E82 135 n55 intake pipe question

[Cyruz143]

Hi all.

Cars thrown a few codes for intake pressure. I think I've found the leak but I think I'm missing a gasket. If anyone has recently removed this part of their intake and remembers what went where can you chime in.

So where part 10 would be (a hose clamp) I have a torx bit that mates these two plastic pipes together. When I took them apart there's no seal in there so I can't imagine this was ever air tight to begin with! Train of thought tells me someone has left out a seal at some point. Anyone confirm?



I think that perhaps I should have either: https://www.ecstuning.com/b-genuine-...t/13717599292/ or https://www.ecstuning.com/b-genuine-...t/13717599291/

Pre-turbo will always be under vacuum, so not boost leak.

The screw is correct, it ties the upper and lower intake tubes together, with a ribbed gasket on the lower, male part of the connection.

Perfect, it's the lower half that's missing it's gasket I believe.

Also yes, not a boost a leak, vacuum bringing unmetered air in!
