After I pushed it to where I needed to work on it I checked codes and got:

P220E - NOx Sensor Heater Control Circuit Range/Performance Bank 1 Sensor 1
P24AE - Particulate Matter Sensor Circuit
P2BA9 - NOx Exceedence - Insufficient Reagent Quality

Next I jacked it up and removed the SCR METERING UNIT to check and clean it (as Brent Dalton did (posted above)). Mine was not too gummed up but I cleaned it and reinstalled it.

I then cleared the codes with a cheap code reader and it allowed me to start the engine. However, it again displayed an "INCORRECT FLUID - NO START IN 80kms". Apparently from what I read these additional kms can only be generated once without using ISTA software. So, I drove it about 44kms hoping it would clear itself but unfortunately that didn't happen. I tried disconnect both batteries overnight hoping that may clear it but no luck there either.

Next, I'll try and get a version of ISTA and a windows laptop (which I don't own) to try to further diagnose issue and clear the no start condition. It will NOT go to the dealer if I can help it :-)
