We dropped the oilpan of my 2000 TT more or less out of curiosity and perhaps just in case. I had no idea if these engines were of sludge building type so a little work for peace of mind.
Previous owner has fed Mobil 1 ESP 5W30 and I have used Mobil 1 0w40.
No sludge, just a little of material in upper right corner (on photo) which came off easily. Oil pickup tube was open and clean and bottom end seemed very clean.
Filled with last Shell Helix Ultra 5W40 I had in stock. Next change will be with Mobil 1 0W40 again.
