part 2, setting up for a tdi application is identical to setting up for reverting back to standard.
in short you need to to the following (Penbryns work not my own, thank him for the info)
How to set-up the wastegate actuator for the TDI motor:
a) Remove the circlip from the wastegate (A).
b) Open the locknut on the actuator rod (B)
c) Remove the actuator from the wastegate (C)
d) Loosen off the rod until the 'hole' fits easily over the (closed) wastegate lever (C)
e) Remove the rod from wastegate again and turn it 8 turns clockwise.
f) Refit the rod to the wastegate, tighten the locknut, and refit the circlip.
With the ABL engine you really need to get a boost gauge to do it properly as the boost is controlled by the resistance in the actuator spring alone. Stock for the ABL is 9psi but 13 is quite safe to run without an intercooler fitted.
