325 oil pressure light

[agent006]

How quickly does yours go out when you start the car?

I ask because mine seems to be taking longer. It goes out just as the car settles down to idle, about 2 or 3 seconds or so. Not a huge amount of time but if it's a sign of impending doom i'd like to get on top of it ASAP. For the moment i turn the engine over for 5 seconds or so to get the pressure up a bit before putting the obc immobiliser code in, then start up. Light is OK then and goes out pretty much as the car fires up.

About 3000 miles ago, with a genuine BMW one.

Doubt if that's the problem then, but a new one would be an easy and cheap thing to try.
Next cheap and easy thing would be a new oil pressure switch.

Oil pressure switch it is then. Where, how, and other such questions?

[Brianmoooore]

Just above the sump top, front right side of engine, Remove connector, unscrew.

I assume this will involve a fair amount of spillage of the sump contents, or is it above the oil level?
