I had the exact same 2 codes read on my VX yesterday, did the cleaning, 3 times now on 3 different occasions, and the light has come back on each time. The plunger moves up and down freely, and the egr tube inthe intake manifold flows intake cleaner and is not plug. Is it just a bad egr solenoid, and where do you get o ne other than the dealer, cost???

Hope just the cleaning works for you!

Thanks!
