A few days ago I noticed that my fat guy doesn't go to 90 degrees after 15-20 minutes, but after the first meters. The reading is a little over 90 degrees. Even if he's out for a whole office day, he's almost immediately back to a little over 90 degrees in the evening after starting.
The heating is normal. Coolant is also enough. In the traffic jam on the highway, however, it buzzes quite loud and occasionally white cloud comes out in the back.
Does anyone have a tip for me?
Can you use a diagnostic device to check if there's something wrong?
