Good news, ladies and gents.
in case you were dreading that code 34 (EGR Solenoid circuit) and can't find a good replacement?
Well, they ARE still available, even though most parts houses tell you they aren't.
Cheapest I found was Amazon, $47. Brand new, OEM Hitachi, same part numbers, stamps and even wire colors.
Hitachi SLV0001 or 14774 AA101 (on the box)
Amazon had number W0133-1624136.
Pics to come later.
