No power to start car on 1995 Audi A6 Quattro

I have a 1995 Audi A6 Quatro.It was running fine and one day just quit on me. I have replaced the timing belt, tensioners, crank and cam shaft sensors, ignition module, driver's side head and the mechanic is still telling me that he's trying to figure out why power is going to the PCM but nothing is coming out. I have shelled out all this money for problems that hasn't seemed to be the problem. Please help in North Augusta

you really need a shop that specializes in Audi's. anyone
not familiar with these cars tries to diagnose problems by throwing parts at the car. you simply have the wrong mechanic.
