Thank you sir, you saved me money. For anyone doing this and wondering about the freefloating hose at the bottom of the coolant reservoir (part# 8D0121428), that doesn't plug in to anything so dont worry.
Just removed my reservoir and saw that and freaked out because I couldn't find where it goes and it looked like it was attached to some electric where it meets the reservoir. Thank you for pointing this out! So much stress removed!
Justin help out, I got B2S1 no activity fault, on VCDS it either is stuck Midway on the lambda reading, but sometimes it's doing what it should be with doing up and down voltage. The lambda is new.. what else am I chasing wiring issue to the probe?
