Can someone help me out with my turbo lower inlet hose?

E90joee · 07-08-2018, 03:49 AM

For some reason I don't have a screw where it should be to tighten it down, but thats only on one side how would it secure on the other side?

its hard to see from this angle but on realoem it shows a hose clamp holding it together but I can't find anywhere a decent pic to illustrate it besides a diagram.it seems like the screw makes both sides tighten but there is no groove to put the band in so im stumped...ive been having this whooping noise for almost a month now and after reclaiming all my hoses from FMIC I finally figured the problem only to be a little confused...hopefully someone can help...any pictures or input will help thanks

Maybe it's me, but I'm not sure what your issue actually is. The pipe that goes into the turbo has a screw/bolt that holds in down on the turbo side. Then there is a screw you seem to be missing that connects the top plastic pipe to the turbo inlet pipe. A screw goes in that hole in your pics and screws into the inlet pipe fitting.

This is not a section that is likely to cause issue as it would be under vacuum, not pressure, when driving.

I see, on MHD the code pulled up was 2906 which says- "intake plenum: suspicion of leaks between exhaust turbocharger and intake valves"

also, 29d8- intake air temp- charge air temp, comparison: intake air temp too high

just thought since this was leading from the intake it might of gone hand in hand.

2906 would be a boost leak. Code sheet says it could also be a bad pcv valve leaving. Both of which would ne be related to pre-turbo plumbing.

Since you are getting 29D8 as well, I'm guessing you have a bad TMAP sensor.

There is only one bolt that holds the intake pipe to the turbo inlet pipe. Other than that there is a rubber grommet that helps create a seal.
