Of course not everything you're told or read is correct. Not even from me! But seriously VW and many other manufacturers use torque to yield or the torque angle method to actually make for a stronger, more consistent connection that can better compensate for thermal expansion.

I have been told that it is better to use 1.9 waterboxer rod bolts in any waterboxer engine, as they are not stretch type, like 2.1 ones are.
