Needing some advice please

[KDD]

Hi all,

I would really appreciate a bit of advice. I have a 2014 TDI. In the past year I’ve replaced the B pump 3 times (twice was apparently due to garage incorrectly fitting it). The last one was done 5 months ago by an Audi specialist. Since then the turbo went so that was fully replaced and a new EGR valve fitted by the Audi guy (less than 3 months ago). Today I went to start the car and the glow plug light starts flashing and the engine management light comes on shortly after. I checked the codes which are: 

P261C - surprise, surprise b pump issue 

P2426 - EGR valve - control circuit low 

P0047 - turbocharger boost control solenoid A circuit low 

Does anyone happen to know how all three issue which have only just been fixed can be coming up again? 

Many thanks in advance 

KD

Does the pump have to be coded to the car and if so has this been done correctly? 

Regarding the egr what kind of driving do you do, could it be blocked again?
