Ugh, yeah good luck. Never reset that code, or any SCR efficiency codes. Just drive around with the CEL on until the car turns it off for you. Then go in and clear the memory.

As for what to do now... you're going to have to run through the SCR/DPF system testing. Get a "pass" from ISTA and then go for a ~40 mile drive >60mph. Then the DDE should turn off the codes for you.

I just got my DDE/CAS/Key back from a service because the DDE had locked in no start after reaching mileage countdown (+ 1 50mile reset). I had failed NOX sensors that complicated things which is why I ran out of mileage.

Good luck. Keep the thread updated.
