If the car is tunned then most likelly the tunner has the engine light turning on to detect knock. Maybe

 

I didn't know anyone tuner using the "oil" light as the warning light.
And when you saw the flickinering did the RPM also drop abnormally low?

 

Perhaps he missread. The service engine light did not come on.

The car behaved normally, coming to a full stop. Idle was normal and oil was checked shortly after cooling off with no abnormality.

 

If you check the oil pan and see no metal shavings, then check the oil pressure sender/wirings.

 

Will do, thanks for the input. I am hoping it is the sender unit.

 

Reading apparently is fundamental. Carry on because I'm a dumb@$$

 

Maybe putting it in neutral took enough load off that the oil pump wasnt able to supply just enough pressure for that little bit? Has that light come on since?

 

my guess without reading everyone's post.... the ecu saw a drop in oil pressure for a split second below the threshold of showing the light, pressure raised over the threshold, light popped on for a split second = don't worry about it until it keeps happening.

 

The ECU does not control the oil light. There is simply a switch on the engine held open by oil pressure.

1. After a 120 mph run the oil will be hot and thin.
2. On coast down the ECU will shut off the fuel injectors.
3. Dump the transmission into neutral and the idle maybe goes a little unsteady. This could be due to the tune or maybe hot fuel.
4. The IX cars are known for weak oil switches.

Put it all together and you have the light flash on. I suggest putting in a new oil switch and keeping it in gear as you cool down.

 

Has not come on since and the car behaved normally on the drive home.

 

Thank you, I also think it was a scenario like this, since the light never came back on and the car drives normally.

 

Thank you for your advice & input. Going neutral is a bad habit of mine, hopefully I can eliminate it.
The plan for oil switch replacement is already underway

 

Maybe it isn't your case, but sometimes when you start to see this light, you'll see it more and more often until you get it regularly, and you'll soon realize that piston tolerances are starting to get bigger. A thicker grade and better oil will help.



....And I don't see where is the problem putting the car in neutral at that speed? I'd be curious to get some explanation on that one.

 

if the engine speed drops real low it will come on... for example, if you almost stall the car (drop below 500rpm) it will pop on for a split second.

 

Which track?
