omt,
I've been around that block many times. Unlike you, I will not walk in lock-step to the demands of VW and quite honestly, a portion of my business is to re-engineer the mistakes that VW has foisted on the public, such as our PD cam improvements.
I do not begrudge your interest in replacing bolts that are overkill, however in my extended experience with those particular bolts, I would have to see the first one fail before I felt the need to change my position. To put it bluntly, I don't see that happening. I've been ignoring their demands on that set of bolts for almost as long as the engines have been in the marketplace; which amounts to almost 20 years.
We also modified the torque spec for the ALH/ AHU cam sprocket torque to 45 ft lbs, as we think it's ridiculous to have a 14mm bolt with only 33 ft lbs torque, expecially when you see a newly installed cam sprocket slip and ruin a cylinder head. We engineered the replacement bolts for the PD cam caps and Rocker shafts. After all, a 12 ft lb torque-to-yield (TTY)bolts are nothing short of ignorant, and only for the advantage of VW manufacturing to simplify their assembly process.
But that does not mean we reject all TTY bolts. The hold down bolts for PD injectors, engine mount bolts and the big roller bolt for an ALH timing belt kit demand their replacement. We just try to use common sense when considering the reality of these bolts and the engine they hold together.
