30FF SOLVED! BMW 335i n54 30ff code

On this car, there was a low power issue and a 30ff code stored under high load. Car was only boosting 4psi. After chasing vacuum lines, we found a pinched line going to the turbo against a bracket. This must have happened when the shop was installing the new turbos. So if you’re having a 30ff code make sure to check this bracket along with everything else mentioned in this video. Datalogging is also key for diagnosing issues so always start there when chasing codes. Ensure that your target boost and actual boost are close to each-other and if not start looking for issues! Charge pipes blowing off is another common issue to look for.
