W164 bluetec boost problems
Hey guys I did a blue tec and ad blue delete and now there is a problem with what seems to be the boost pressure in the charge pipes. In neutral when I hold the revs at just under 2k there is a surging whooshing sound coming from what's sounds like the charge pipes, as if the pressure is being recirculated in to the pipe. And when under low acceleration it feels like it stutters and almost like the boost falls off only on partial throttle. When I Matt the peddle to the floor it all seems to right its self for a brief moment then whooshes again making the revs drop around 2-3 hundred revs. Any ideas where is should start?
