because my spare part finally arrived last night I could attempt fixing my car again this morning and it took....

12 minutes in total, slight an improvement to the last time, when it took 5+ hours.

What did I do different?

• I knew where the part was located, 4 hours saved
• I cut the old sensor in the middle instead of fideling with it for an hour, 59 minutes saved
• I did not remove the coolant reservoir this time, 10 minutes saved

now the bill in total come out to:

• wrong part 80$ - thanks ECS for providing this, you send me the part for a 1.8T...
  
• comfirming diagnostic 90$
• right part 40$
• so 230$ total

compared to the quoted 360$ of the shop
