Hello, the sending unit is to the right of the oil filter adapter, it is behind the engine mount bracket, it is hard to see and difficult to access. You will need deep oil pressure sending unit socket. It has a electrical connector.

My 2007 Buick 3.9 liter oil light comes on and off. ..stays on for a while then goes back out. Checked the oil level all good. I did recently change the oil to GTX 5w30 extended milage oil. Any idea

The oil light comes on when the oil pressure sensor detects low oil pressure. The amount of oil has little to with it, although very low oil levels can cause loss of oil pressure. The best thing to do is to have the engine's oil pressure checked with a mechanical oil pressure gauge to ensure that the oil pressure is sufficient at all operating speed and temperatures. If the oil light is still flashing on and off and there is no indication of low oil pressure by the gauge, then replacement of the oil pressure sensor is recommended.

What can be the problem the oil light stays on on the dashboard but the oil level is ok (endura de)

The oil light refers to oil PRESSURE, not oil level. That said, if the oil pressure is low enough to set the oil light, then you should be hearing rattling noises coming from the engine when it is running. That is not to say that you may not still have a problem. The oil light is nothing to take lightly. If there is an oil pressure problem, engine damage can occur quickly. Check the wiring connection to the oil pressure sending unit. If you suspect that the problem is not really low oil pressure, then change the pressure sensor. It is relatively cheap and the easiest way to verify whether there is a real problem. If the light remains on after the sensor is replaced, have the oil pressure tested with a mechanical gauge to verify that it is low. If it is low, you either have a very worn out engine, or a malfunctioning oil pump system.

I have a vw caddy van 2.0 litre sdi,an recently the orange oil low level warning light has come on,the oil level is fine,I have replaced the oil sensor switch bolted to the engine an still the light stays...

I would recommend that you change the oil sending unit. When the oil sending unit is faulty, or simply clogs up, it will trigger the oil light because the engine is not registering enough oil pressure.
I hope that you have found this information to be useful, and if I can be of any further assistance, please let me know. Thank you for using fixya!

Oil light is on although oil level is fine.

Sounds like this may an issue with the oil pressure sensor.

Oil lights stays on

If the engine is not making any noise then it is likely not a real oil pressure problem. Just to make sure have the pressure checked by a shop with a mechanical test gauge and if found to be inspect replace the sending unit and that should in most cases cure the problem. I assume this is a pressure indicator.

No oil presser. engiene oil light registers no oil presser

Not good. First thing to do is check the oil level and fill it to the mark on the dipstick if it's low.

There is always the possibility that the oil pressure sending unit is giving a false reading. However, if the reading is correct, you have a major problem.

I wouldn't drive the car. You could quickly do major damage to the engine. Have it towed to a service facility.

Oil light on when hard braking or turning.

hi there this sounds to me like your oil level indicator is saying the oil is low, if this is not the case you need an oil change.
or to stop hard turns and hard braking lol.
