The CKRA NMS Passat (2012-14) does not have the air-to-air intercooler that causes the condensation/icing problems from the low pressure EGR.
The run lower rail pressure and slightly different injectors than the CBEA/CJAA engines in the G/J/B/A3 too. They do not seem to be as bad about HPFP failures, but those seem to be rarer than the internet might lead you to believe anyway.
The issue the CKRA engines DO have, is they have a notoriously weak turbocharger. This prompted some improvements and a warranty extension for those. They also have SCR, and have had some problems with that system (tank heaters, sensors, etc.). These problems are made worse after Dieselgate. They even have some "bug" in the software that puts the car in unavoidable DEF countdown mode if you drive at 80+ for a while. They couldn't figure out a fix for this at first, not really sure they ever did.
They also have a problem with the heater cores clogging up, mainly due to the increased EGR duty post-Dieselgate fix that bakes the coolant so hot in the EGR cooler that the additives solidify and the next stop in the coolant flow from the EGR cooler is the heater core. There is a TSB about this, but there is not a way to "fix" it, you just have to expect it to need a new heater core every so often (these are not that bad to do, and do not require dash removal).
The DSGs are improved, and work better and are a good match to the much more powerful engine as compared to your BRM.
