I don’t know 100% about this as my car is a b6 but I know the B7 can read pressure in vag com. But I would think to have that kind of feedback you would need the correct sensor. Also if I’m not mistaken the sensor pick up for that is in the oil filter housing.
Interesting - I’ll have to keep looking. Last Fall I mapped out 139 groups in VagCom to make sure I could easily find what I was looking for. Don’t see oil pressure, just level and temp.
