I recently put a TDI-specific in-tank pump in my 2001 Audi A4 with transplanted BHW to replace the old high pressure pump. Before starting the engine, I ran basic setting 035 to run the pump for 30 seconds and prime the system with the engine off. I have a 15 psi fuel pressure gauge on the line to monitor pump activity. To my dismay, when I ran basic setting 035, the gauge got pegged way beyond its max! The gauge ended up being damaged as a result and now rests at 6psi all the time.
So I switched out the gauge for a 200 psi diagnostic gauge and ran basic setting 035 again. Lo and behold, the gauge comes right up to 90 psi!!! That's the kind of pressure I'd expect to see from a gasser pump, not a diesel lift pump. Am I doing something wrong???
This is the pump I ordered and installed:
