Water Pump now oil pressure to low WTF

Glad to hear that you're making progress and that the engine seems ok!

Manually bleeding the coolant system on these cars can be challenging. I struggled earlier in the month at the racetrack to get all of the air out of the system between race sessions.

I am not familiar with the cooling system of the 2007 . If it is the same as the older M96 , it find the black cap near the coolant fill point - with a silver colored wire bail on it. Pull /swing it up to vertical from the stowed/closed/horizontal .
You've been burping it w/o knowing/using this???
I may be wrong so urgently research this ,If a steam pocket develops while you commute , the pressure will vent somehow and the route that steam takes may be very inconvenient
