Hei guys. I have a VW golf (2010). Just add the engine oil. And the following day when I was about to start the car I foud the engine oil light flahsed(yellow light) for 6 times. After that it went away. Now every time i put the key and turn on the power the same thing happens. Seems on the manuel it doesn't explain this. Is it a big problem. Any one knows about it? Thanks a lot

Flashing yellow light appears to be oil pressure sensor fault.

Better not drive the car till you get that checked out. Sensors are usually very easy to change and should cost less than 15 Euro or so.

No its level warning sensor warning. Oil pressure warning is pretty much always red and requires immediate stopping because after that baby is lit for a reason the engine typically has minutes if not mere seconds to live if not switched off. Camshafts and turbo charger for starters not to mention cylinder linings aren't exactly cool on missing out on lubrication which is the upshot of loss of oil pressure.

Oh the warning light in your case apparently means the car does not get oil level reading before turning the engine when starting, I would not be overly concerned as long as you know there is sufficient oil. The sensor really only works when the engine is not running.

That+op's first post indicating that car got more oil, not oil change, makes me think about possibility of too much oil.

I did a little browsing of VW forums after seeing this. I didn't pay to download the owner's manual and anyway you're sure it doesn't explain it.

Everybody seems to say that VW has never had an oil level sensor. Instead it is (as you'd expect) the oil pressure sensor and quite a few people reported having full oil but next to zero actual measured oil pressure due to a variety of internal engine faults. It seems to be a VW weakness. Obviously that can quickly become catastrophic.

As much of a PITA and expense as it is, I would take no chances until you have a definitive answer from a dealer or fully qualified mechanic who knows this vehicle. You may find someone who can measure the actual oil pressure on-site with simple portable equipment.

OTOH are you sure it isn't just an oil-change reminder counter? Turning itself off sort of suggests it might be. Have you owned the car through other oil changes? In some cars it's as simple as holding down the mileage reset button for ten seconds while you turn on the engine.

Do you see this symbol lit up in red before the car is started?

Does it go out when the car is started?

Does your flashing yellow light look like this?

Flashing indicates a sensor problem for the oil level sensor which is a different sensor for the oil pressure light. Your manual might be wrong. Either way low oil pressure should be a red danger light rather than a yellow warning light

The fault could be caused by the bonnet opening micro switch being dirty or broken! - Which might account for why this problem arose after the bonnet was lifted for the oil change.

Indeed, oddly enough the oil level warning warning is reset or cleared only after the car detects car's bonnet being been opened and closed for topping up the engine oil, however if the issue was caused by the bonnet switch the warning light should burn solid, not flash as in indication for faulty level sensor.

It is the second picture but without the words, flash 6 times the it goes away.
