The TDI Timing Checker works only as a “plug-in”. You must start it using the [TDI Timing]
button in VCDS. Starting it any other way will result in error messages and it won’t work.
Note to PD (pumpe duese aka unit injectors) and CR (common rail) owners: The
timing in PD and CR engines is determined electronically by the ECU. There is neither a
need nor an ability to check timing on the PD or CR engines using VCDS. There are no
graphs published for the simple reason that the timing is set using a dedicated VAG locking
tool when changing the timing belt :-)
Version history and source code for the TDI Timing Checker can be found on our website:
