• Dial Gauge 0-10 mm (VAS 6079)

- Remove timing chain upper cover. Refer to => [ Upper Timing Chain Cover ] Upper Timing Chain Cover

- Remove the noise insulation.

- Turn the vibration damper, from underneath, in direction of engine rotation to Top Dead Center TDC.






• Use a ratchet with a 24 mm socket to turn the vibration damper. Always turn vibration damper in direction of engine rotation to TDC. Do not turn the vibration damper backward to get to TDC!

• If the arrow marking on the lower timing chain guard is no longer visible, set the engine to TDC with the (VAS 6079) => [ Positioning Engine at TDC with ] Positioning Engine at TDC With Dial Gauge 0-10 mm (VAS 6079).

• The notch on the vibration damper and the marking on the timing chain guard lower section must be opposite one another - arrow -.

• The markings - 1 - on the camshafts must point upward.

- Measure the distance from the outer edge - 1 - to the marking - 2 - on the intake camshaft.






• Specified value: 61 to 64 mm.

- Once the specified value is reached, measure the distance between the marking on the exhaust camshaft - 3 - and the marking on the intake camshaft - 4 -.






• Specified value: 124 to 126 mm.

• If one tooth has an offset, there will be a deviation of approximately 6 mm from the specified value. Install the timing chain once again if there is an offset.
