2009 n54 135i Rear Duct

bxsinster · 03-17-2014, 05:10 PM

I had my car in for headlight bracket replacement I get a call from bmw stating my intake rear duct supposedly for my turbos she claims is leaking air, part number
(13717556550). And they quote me a price of 460 dollars. I checked and found the part to be only about 96.00.. I was thinking of doing this myself I believe it is the hose behind the intake box checked on realoem, I looked on Google to see if anyone tackled the job but couldn't find anything. If anyone has any advice or has done this before or a DIY or anything would be great.

To replace this you need access to the rear turbo which means your downpipe has to come off... Which explains the $400...

Looks like they broke the charge pipe where the diverter valve plugs in. If they don't fix it (which they should), it's a pretty easy install. I'm surprised you don't feel a serious drop in power, and see a yellow half engine light on your display. You're definitely loosing boost.

bxsinster · 03-18-2014, 11:03 PM

funny cuz i feel a verry minor drop in power and no check engine light. i guess maybe cuz only one diverter valve is cracked off? yea im gonna stop by tomorow if a snaping belt cant cause this i feel like they leaned on it with there hand or something, and i want to see if its the charge pipe or the rear duct hopefully just the chargepipe

ended up being charge pipe only.. they gave me the wrong parg number which led me to believe rear duct was bad

Broken charge pipe? Time to upgrade, if your tuned only a matter of time until the factory one breaks anyways
