Hey guys been having some problems with the nav.. it blows white/blue smoke when idling and pulling up at lights. Been to a few places and can’t seem to find what’s going on. Recently put a new exhaust on but no tune yet.still had the same issue with the standard dpf though. It is going for a tune within the next couple weeks. The engine keeps making oil wondering if I have a fucked injector or if the tune will stop this issue. No engine lights, no codes, and no loss of power.
 
if its making oil, which might smell of diesel, it could be trying to regen the dpf all the time due to a sensor issue. a tune might fixed that if it disables the dpf regen.
had a similar problem with another diesel where it had dpf removed and tuned, but service guys accidently overwrote the tune and it started smoking.

otherwise turbo is a common suspect and also blowby.
