S2 stopped on highway - low oil pressure -help needed

[EvenM]

Have you pulled the fault code

Yes, but the fault come and go, so when I Pulled the codes, nothing showed, other than g62? Coolent sensor something, that I dont think have something to do with this

Can try again tomorrow

Now the car is shopping when get hot , aprox 15 min after startup. Can g40 cam sensor be the culprit ?

[Monkeymagic]

Could it not simply be that you have a ignition/sensor fault that has caused the engine to cut out, rather than an oil pressure issue. Once it has then the oil warning light will blink.

Not me personally, but I know of someone who lost oil presure, not enough to cause knocking but low enough to barely register on the gauge and the oil pressure relief valve had stuck or spring snapped (it was over 10 years ago now). He thought the worse regards oil pump but these don't tend to fail instantly. Suspect this especially if it was the gauge that dropped as engine cutout is normally activated from the pressure switch not the sender for the gauge, but will check this as its been a while and lots of water passed under the bridge..

Thanks for the information Please update me if you find out more

thanks, this is a strange one, but hopefully I will figure out whats causing this

So Always something after winter storage




oh yes indeed...or just a few weeks of inactivity- had a bit of drama getting mine to fire up again this week...thankfully it did eventually.
Good luck with finding your issue

Oh, good to hear it fired up eventually, what was wrong ?

Any suggestion to what kind of electronic fault that can stop the car while running when the oil pressure light comes on?

[EvenM]

I know this for a fact

Not good

[Rikki Kitto]

Nope! You can run the engine without oil pressure until destruction!!
I think is something electric.

what fault codes did you see ?

Pulled the codes today, none regarding this issue.

After that I turned the engine, it started, and the oil pressure boosted right up to 5 bar on the guage in the car. So everything seems normal again, weird...

So I think it have to be a electronic fault.. Always something after winter storage

[Pirvu Eugen]

Im sure the ECU looks for initial oil pressure to give permissive to start engine or am I dreaming?
