2004 VW Touareg, Low oil pressure stop engine now light

The Low oil pressure stop engine now light flashes on briefly as we slow down to 60Kh.  The oil is up and clean, no burning.  The engine is not overheating and there is no engine noise to indicate damage.  The dealer changed the oil pump claiming that it would solve the problem.  It didn't!  We have changed the oil sensors and still no improvement.  The dealer now wants to redo the bearings on the engine at our cost of course.  They claim it might works.  The dealer has put this car on their computer and it comes up with no pressure problems and yet they want to charge us $3000.00 after we have paid $2000.00 for the oil pump.  Help,  does anyone out there know whats going on.  I have had numerous other problems to many to list.  They still to continue to haunt me even after the issues have been addressed. Just as a note we continue to drive this SUV even with this problem and it drives and behaves as it should.  Lots of power and acceleration.

    Thanks. The service dept. at VW has checked the vehicle with a mechanical oil pressure gauge and then drove the vehicle. They claim that it took alot of tries before it showed up. They claimed that when it did manifest itself it was low pressure at about 60kmh.

    Which I have stated to them. It doesn't show itself all the time. So it is difficult. Is it not true that if the bearings are gone or need redoing, should this problem exist all the time, not just now and again. Should the engine have some other indication of this problem by now? The engine continues to sound O'K.

    Any other solutions or advise.

Sounds like and electrical problem in the oil pressure sensor circuit. I wouldn't rebuild the engine just yet. Hook up a mechanical oil pressure gauge and drive the vehicle with the gauge on it so you know exactly what the oil pressure is.

    If it had bad main or rod bearings the oil pressure would be low at idle. And your does it under load. I think your suv has plugged oil drain back holes in the cylinder heads. The oil is pooling in the valve covers and not returning to the oil pan fast enough for the oil pump and the oil pump is sucking air. You should run this by the tech that is working on your problem. He will likey agree with me and pull the valve covers off the engine and check for this problem. Let me know if this works. Hope I helped. Good Luck.

Oil pressure warning light flashes on & off when I start to slow down to a stop????

it sounds like the oil sending unit which is an inexpensive part and simple to replace it should be located between radiator and engine on the side of the oil pan

Code p0011 bank 1 intake timing position is over advance,oil light flashes/comes on when i take off/slow down or at complete stops

The computer controls the cam timing by using a solenoid valve inside the engine. The valve works by oil pressure.
The code means the computer can not control the valve timing. Usually the valve is faulty or there is a problem with oil pressure.
Since you say the oil pressure light is coming on, I would expect to find a problem with the oil pump or excessive dirt in the engine.
If the oil pressure switch is good, it will turn the light on when the oil pressure drops below 5 psi. And if it is that low, I doubt oil is reaching the valves.

After driving my car 2006 chevy impala for about 20 miles the dashboard warning light oil pressure low stop engine and the oil warning light appears, but if step on break or slow down it goes out..wha

Verify that the engine has the proper amount of oil. The inertia from accelerating may be moving the oil in the oil pan away from the sensor and causing it to send a signal, then when you slow the oil levels out and the sensor go's off. I've had this happen alot with a taurus that I owned. The simple solution was to top off the oil to the correct level and the sensor did not come on again (until it ran low again, had a leaky oil plug on oil pan).

Why is my oil light dinging while driving. I just changed my oil, and level is fine. But the oil light is flashing. Mostly when I come to a stop or slow down.

Hi Martha,

The oil light can only come on for two possible reasons:

1. Your oil pressure switch is defective and is "lying" about how much oil pressure you have. In this case, replacing the oil pressure switch will fix your problem. (This needs to be checked FIRST)

2. You actually have low oil pressure. The main reasons for low oil pressure are worn out engine bearings (making it time for an engine replacement or overhaul) and debris getting stuck in the oil pick-up tube screen. I have fixed many of these by removing the oil pan and cleaning the debris out of the oil pan and oil pickup tube. Many times, sloppy repair work on various parts of the engine will result in pieces of gasket material and chunks of silicone that get trapped in the pick-up tube and cause the symptoms you are describing. The way to go about this is to remove the oil pan and inspect the contents to see what is going on. If there are a lot of metal particles, then the engine bearings are damaged. If there is just a lot of junk and debris (with no metal particles) like described above, simply cleaning it out will likely solve your problem.

The oil light starts to flash when stopped.

Your oil pressure naturaly drops when the engine is reving slow ( stoped ) , the oil pressure sender unit sends power to the oil light when the pressure drops below a preset value.
EITHER the oil pressure sender unit is faulty ( a common occurance ) , or you actualy have unusualy low oil pressure which could be caused by several different problems.
I would suggest replacing the sensor , it it still happens , you have a more serious problem.

The Warning Light Comes on "Stop Engine Low Oil Pressure" what does this mean

car needs oil pressure or bearings will wear out in short time. Do not drive or start engine with this light on. Might only be pressure sending unit. Can replace sending unit and start briefly to see if problem resolves. If light still stays on, shut off engine and have oil pump replaced.

Check oil light comes on at a stop and while idling

this is a light that indicates low oil pressure or low level, 1st check the oil level in the engine when it is hot, if that is ok you will need to have the oil oil pressure tested with a specail mechanical test gauge, don't wait on this, low engine oil pressure or level can quickly lead to engine failure, have a shop check this ASAP if level is ok and light still comes on.

Low oil pressure

Sounds like you have an internal engine problem. the only way to be sure is to check the oil pressure with an external gauge.

Oil Indicator Flashes

The light doesn't indicate oil level, it indicates oil pressure. It could be a faulty sending unit, a plugged oil pickup (way down inside the oil pan), or the engine could just be worn. Also, if it's idling too slow it could be coming on. Time to go see your favorite technician. Good luck.
