Hello friends, I bought 2 months ago a Chevrolet Astra Turbo Diesel 2001 and makes me a extrana fault. When I go to route and circle at a speed of 130 or 140 km. The car is now if I reduce the speed at 80 km. For a few minutes, or to load fuel, the motor cooling indicator light turns on the board, the car is put in safe mode, stop walking the account and loses strength the engine. The radiator temperature does not exceed 90 degrees. I wait about 15 minutes with the engine stopped, the whole problem was destroyed, and I can continue the trip.
Now in city with short stages it does not, only en route when I make 50 km trips. Or more
take it several times to review, they do not know how to say why they fail, they make the computerized diagnosis, they reset it, they changed a couple of sensors and modules, but it does again. Thank you very much for your time. Kind regards
