got a 2011 Jetta TDI 2.0L with a p0403, I Replaced it,
First you do not offer a good reason / explanation for replacing the EGR Valve.

Look in Groups 003 & 035. Your MAF and EGR Actual & Specified are way off !!


I would put the old EGR Valve back on and start again with this.

001699 - Sensor Reference Voltage "D" P06A3 - 000 - Open Circuit - MIL ON
Why skip this ^^ It is enough to put the MIL on !! I would give that some attention !!
