Hello:
I am trying to solve my problem check engine light. I am getting a P0402 code "excessive EGR flow". I just replaced the egr valve today. I had also changed the glow plugs because I had that error prior to this latest one. The code came back on. Do I need to now change the pressure converter for an A4? The mechanic I'm working with is unformiliar with the tdi, but is honest in helping me solve the problem. He replaced the valve today and cleaned and vacummed the line. The light was off until I was a few miles onto the highway. I'm running a 2001 TDI with 100,000 miles as of yesterday.
Thanks!
