Tell me about it.. when you buy a BMW and mods that cost big bucks you don't expect problems like these but hey things happen... now I have to wait on alot of mods like rims, coils, lip and all that stuff as I don't feel confident until I fix this issue.

Any time you mod a car you should expect problems. Doesn't mean you will encounter them every time but you need to be prepared in case you do. |

And yes I agree a boost gauge is a must if you are going to mod along with a scanning tool like the BT one that just came out.. |

It sounds like your car went into "Limp Mode". My 135 was doing the same thing. I would be driving and under very heavy throtle it would go limp and the light would come on which would only enable about 50% of my power. Once I restarted the motor everything went back to normal.
It has to do with your amb temps and which JB3 you have. The JB3 does really bad under 40F with the 1.1 or 1.21. The 1.22 corrects the cold weather problem. Chris |

I just had my HPFP replaced and my problems were almost exactly what you are describing. Once you get the ODBII tool run the diag and see if you get and immanent failure of the HPFP.

Ok here we go.. After using the BT tool to diagnose my car I got 3 codes.. 2 that are the usual DP codes which I am getting new resistors from RR to fix because mine broke from my O2.. but here is the reason why my car goes into reduced power mode and no it is not HPFP.. nor is there any codes related to the fuel pump...
This is the result of why I get it: 30FF: 30FF Exhaust fume turbo charger, low pressure side Error will not cause a warning light Error is not currently present Test conditions have been completed Event 1 Odometer 17664kms 10975miles ambient pressure 997.66 hPa ambient temperature -8.25 °C pressure in front of throttle valve 126.00 kPa speed 3,520.00 rpm So who can help me resolve this or any ideas how to get rid of this issue? Or is this the result of HPFP.. need the technical guys on the forum to chim in..thanks. |

What mods are on this car (all of them)?
That sounds like something is going on with a bypass valve, or something else on the inlet side of the turbo. |

pressure in front of throttle valve 126.00 kPa = 18.274 PSI.
My guess is you got a boost spike because something wasn't doing its job. The ECU thinks there's exhaust gasses getting piped back into the intake maybe. |

RR Scoops RR Plenum RR Oil Catch Can RR Catted Downpipes JB3 1.22 Those are the performance mods on my car. As stated on my first post... this happened after I installed the RR dp.. might not be related but i guess the timeline is right on.. prior to this problem I only had oil catch can, bms single intake and SSTT. |

Does that mean my car is running at 18 PSI once I push my car past 3500 rpm? That'd be pretty insane..

I'd reset it and see if it happens again. If it does I'd start swapping parts back to stock, starting with the oil catch can.
It may just be that something strange happened while the adaptation was taking place with the new DPs though. |

No problem. Let us know how it turns out. I'm pretty impressed with the info you're getting back from that tool. That's a lot more than I get with my generic diagnostics tool. Can you do data logging with it? Maybe set it up to monitor boost, throttle position, and RPM, and chart it out? I know CPE has posted some charts we could compare it to to see what the boost spike normally looks like as the throttle closes. |

bro i dont think the oil catch can had anything to do with it, because i would believe it to come from the tune, thats what we could think of when i talked about it with my guys, so i guess just removing the tune and leaving the oil catch would have been fine but now that you remove both we will see what happens.
well im waiting to see if anything changes.
