[CDG]

Thx Beav, you are correct:
the 1 old code and 2 new codes I'm getting are:
34: 'EGR solenoid or Circuit'. I have had the this code for over a year, and have never tried to resolve it.
28: 'Knock sensor No.2 (SVX left side)' new code
37: Oxygen sensor (No.2, left side on SVX)' new code

I tried to clear these codes from the ecu and could not, so I suspect I'm either not doing it right, or they are completely dead(shorted/open or missing)
