Hi thanks for the add, I have rebuilt a 18 plate boxer dw 2.0 hdi addbluen engine that had been in water ceased belt tensioner dropped belt rebuilt head one new rod

all is good apart fro p00bc21 and po2ed21 air circuit air flow higher than theoretical air flow after sales threshold other code is lower than...

Smoke tested air side new egr took back to main agent said crank casse pressure to high due to valves? doesnt make much sense ,i have done relative compression and looks to be ok drives ok but when hot and you lift foot off and coast light comes on.

had nox sensor issues due to tank having a hole in it now sorted flashing milage but radio has been out.


Dont really know what to do with it.

any pointer would be fantastic!!

Cheers



Max
