stock n54 100k+ miles cobb = 30FF

djpeetur · 06-30-2014, 01:47 AM

I went ahead and took off the cobb on my 2008 135i. When i drive i get the dreaded 30ff code but no limp mode. Did a smoke test and it seems to be holding pressure fine. what should i change with 100k miles. Charge pipe? Dvs?

i can drive my car regularly even with the half engine sign. just annoying any ideas on where to start ?

How much pressure did you apply when doing the smoke test?

It's probably your chargepipe/DV's. If not, check your vacuum lines. They're prone to failure on both stock and modified vehicles.
