injector values ?

been reading about possible reasons for the occasional blue / white smoke issue our D3s can suffer with , anyone know what the injectors should be showing on scan tool or other things other than EGR valves ??

when I see the 2 codes together upper limit and lower limit
I worry that the engine has a lack of compression in one cylinder.
Lets hope this isn't the case

Year?
Mileage?
Slightly unstable idle from cold in cold weather?
Does not start as well as it used to?
Notice smoke in following cars mirrors when accelerating hard from lowish speeds?

183k 05 plate , FSH , starts great , runs smooth , no idle or issues when driving other than the occasional blue / white smoke which I feel is down to an injector under performing ??
