    Download the SIB linked in my post above.

    A few M54-equipped models are affected, E46 and others. Early E60 530i, early Gen 1 Z4 3.0.

    3.0L M54 only, not the 2.5L. And man-trans only.

    According to Jim, it's only cars with MS45 software... But apparently SIB says otherwise.

    On mine it did it in 3rd too but it was more noticeable under acceleration in 4th, 5th and 6th. And like you said, more noticeable going up a hill, or even into a good headwind. I assume it might have done it in the lower gears too but the engine ran through that 2800 to 3000 rpm range so quick that you just didn't notice it.

    I have M54B25.

    Assuming I am spared from the dip blues according to that SIB.

    You should be un-affected Oli.

    What it says to me...in a nut shell is......"blah, blah, blah....you're going to be without your car for a month, blah, blah, blah....."

    I've copied the SIB here....

    I suspect the only reason it says to send the DME to Jersey is because the SIB is so old (fix might not have been rolled out by that point). Unless there's a hardware change, I don't see why flashing the software in-house would be an issue. Latest software is circa 2008. On my old ZHP it did nearly eliminate the 4k dip issue (well it was detectable on a dyno, but every 330 has that)

    I would like to see what a Jersey-flashed DME reports itself as. If it's the same hardware/software that dealers can flash in-house today, then there's probably no real benefit from having it sent to Jersey and paying $500+

    I'm not sure why it needs a PUMA case and sent to BMW NA for programming but I did have it done and I'm uncertain of many things it did. it supposedly removed the dip from 3k but I also noticed my DISA Valve is now always open when the car is running.

    Whad do you mean how it reports itself? I have the DME updated so what information would you like me to pull? I can try and pull it off at work.

    Meaning yours was sent to NJ or just re-flashed at the dealership?
