I've had my 2014 in 4 times on check engine light. Showing exhaust system codes. They went through entire DEF system and finally found crystals in or near DEF injector. Replaced injector. Only made it 40 miles before Ck engine is back on. Headed back to dealer this week. Started all this at maybe 3000 miles. 7400 miles now. Thoughts? Others experiencing this?

P20EE code at approx. 3500 mi. Cleared code. Reappeared at 7400 mi, yesterday. I have not been to the dealer. Purchased in September, so no software updates.
I drive this vehicle hard. I'm curious to see how it is after a software flash. The car has little opportunity for anything to get gummed up. I always service my own vehicles, and figured I would take care of most issues with the GC and hoped to never go to the dealer without knowing exactly what the problem is. I did purchase the factory service manual as I have with all my vehicles. (I did try to get an appointment at the dealer today and they couldn't see me for 2 weeks!)
Sorry people are having issues here. Maybe with these issues, put your foot in it every once and a while. No excuses for any of this. The fact that many of the dealers suck isn't helping.

Short Volvo Turbo story: My colleague has a T60 with 172k mi and the dealer says he needs a cat. ($2400). We are going Boston up to Maine and he is going 60 mph. I said let's beat this thing to the client site and see if we can't "fix" the cat. Did a bunch of 40-90 full throttle, he got a bit carried away and went a little over a buck a few times. We did not clear any codes. 2 days later the engine light went off for good. So for an extra 3 gallons of gas we "fixed" the problem.

Update:
The dealer updated the software to address the fault code. I also had a small oil leak around the lower oil pan seal. They resealed the pan, I put the oil filter and oil in the back. They also did the visor recall. They did not reset the oil life monitor and I did find a air box hose clamp that wasn't tightened. (Not a huge deal, it wasn't going anywhere).
They did get me back the vehicle the same day, which I thought was impressive since they were slammed. I have driven about 4000 mi since the flash, it seems to have done the trick. This was my first service visit anywhere since 2002. They were pretty good. I did bring in a detailed sheet of what was wrong including a pic of the oil leak.
