2005 a4 quattro base sedan: starts and idles fine and continuous but stalls when trying to drive. no codes, no CEL, new fuel filter, good fuel stream at fuel rail at start 55psi and 60 psi while idleing. WTH!!! anyone know why it stalls at take off?

 

Found the problem: diverter valve was separated at the threads. It would move back and forth opening and closing when given throttle.

 

It really is a beautiful car! Thanks for the great walkthrough because I haven't found a video yet that shows everything and I'm considering buying one!
