VAG Com Channel 7

What is the significance of seeing the temperatures in group 7?
I can't find anything in the forum.
Group 7, channel 2, is showing a temperature of over 100°C for me. What could be the cause? That's probably not coolant.
The oil temperature at that time was approximately 75°C, so it can't be.
Diesel temperature perhaps? But that high after such a relatively short driving time?

Best regards,
Johannes.

engine codes?
Year of construction?
vehicle?

A little more input, please... our crystal ball has ended up in the glass container.

I thought it would be the same for all chests.

Again, AFB.

Sorry again.

I will try to improve myself.
