2010 S model 1.2TSI.  Switch on ignition (but not start engine) Warning lights show and some go out as normal till engine started then all off.  But I have noticed that on switch on but not start up the oil-can light comes on red for about 3 seconds then changes to yellow and blinks 4 times then goes off and stays off when I start engine.  I would have thought light should have stayed on till engine started??

 Sorry but have just noticed this and can't remember what has previously happened.....am I just worrying needlessly and the light should go off and when engine starts the computer recognises that and an oil pressure fault would be shown........or is there a defective pressure sensor?

Where is the sensor?

I hate these modern vehicle controls systems...so unreliable.

Sounds like a check of the dash lights and warnings.

The Yellow or Red Oil can does not stay on until the engine / sensors know the oil level or oil pressure is correct. 

 

If you ever get a Low oil warning message or Low Oil light when driving because there is low oil and you stop and open the bonnet for 30 seconds and do not top up the oil or even dip the oil the Warning then goes out for 100 km / 62 miles.  Simply not clever 

 

PS.

Is your oil being kept topped up to the proper quantity.

So up towards the A area of the cross hatch and dipped when cold before starting to be sure there is oil, but the proper check done at Normal Operating temp so after the oil has got to 90*oC.  Checked hot, not 'warm like a Skoda manual might say.

I would check for stored fault codes with an OBDII reader.

There's no pressure sensor, but simply a pressure switch (open circuit when pressure is below threshold, short to ground when above).  Test the warning system by unplugging the single wire connection and driving the car, expect red warning light above 1500rpm if not before.

Thank you for the rapid detailed replies.  I am now de-stressed 😊

The Yeti is kept looked at and periodic simple checks like oil/water/other fluids checked.  End March was its last oil change/full service at a reliable local garage (while I got on with complete nut/bolt rebuild of 1936 car.) Note  - a garage that really does check and actually does service items rather than just see if it  has a fault.....Quote from a large main dealer after callipers had to be replaced and rears ditto due to seizure having not been greased in-spite of regular service by Skoda franchised garages......"Oh we only inspect and only take action if we see a fault" !!!!!!  I have the satisfaction of knowing that my local actually does re-grease the sliding parts of callipers as well as actually doing all the other SERVICE requirements.

I am more used to dealing with vintage (up to 1930), post vintage thorough breads (PVT up to 1939) and classic - currently very modern 1980 (proper classic not just old).  An oil pressure gauge tells you exactly what is going on and any variance from what is expected can be usually fairly quickly diagnosed to a fault.

 

Modern vehicles seem to be aimed at trying to electronicaly cover all posibilities  and even cover what some rather silly people will do or not do.    Someone will say a lot of it is to save manufacturing cost.......great but. when even a small fault occurs the average person can be landed with a rather large bill negating the saving in purchase........together with depreciation you pay more in the end.

Having spent a professional career working with high end defence equipment,  I can say that automatic fault indicating systems are somewhat limited and sometimes even indicate false problems.

Sorry for bit of rant but we need to come back to reality.......I dread the thought of "driverless" cars that need no driver input.
