I've been trying to track down my 30ff code for some time now. It occurs at wot every time. The 30ff is the only code that pops up with it but one time I noticed a code was stored in the same. I can't remember what code it was but exhaust vanos solenoid mechanically stuck. I can't get this code to come back. I was gonna clean them before replacing but like I said they don't come back. I have a bt cable and just purchased mhd for datalogging. I have the csv file here hoping some people might be able to point me in the right direction. This was a 4th gear pull onto the freeway. Pull is later on in the log.
