P2002 Error.

[Rossco]

I’ve had the EML light come up on my A4 3.0 TDi combined with no boost. I happen to have my code reader with me and discovered the dreaded P2002 code logged. 
I’ve done sole googling and am getting conflicting reports on EGR fault to DPF sensor failure. 
Is there a definitive answer on this engine?
I only ask ask I’m currently in the south of France - faaaaar from home. 😒
 

I should also state that a month before coming away I had the dpf, intake manifold and egr valve all cleaned and the car has ran flawlessly up until today.

I think the only true solution is to replace the egr and dpf.
