I've been eyeballing my car(2002 VW Jetta TDI) lately and thinking about this whole EGR delete thing. I had a working "Dynamic" EGR circuit up and running for my wifes 2005 E320 CDI but the EGR emmulation part of the circuit caused strange and erratic shift quality. Now that I know I have the "Dynamic" portion of the circuit down pat I just need to figure out how exactly I want to implement it on my TDI. I have options such as vacuum pressure switch on the N-18 output to the actuator, or perhaps use the relay to switch in the N-18 when cold and out when warm. Once operating temp is met, then a resistor can be substituted in place of the N-18 so the computer doesn't throw a code while the PWM signal can be sent to the EGR emmulator circuit to fool the MAF. There is also the MAF twist mod that may prevent a CEL light when the EGR is deleted too-some have had luck with this method.
