From looking at data files seems your DDE already has a latest firmware.

Regarding broken bolt I would first try the bolt extractor tools. Bolt is hollow so you don't even need to drill, just insert the tool and turn it counter clockwise... No need to remove manifold either as it looks like there is plenty of space for the tool. Spraying it with "cooling spray" (not sure how that thing is properly called in english, but it's a spray which cools the part you are spraying to like -50°C so it thermally contracts and loosens, I use one made by Wurth) probably would help too.

P.S. you should really check live data whether you are getting proper readings from the intake air temperature sensor (which is integrated in mass air flow sensor). Freeze frame shows it's reading at -50°C which is CLEARLY a problem, but I always double check as my experience is freeze frames are not always exactly correct on these old cars. MAYBE it could even cause this pressure fault in the case DDE uses that value to somehow estimate allowed discrepancy...

P.P.S. Otherwise it looks like some kind of transient fault which exists for an extremely short time so DDE registers it, but by the time it does that, measurement is ok again. But it may as well be a wiring issue. I would first check the wires between that sensor and DDE for signs of rubbing. So AFTER you fix intake air temperature and see no issue with wiring, I personally ONLY THEN would try replacing this pressure sensor. Maybe it could help you. Good luck with that if you try...
