Major parts have already been replaced including the turbocharger, oil cooler, water pump, turbo lines, radiator hose, thermostat, and valve cover gaskets.

Light indicator showed low coolant levels. Car was leaking coolant slowly. Filled up coolant but levels continued to go down. Brought to mechanic and they had to remove oil filter housing to replace failing gasket. Car is about 113K miles.
