Hey all, I have a 2.0T FSI and was wondering if anyone had any idea what the temperature reading in these measuring blocks in 01 Engine are?

247 (1st slot) and 252 (4th slot)

They're unnamed and I can't find any information online, I am wanting to know because I have a starting issue where I need to leave my ignition on for 5 minutes first if I want it to start. These measuring blocks start at a temp reading of around -9*C and slowly rises up to around 40*C over 5 minutes then the car starts perfectly fine.

If I can find out what this reading is coming from, that would be extremely helpful in diagnosing/ruling out...

Thanks!
