I am troubleshooting thermostat issues/radiator fans kicking in too early.
It was suggested to monitor G62 (coolant temp on the engine outlet) and G83 (return from the radiator). Apparently these two are responsible for activating the radiator fans.
How can I see data for those? How to find them?

matthew is probably the best bet on this forum. Or you could ask the same on VWVORTEX as they have a few more active users for your motor. However in General I would look at Live Data on Control Unit 01 and scroll through the channels and see if anybody has left any good descriptions to help you find the correct channel.

Thanks for your response.
I tried on vortex and actually that is where I came from.
I also looked in all gauges, charts, live data, and any option I had on my app to find any useful information.
There are plenty of "channels", but without description. Yet they contain some parameters.
I went through over 100 of them and the only one I found was the engine temp, which is not exactly what I need.

I will check 130. If that is the right one, I will be so pissed. I stopped at Channel 115...  |

OK, so I confirm.
Channel 130 contains G62, G83 (called as engine outlet and radiator outlet, respectively), thermostat % opening (not sure how it is calculated), and cooling efficiency (or something like that).

Good news, I will try and update the descriptions later today. |

matthew is probably the best bet on this forum. You tagged the wrong Matthew, so I'm just seeing this message. I see where the OP seems to have gotten through with collecting the required information. |

thermostat % opening (not sure how it is calculated), and cooling efficiency (or something like that).
Good news, I will try and update the descriptions later today. The cooling system is designed to stop allowing the coolant to heat up above the 87*C. At operating temperature, the 90*C you see on your temperature gauge in the dashboard is actually 87*C (for the purpose of not triggering anyone's OCD and leaving the needle in the middle of the gauge). The fans are set to cycle much earlier so as not the overshoot the actual 87*C. One can drive the car hard and exceed the 87*C, but once the harsh driving session is over the coolant temperature should go back to the 87*C after a few minutes of idling. If it doesn't go back to this value, there is an issue with the cooling system such as a partially block radiator, incorrect coolant, or fans not cycling properly. Note: MK5 and MK6 Golf / Jetta in the 2.0L category are plagued with fan switch issues, so that also needs to be checked out. |
