Timing phase correction (Audi Q5-8R)

If the camshaft hub cannot be locked, remove the crankshaft stopper "T10050" until the journal releases the hole. Turn the crankshaft slightly past "TDC" in the opposite direction to the engine rotation. Slowly turn the crankshaft in the direction of engine rotation until the camshaft hub can be locked. After locking, loosen the camshaft timing belt gear bolts. Journal A of the crankshaft stopper "T10050" is located to the left of the hole: Turn the crankshaft in the direction of engine rotation until the journal of the crankshaft stopper locks in the sealing flange when turning. Tighten the camshaft timing belt gear bolts to a torque of 20 N·m. Journal B of the crankshaft stopper "T10050" is located to the right of the hole: First turn the crankshaft slightly against the direction of engine rotation. Rotate the crankshaft again in the direction of engine rotation until the crankshaft stop journal engages in the sealing flange during rotation. Tighten the camshaft toothed belt gear bolts to a torque of 20 N·m. Continuation with correctly adjusted timing: Remove the locking pin of the direct injection pump of the diesel engine -3359 from the crankshaft "T10050". Turn the crankshaft by the toothed belt bolt 2 turns in the direction of engine rotation until the crankshaft is again close to "TDC". Repeat the check. If the camshaft hub can now be locked, tighten bolts "1" of the camshaft toothed belt gear to the specified torque. Tighten bolts "2" of the high-pressure pump toothed belt gear to the specified torque. Repeat the timing phase check.
