Yes, that could be it! And that agrees with the attached DISA test procedure which also points to the DME.

And IF it is a DME/software bug, there could be many vehicles out there with undetected inoperative DISAs because there are no obvious symptoms (mine doesn't have any).

Do you plan to try to reprogram?

For the interim, would it make sense to lock the DISA in the closed position to give the best overall performance? (most driving is done under 4000 RPM when DISA should be closed)

So where do things stand with the DISA?

Excellent thread. Lots of info but I haven't seen a conclusion. I have the same exact problem with my DISA. Did the original poster identify the issue as a faulty DME? Also, how did you identify that you have a Euro 2? Help please!!!

I've tried three different software flashes and they all do not close the DISA at idle. I've confirmed it works through the DIS test which actuates the DISA. The DME is fully capable of opening and closing the flap, it just isn't programmed to do so at idle. Weird right!?
