C4 Cactus 1.6 Blue Hdi error P2566

Unread post by Cactus owner »

Hi, can anybody give me an advice, what to change or check for the P2566 error. The car runs normally, maybe a little increase in consumption of diesel..app 0.2l for 100km
OBD scanner shows the : TURBOCHARGER Boost Control Position Sensor A Circuit Intermittent
Only that error. Where is the position of this sensor? Thanks for any advice.

Is that a euphemism for having the Adblue system coded out?

If it isn't, what was done to repair the system?
