Well, I picked up the TDI EGR cooler, so I guess this is now a project.
Now, I need an EGR valve. I need a large EGR valve to ensure it will flow as much as I want. I also need a way to control this EGR valve. There seems to be two kinds of EGR valves, vacuum actuated, and solenoid actuated. Suggestions are very welcome.
