The Oil Pump in the Audi TT works under pressure to ensure that engine oil circulates through the bearings, pistons, camshaft lobes and other moving components while also providing hydraulic power to small actuators. Within an Audi oiling system, the Oil Pump section depends on intermeshing gears that draw oil from the sump via wire mesh strainer, send it through the filter and any cooler, then direct it into internal galleries. The relief valve opens as pressure readings exceed specification to provide steady pressure flow. At idle, oil pressure is at its low point and rises with rpm. A threaded switch or sending unit exposed to the galleries activates a warning lamp or gauge when pressure drops dangerously low. In the process of Audi engine rebuilding, the housing, gears, gear-to-housing clearances and pickup tube are checked thoroughly to ensure that they are not scored, nicked or filled with junk. The relief valve must be free and the screens cleansed to prevent restriction. The requirement of change is due to impediment in rotation caused by wear to the driveshaft hex or, alternatively, the gears, chains, sprockets or a driveshaft hex. The proper pressure can be approximated at ten psi per thousand rpm. It depends on bearing clearance, oil viscosity and temperature. It can be either excessive or insufficient. Both can cause damage and are more severe than overheating. Engines that yield high output with wider bearing clearances occasionally have one fitted with a higher volume pump for supply. The Oil Pump performs a critical balance. All Audi powerplants receive dependable lubrication from the Oil Pump. That means the TT model range is offered the same protection as every TT engine Audi makes.
