I haven't been able to find much of anything on these codes together but they came on at the same time. before I buy a new leak detection pump I was wondering if anyone on here has any knowledge on this.

I do not believe they will be related in any way. 2 separate issues. leak detection pump only operates when you turn the car off. 30ff happens when under acceleration.

hopefully answer works for anyone else in the future who has this issue. I'm glad there is finally an answer out their to my original question. I read that the leak detection pump works off of the cars vaccum lines so I had my fingers crossed that replacing the leak detection pump would be the remedy to both codes. Order my Leak Detection Pump from my favorite online store ECS tuning, replaced the pump yesterday(easy fix) info on YouTube, my 335is pump location was on the driverside. This afternoon I deleted the 2 codes before the test drive and drove for about 10-15 mins, hitting the throttle hard enough to build boost and "I have boost again!!!", so far those 2 codes have no reappeared. This leaves my to speculate that these 2 codes are in fact interrelated and replacing the pump will remedy the problem.
I will post and update if the code or codes reappear. Thank you to the only person awesome enough to respond to my post.

Hi,

i got 30FF (and only this one) sometimes when one of my wastegate got stuck open, after some WOT. 30FF just mean that the boost is under target (from a leak or something else like wastegate stuck), and then it disable the wastegate operation to protect your turbos.
