What goes on this port?

[RichHawk]

Hello mini peeps!
Richard here, former 911 regular pelican troll. Tonight I picked up an 07 Cooper S R56. 139k miles, 80k since getting a new head. It runs and drives but is throwing code 2885 the irregular boost code. The former owner replaced the turbo, the housing with waste gate, the valve cover and the vacuum lines. None of which fixed it.

So up on the lift, and just poking around the pressure converter area, and I notice what looks like an intake port that doesn't have a hose on it. Is is supposed to?




This picture is from underneath the car looking up at the intake. You can see the big line coming from the intercooler into the throttle actuator on the right side. The mystery nipple is on the left shown just above the pcv hose.


I also snatched a picture from the Internet of an intake, so you can see the nipple there as well, just above the pcv attached hose.



Thanks for your advice!
Richard

Ah ha!
Someone else asked the same question (On the internet, you are NEVER the first person)

Missing Hoses? - North American Motoring

Not used, and internally blanked off. It sure would be good to confirm that.

Congratulations on the purchase of your R56, Rich. These are some fun cars, especially turbocharged. Yep, that thread is correct and you should just make sure the nipple is sealed.

As for P2885 - Boost Pressure Control Deviation, plausibility

Since the new head was installed, was a carbon clean up ever performed? You'll want to keep up on this every 50k to ensure you're getting every bit of HP out of your N14 engine as you can. I've seen this code thrown with some individuals who ended up needing to do a carbon clean up. Info on that here: http://www.pelicanparts.com/techarticles/MINI_R56/88-ENGINE-Turbocharged_Engine_Carbon_Cleaning/88-ENGINE-Turbocharged_Engine_Carbon_Cleaning.htm

I'd recommend checking every boost pipe and vacuum pipe that you can to rule out a possible vacuum leak. Also, I know you said the previous owner replaced all of these items, but I'd still test the wastegate and wastegate vacuum actuator. Check your turbo seals as well. You can follow the instructions in this tech article here: Mini R56 Testing the Engine Turbocharger Wastegate | Pelican Parts DIY Maintenance Article. Also, what turbo did he replace the stock one with?

Rich - did you ever figure out what was causing your P2885 code?
