1992 Audi 100 Oil Pan Parts and Q&A

• Q: How to remove and refit the oil pan for 5-cylinder petrol engines on 1992 Audi 100?

  A: To remove the engine oil pan, first apply the handbrake, jack up the front of the vehicle, and support it on axle stands. Unbolt and take off the undershield from under the engine, then remove the dipstick. Position a container beneath the oil pan, unscrew the drain plug, and drain the engine oil, cleaning and refitting the plug afterward. Unbolt and remove the transmission front cover, then take out the torque mounting and cross bar. To access the two rear oil pan bolts, turn the crankshaft until the cut-out sections in the oil pan and flywheel align, using a spanner on the crankshaft sprocket bolt. Detach the wiring and hose supports from the bottom of the front suspension crossmember, support the engine's weight with a hoist, and unscrew the engine mounting lower nuts. Support the front suspension crossmember on a trolley jack, unscrew the crossmember front mounting bolts, and lower it slightly. Unscrew and remove the oil pan bolts, then take off the oil pan and gasket, tapping gently with a mallet if it is stuck. For refitting, clean the contact faces of the oil pan and block, place a new gasket on the oil pan, and fit it to the block without using jointing compound, tightening the bolts progressively to the specified torque in diagonal sequence. Raise the front suspension crossmember, refit the mounting bolts, and lower the engine onto the crossmember before removing the hoist. Refit the engine mounting lower nuts and tighten them, then reattach the torque mounting, cross bar, and transmission front cover, tightening the bolts. Finally, reinsert the engine dipstick, refit the undershield, lower the car to the ground, and fill the engine with the correct quantity of oil.
