Why do you need variable valve timing in BMW VANOS?
Variable valve timing allows for timing adjustments to be made electronically and automatically, instead of manually by hand like they had to do back in the day. The end result is a smoother power bank, torque on the low end without comprising power on the high end, and overall just better driveability, smoother idling, etc.

Why does my transmission rpm keep climbing up?
It seems that the gears are slipping and causing the rpm’s to climb up. Check the transmission fluid and make sure that it’s full and red in color.
