The owner reported a noticeable loss of power during highway driving and a faint whining noise from the engine bay. After scanning the vehicle with a Hyundai/Kia-specific OBD2 tool, I found multiple fault codes: P0171 (System Too Lean, P0016 (Camshaft Position Actuator Circuit Range/Performance, and P0299 (Turbocharger Boost Pressure Too Low. These codes pointed to a failing turbocharger and potential internal engine wear. I performed a compression test and found that two cylinders had significantly lower compression (120 psi) compared to the others (155 psi. A leak-down test confirmed that the intake valves were not sealing properlylikely due to carbon buildup and worn valve guides. <dl> <dt style="font-weight:bold;"> <strong> Compression Test </strong> </dt> <dd> A diagnostic procedure that measures the pressure inside each cylinder to assess engine health.
