1- do you have aftermarket audio or alarm installed recently- if yes, that is likely the phantom drain.
2- if this just developed, does the fuel pump remain on? You can hear it running if kneel down by the gas tank. If so- relay may have fused contacts- in which case replace relay. Alternately the oil pressure switch may be stuck closed. in which case- replace the oil pressure switch- it is not the same one that controls the oil pressure gaauge or light- those are in a different location.
Hi.This will indicate that there may be some sludge build up in the block, or the oil pressure switch is damaged. The more serious issue will be a failing oil pump. To isolate the issue, simply, have a oil pressure test ran on this engine. If the test indicates that the true oil pressure is optimal at idle, kindly replace the oil pressure switch. Now, if the test proves that the pressure is indeed lower than factory specifications, this will confirm that the pump is damaged. Have the pump, and oil pump screen replaced, in this case.
NOTE_ I would, also, recommend to have the engine flushed asap.
The only way to tell for sure is to temporarily install a mechanical pressure gauge and read the actual pressure. That will determine the next course of action--replace the pressure sensor/switch, or recommend remedial action within the engine itself (worn bearings, worn oil pump, or plugged intake screen). Hope this helps!
Probably the oil pressure relay. Go under dash when its buzzing and locate it . Turn car off and remove it.
If its the oil pressure relay have oil pressure check by a repair shop ASAP.
It means the sensor that detects your oil pressure has seen a situation where the oil pressure is too low and engine damage will result. Could be just a bad sensor, but better have it checked with a mechanical gauge to see exactly what the pressure is.
Check the oil level is not low, and the oil in use is of suitable grade & quality.
If it only comes on at idle, you may have a faulty oil pressure alarm sensor switch.
Either replace it, or preferably, get the engine oil pressure tested using an independant oil pressure gauge.
If it is verified that the oil pressure is indeed low, you may have to look further for other engine problems, such as worn camshaft/crankshaft bearings.
Could be a few things, I assume you've checked the oil level. You could have a worn engine and therefore low oil pressure, could need a new oil pump. you can connect a mechanical oil guage to check whether it is a problem with your guage
HEY MAN MY FRIEND HAD A AME PROBLEM ON HIS CITI GOLF THE OIL LIGHT GOESON WHEN THE CAR IS COOL ONCE HE DRIVES IT DISAPEAR THE PROBLEM WAS THE OIL PUMP INTO THE SUMP MAKE SURE U CHANGE IT YOUR OIL FILTER WILL BLUST ONE DAY ESPACIAL IN WINTER WHEN YOUR CAR IS COLD
cuircut dosent work like that there is no fuse
ground both wires one at switch at filter housing the other at the side of cylinderhead. light should flash but not buzz.if so replace swiches.
with wies grounded if buzzer still goes off you have a wiring prob or the instrument cluster itself or low. check oil pressure ofcourse?
