Timing for 1.2 TDI PD

Anyone used VAGCOM to check advance/retard on cam to crank timing for 3 cylinder PD engines?

There is some discussion in USA forums for Jetta 4 cyl PD TDIs.

They call it Torsion measured in Degrees +/-

Hi Lukas,

This data is generated by the camshaft sensor. You can only change the reading by adjusting the camshaft sprocket. First lock the crankshaft with the correct tool and then attempt to lock the camshaft sprocket. If you cannot insert the camshaft tool, you need to re-adjust. Procedure here:

'Turn the crankshaft to TDC position and insert the correct Crankshaft Locking Tool.
Check that all timing marks align and that VS124/V2 Locking Pin can be inserted
easily to lock the camshaft.
If VS124/V2 Pin cannot be inserted - Pull the Crankshaft Locking Tool forward on the
crankshaft gear so its lug is no longer engaged in the hole in the oil seal housing.
Turn the crankshaft until VS124/V2 Locking Pin can be inserted in the camshaft.
Loosen the 3 Camshaft sprocket bolts and turn the crankshaft anti-clockwise until the
lug of the Crankshaft Locking Tool just passes the hole in the oil seal housing. Turn
the Crankshaft clockwise until the Crankshaft Locking Tool can again be inserted into
the hole in the oil seal housing to lock the crankshaft.
Tighten the 3 Camshaft sprocket bolts and remove all timing tools.
Turn the crankshaft over twice, by hand, and return the engine to TDC position, fitting
the Crankshaft Locking Tool.
Ensure all timing marks align and check that the Camshaft Locking Pin can be easily
inserted. Remove all timing tools.'

Ideally the torsion value should be 0-0.5. Details here:

Many thanks guys.

Any idea what your Lupo and A2 read RAB with engine warm after shut down?
 
Lukas,

I think this should be done with the engine running!
