Does it have a terrible idle if you let it go below 2500 and slowly stalls out? If so then it could be your intake manifold gasket.

Vacuum leak
EGR valve (if it is an S4)
Clogged primary injectors
Plugs, ignition harness, timing

1. check for vacuum leaks (google for various techniques)
2. check for trouble codes
3. EGR operational check
4. ?

Well done. What was the fault with the regulator, and what was the fuel pressure that you saw before fixing the regulator?
