As to posting pictures, the fan is in the car, I'm not going to tear it
out just to post pics. And pics aren't likely to do much to solve
the question of what exactly failed.

"So when you decided to get rid of the X and sell it to a new X owner are you going to replace the DISA valve and Aux Fan? Probably not and probably won't tell the new owner about these two problems. "

And there you go again, with more totally unsupported personal attacks.
Is that what this forum is about now? As to lacking power in the
mid-range, you're once again in over your head. I've seen absolutely
no noticeable difference in performance with the DISA working or
disabled. I have seen others here report the same thing. Are you
going to personally attack them too?
