weird one, oil light, level fine, no codes?

[gttjames]

right people hoping you can help. Got a 2001 my 1.8t golf, oil light came on, so checked oil level, was on dipstick still but a 1/2 litre got it back upto 3/4 - light didnt go. Thought it would reset itself, it hasnt, so plugged in box i have and no dtc's stored, not even the common dv code?

On start up it beeps and says 'check oil' - been like this a while now and runs fine etc???

They do fail from time to time; mine went it my TDI

What colour is the light?  Yellow normally means level; red = pressure

I had this the other day I'd accidentally snapped the wire on the sensor to the right of the oil cooler believe its oil pressure sensor try that I may be wrong but hey give it a go what's the worse that can happen

Just an update here, might help overs in the future.

Replaced oil level sensor, no change. Had a chat woth seat next door to me as vw/seat same in some ways, and a tech there told me he was aware of issues with the bonnet catch switch causing the same problem.

Basically oil level goes low, comes up on dash to fill up, you open bonnet (switch is stuck or broken) you top oil up to correct level but as the car hasnt seen the bonnet be open it doesnt turn the warning on dash off and reset. So i opened bonnet, traced switch wirring and it comes out to a connector above the o/s headlamp, i bridged a connection here incase the switch was done fore to make a circuit, closed bonnet, started car, job done.
