I have the following faults on my disco 5 currently. All cleared ok but after starting off, at next junction, car is lethargic and then races away with itself. This is intermittent. It happened just after adding adblue to car. Any ideas as local garage unsure.

How many times each fault has occurred, ie once could just be a blip, more than once means there could be a genuine issue.
 
It’s a 2018 2litre. It started after adding adblue a while back and engine management light came on and disappeared after a good run. This time after adblue addition after a couple of days engine sluggish as I said, then fault codes appeared as in picture. It’s intermittent. Not sure if it’s adblue injector, NOx sensor or something more sinister.

You will probably need someone or the kit to read the live data, ie to see what the sensors, nox/map etc are actually seeing, it does not always mean they are at fault, as there could be an issue upstream messing up what the car expects to see.
 
The last DTC P006A-84 is the one relevant to restricted performance, it suggests an induction leak, possibly from a poorly fitted air filter or pipe. How that correlates with AdBlue, I have no idea...
 
Also, the other three (NOx limits & emissions / SCR supervisory) are most likely consequential or 'cascade' DTC's due to unmetered air passing through the intake and exhaust.
