Hi,
I recently change the belts on my 2.5 TDi AKN engine, and when running the dynamic timing check noticed that the coolant tenp would not rise above 80 deg C , as measured by Vagcom.
The oil temp reached about 93 degrees, and the dash temp gauge settled at 90 degrees as normal.
I assumed that the temp sender was faulty, and replaced it. However, on rechecking with Vagcom, the situation is unchanged - oil temp in the low 90s, but coolant temp around 80 degrees.
I am assuming the reported coolant temp is wrong, as the oil temp and dash gauge seem correct.

Any ideas ? Can the coolant temp output/value be modified in Vagcom ?
