Oil Warning

[S2_Dave]

Yesterday my oil warning light came on out of the blue aftere driving for a couple of hours. I continued on my journey, as I didn't have far to go. Today when I came to use it again, I checked the oil level and whilst in the car pressure seems OK (4.5+bar and 2bar at idle) when up to temperature. On my way home I noticed that the warning only came on when I hit 3k rpm. I tested this several times and it's like clockwork. I've searched the forum and discovered that the warning cannot be due to oil level, as there's no sensor for this, so could this be my oil pump on its way out? I've read that there's two pressure sensors here, but it says that the difference is 2k rpm. Could this be the same thing, but mine is set to 3k rpm somehow? I'm hoping it's a sensor that's the problem and not something more serious like the head gasket!

It's going to MRC next Friday, so they can sort out the problem long term, but will I do any damage if I continue to use it until then?

probably a faulty switch

Is there any way I can test if it's a faulty switch?

hi

you´ve got 2 sensors.

one is bigger and has 2 contacts. in this sensor you got a sensor (contact "G") and a switch (contact "WK").

the sensor is for the oil-pressure instrument in the middle and works from 0-5bar.

the switch works until 0,3bar.

the other switch is below the bigger one mounted and smaller. this is the 1,8bar switch. this switch gives at 2000rpm a signal to the autocheck/oil warning light if the oilpressure is higher than 1,8bar.

this one should be the problem. if you want to check this you´ve got to put the cable of this switch to the ground. then there should be no more oil warning light. if this comes true you´ve got to change this switch.

for the moment you can always look at the oil-pressure instrument. if there seems everything alright you can ignore the oil-warning light. but you have to be carefully with driving.

good luck

Thanks for the info. I'll use it as little as possible and drive tentatively until next Friday.
