- Found code P0299 for turbo underboost condition. Checked desired boost pressure is way above actual boost pressure. Remove turbo bypass valve and found diaphragm in turbo bypass valve to be broken. Recommend remove and replace bypass turbo valve and road test. Desired turbo pressure and actual boost pressure are now matching when driving.
