Hello everyone in the group! I want to ask you about a problem. The car is a seat altea xl 2007 diesel. The problem is the following: During normal driving, the car runs well, however... in warm weather and when I drive a long distance with frequent stops, after about 3-4 hours of driving, the car starts to lose power, cannot increase revs, shakes. After resting for a while - 15, 20 minutes, the problem is fixed, when I drive like that again, it starts again. And the antifreeze needle shows 90 degrees, it does not reach 100 and more. It only happens during long driving and load in warm weather, the rest of the time it is fine. Nozzles, turbo and other components work within limits, normally. The water pump and antifreeze were replaced less than 10,000 km ago. Please advise what could be the cause?
