IMO, this TB job is not that different than any other TDI:
1. CR engines are DOHC, which are a pain for space to work in the engine bay
2. CR engines have a HPFP, but the pump doesn't really need much fiddling around, not like VE pumps (never had a VE engine). Also, there is no torsion value to fiddle with either (PD engines)
3. Not sure for CVCA (Passat), but for CRUA (GSW), the motor mount needs to be disconnected, same as for BEW and BRM. Yep, also for CVCA.
Otherwise the procedure goes like this (more or less):
1. Jack the car up from the passenger side, and change to a jack stand
2. Remove the splash shield from below engine bay
3. Remove right side wheel/tire, and inner fender cover
4. Disconnect the several brackets and one clamp (DEF injector)...this is what takes a lot of time
5. Remove upper TB cover
6. Support engine. In this case CVCA/CRUA, the oil pan has a plastic cover, so supporting from bottom with a jack won't do, you'll need to support from the top...plastic cover can be taken off
7. Remove passenger side motor mount and bracket (new, one-use bolts should be included with the kit)...I usually need to raise/lower the engine to get the bracket out
8. Remove serpentine belt, harmonic balancer (bolts might strip), lower TB cover, upper TB cover
9. Find TDC, lock crank, lock cam, lock HPFP
10. Remove tensioner, remove TB, remove water pump (WP), remove rollers
11. Install new WP, new rollers, new tensioner, new TB
12. Tension TB, rotate engine twice by hand, to make sure timing wasn't somehow lost
13. Close it up and fire it up
14. Pat yourself in the back
