******************* TURNS OUT THE PREVIOUS OWNER OF THE CAR HAD BYPASSED ONE OF THE BOOST SOLENOIDS**********************
Car goes into limp when pushing 3k+ rpm in 3/4/6 gear. Consistently pulling this 30FE code, what is causing this? I can hear what sounds like the waste gate rattling upon deceleration when the car goes into limp. No tune in car Last edited by vanondemand; 07-31-2013 at 03:27 PM.. |

The only things I can really think of that could cause this would be something with one of the boost-control solenoid valves , or mechanical jamming of the wastegate. Even then, usually it is a 30FF (boost too low) that is stored when the wastegates are mechanically jamming. I've never seen one cause overboost faults.

Unless someone removed/installed the cats in the past, the V-band shouldn't be in the way of the wastegate mechanism. The potential issues mentioned be me and the others are really the only things that could cause this. Now you need to do the legwork and figure out what it is. If you aren't comfortable doing these type of checks, you might want to take the car to someone who specializes in these cars for an opinion.

I can send you a flowchart for vacuum readings at various points in the N54 turbo vacuum control system. It's pretty helpful in determining what the vacuum should be and when. PM me your email address if you're interested.
