How to remove BMW 320li oil pressure regulating valve

The disassembly method of the oil pressure regulating valve is as follows:

First, open the back seat, remove the upper cover, and then unplug two oil pipes and power plugs.

Tighten the plastic cover with a wrench, and then screw it out slowly. The original one was tight. If you twist it hard, the clip may break, but there are many clips in a circle, so it's okay.

Now slowly take out the gasoline pump. Be careful not to break the float when you take it. There is still gasoline in the gasoline pump. Slowly take it out sideways and pour it while holding it.

After the gasoline pump is taken out, the bottom is the gasoline regulator.

The oil pressure regulating valve is mainly used in the lubrication system of the engine, mainly to regulate the oil pressure and limit the lubrication system. If damaged, it will cause a low oil pressure alarm.
