OK
Now I would bring up the HFM single again, wait 2 secs , hold button for 5/6 secs , turn off key for 50 sec , back On for 10 and start car.
That will Reset HFM Memory to mean for adapatation . [ Nothing to do w/code retrieve]
Then just drive and wait for codes, if any........
I think you already know this , if so, forget I mentioned it......

I would expect that they would have reset to mean after fixing the vac leakage, but maybe they just fiqured it will re-adapt after a few drive cycles anyway .. knowing you were driving around with false intake air all that time, I personally would have immediately reset the memory, for sure.
The problem with using drive cycles to reset adaptations is that while the Drive Cycle process is going on, the Diagnostics modules can still be picking up false codes b/c the specs are still out of norm. By resetting manually after a repair/remedy, you don't have this time lapse to contend with .............[ and it only take a min. to do anyway]
