Fault codes popped up after engine management light coming on

[Superpie747]

Hi all so Van went haywire today engine management came on then urea and triangle with exclamation mark in centre of it also 700 miles till no start warning..
Plugged a fault reader in and came up with:
P20F6
P20EE Stored
P208E Pending 
P20EE Pending 
Anyone any ideas ??
There was a slight bit of blueish white smoke from exhaust and a slight bit from under bonnet.

Hi there.

There are no codes in the official documentation with letters in them, no idea what your code reader is pulling those from. All P codes are engine related and all only contain numbers.

P20xx all relate to cat & emissions, but with the Urea light being on, normally you are low or out of Adblue. Try sticking 5L of the magic juice in.

It's possible the Adblue pump / injector has left the building...or there is a problem with the Eolys pouch / pump / injector - best idea, get it scanned with proper Citroen software (DiagBox) as a generic code reader is next to useless on these vehicles. I would try the Adblue top up first though, before trying the dramatic options.

These codes are more likely (original OEM data) and are the only 3 codes starting P20

P2031    
Temperature downstream of catalytic converter signal : Implausible temperature before starting the engine  
P2032    
Temperature downstream of catalytic converter signal : Short-circuit to earth, or value too low  
P2033    
Temperature downstream of catalytic converter signal : Short-circuit to positive, open circuit, or value too high

I've attached the official code list for the 1.6 HDi engine below: (for EDC16 ECU but the EDC17 you have will not be much different)
