Checking the timing phases (Audi Q5-8R)

Risk of damage due to slipping toothed belt. Turn the crankshaft only in the direction of engine rotation. Turn the crankshaft by the toothed belt bolt 2 turns in the direction of engine rotation until the crankshaft is again close to "TDC". Re-insert the crankshaft stopper "T10050" into the crankshaft toothed belt gear. Turn the crankshaft in the direction of engine rotation until the journal "arrow" of the crankshaft stopper engages in the sealing flange during rotation.

The camshaft hub must be secured using the locking pin of the direct injection pump of the diesel engine "3359". "Pos. 1" and "arrow" are not taken into account.

The fixing point of the high-pressure pump hub can be found with great difficulty. However, a slight deviation of the "arrow" will not affect the operation of the engine.

The tension roller pointer "2" should be in the middle between the tongues "1" and "3" of the support plate. A lateral displacement of maximum 5 mm is allowed. If the conditions are not met, adjust the timing phases.
