Re: [DML] Control Pressure Regulator/Twin Turbos [long]

Hi Dave

As stated in my original mail, the CPR in question caused the same 
symptoms in my car. Replacing it fixed the problem. My question really 
related to what this thing does (well, okay, I know what it does, but 
I've little understanding of HOW). And why this apparently spotlessly 
clean unit could cause a massive blockage. I took it apart, cleaned and 
blew it out, but can't see how it actually works!

The fuel filter has been replaced, yes.
