[Cam 335i]

My 2007 335i has upgraded Intercooler, vacuum lines, CP, Cone Intakes and BOV.
I was Doing some Logs and Testing my Anti Lag
I pulled 16.1 PSI.

Then my Car began to run without any boost pressure, I initially thought my intercooler piping may have blown off but when checking everything was secure.
The Pressure On my gauge would make it all the way out of the negatives but never over 0 PSI and my car sounded N/A. I attempted to clear the codes but they would instantly reappear.

I turned the car off left it for about 40 mins
hopped in and cleared codes then started it up and drove it. To my surprise my gauges were reading Positive Boost Pressure and my turbos where Spooling Again.

Is there anyway that the wastegates could have been stuck open allowing all air spinning the exhaust side to bypass thus making no boost.

First Pull:
Boost Target: 16.5 PSI
Boost: 16.1 PSI

Second Pull:
Boost Target: 8 PSI
Boost: 0 PSI

I will do a smoke test for any vacuum Leaks when my smoke tester arrives.
But After clearing codes my car seems to be running good again.

Has anyone ever experienced this?

The only code was 3100 - DME: Boost-Pressure Control, Deactivation.

3100 means that the engine detected a malfunction and to protect it and the turbos it keeps the wastegates wide open with no boost target. That's it. I don't know why the ECU decided to shut off the turbos but no boost is what should happen in that case. I guess it's fine if it doesn't happen again.

Edit: I am a bit late since I am just trying to answer all recent unanswered questions but you can just reply and I should get back at you

3100 code appears without any other code?

do not clear codes, drive it (if it does not make funny noise) , rescan.
