It's still under original warranty.. So I'm taking it in about 1.5 weeks so that it can be documented (if they refuse.) and/or repair.
This is preventive measure.....just like preventive medicine. A clog artery may function fine....but overtime function will decrease....eventually....leading to complete obstruction and failure (heart attack).....or in this case....a BLOWN engine.. lol
PLan to to provide M3PO invoice...... I may even take it to Irvine BMW.
