At a speed above 120 km/h, the check engine light comes on and the horse power of the car decreases. During diagnostics, it appears that the turbo does not work, it puts itself into protection mode. This happens with the P0299 error code. Sensing low air pressure in the turbo. Some masters advise me to change the turbo altogether, some tell me to repair the turbo, and some tell me to change the turbo manifold. Considering that Chevrolet parts are expensive in our country, I want to solve this problem with accurate diagnostics at a low budget. The car has been used in Azerbaijan for 4 years
