hi everyone,
Got a Vauxhall insignia 2.0 Cdti ecoflex, 2015 model.. scanned the car coming up with the code P0299 engine underboost, this only occurs when car goes over 3500 rpm in any gear..

I have looked into all the sensors replacing some and cleaning others as from the picture it’s reading red number for the fuel rail pressure sensor but replaced the one on the fuel rail it’s self but does it have any more as lists two?

Any help would be great cheers
