You can change the oil pressure switch from the top.
Remove the 2 screws from the coolant tank and move it over toward the radiator. ( don't forget to unplug the sensor on the bottom of the tank)
This give you clearance to reach the switch. I believe the deep socket is 24mm. When reinstalling put some paper towel in the socket to help with installation. Other wise the switch will be pushed into the socket when trying to reinstall.
Use a BMW switch, it is about $20 bucks at the dealer. ( It centers the o-ring on the switch to prevent leaks). I installed a $8 aftermarket one and it leaked. Hope this helps!
