Help any input
1st BUG: Dealership reset airbag ligth them and told me it was possibly my battery and the 800watt amp that is only putting out 400wats @4 ohms is the reason why. Long story short light never came back on. Then battery died 8 months later (1st cold day in VA). Replaced battery moved wheel from left to right.Everything was good...
2nd BUG: 2 months down the line topped off with castrol fully syntehtic oil.. now X engine oil temp wont go to center line if doing highway driving or higher than 45mph stays at first line from center line. Any slower than that temp stays at center line.
3rd Bug 2 weeks ago picked up a friend in the X he weighs around 6ft 5 and 290. As he was getting out my "SRS" and "passenger side airbag off light" came on and wont turn off now...
Can the weight of a passenger damage the sensor..

I tried resetting it using bmw scantool 1.4 but it says faulty voltage present in shawdow memory

I'm scheduled for maintenance appointment in FEB I have 2 green service intervals still.. I'm scared should I push up the appointment.
