. The LMDP just flows down outside the filter through slots in the side of the top. It's apparent when you see it. Once it stopped flowing off the top, I removed my finger from the hole and added enough LMDP to the top until the level inside the center hole was very close to top. Buttoned it up and started the car. No difference in cranking. Started right up immediately, ran smooth as butter. No fiddling with key on or VCDS.
3. DEF. bought a 1/2 gallon filling jug from IDParts and a 2.5 gal box locally. After screwing the can onto the DEF tank in trunk, I emptied in by pushing down, then I cut a hole in the bottom (leave one side connected so it holds spout from box in hole) large enough for the 2.5 gal box spout and just kept filling and emptying until I ran out. (3 gal total, need to get more). Didn't spill a drop. The special little 1/2 gal jug made it simple and its reusable as an auto-off DEF measuring funnel
4. Reset oil change by turning on ignition while holding 0/0 Set button on cluster. Reset service reminder by doing the same with hazards on.
Forgot to get a cabin air filter.
