Replacing Turbo Lubrication Hose

Model: Audi A6 MK 2, C5 - Years 1997-2004
Part: Engine oil

Turbo lubrication is absolutely essential due to the high RPM; additionally, the oil also acts as a coolant to prevent excessive overheating that could compromise functionality. The shaped hose that delivers oil to the turbo consists of two fittings, one that attaches to the base of the oil filter and the other to the center of the turbocharger; these two fittings, which ensure oil flow, should then be secured with two bolts to which a new copper gasket must be applied and tightened with a torque wrench.
