Renault Laguna 2 1.9dci 120bhp sport tourer - 2.DEF : Coherence between the boost pressure and a - horne65

Please can anyone help?

Having now fitted a new boost pressure valve I have fixed the EGR valve open error but now have the following.

2.DEF : Coherence between the boost pressure and atmospheric pressure.

This is the error code and description that the Renault can clip is giving me.

I have now changed what I think is everything but still problems persist. The car is still running like a bag of s*** and I am sorry to all those people behind me today as I puff out more black smoke than a steam train.

I have been trying all day to re-set the ecu of the error code and going on runs to see if it finally fixes it's self but no joy, Any help at all please, or a secluded spot and a box of matches.

Google this site, the cost of a box of matches would be a waste.
