Alltrack operating temp

[Mc_Gusto]

Well I don’t think it’s an airlock issue. Can’t be 100% sure but ive left the cap off overnight and it doesn’t seem to have cured it.
Seems to occur mostly on cold days and only on the first time I start the car. Ie. if I run the car later in the day or switch the ignition off / on it seems to recalibrate to the standard 90 degrees Celsius

Weird and annoying but not a major issue really..when it’s due for a service I’ll see what the mechanic has to say I guess

Same issue in my car as well. When car does dpf regeneration temperature drops to 75-80c but after regeneration process comes back to 90c.
So far, no vw tech could explain me about this... Let be honest, i do not mind.
