electronic oil dipstick

[bovine]

Recently bought an '05 997 S. The electonic oil level indicator showed oil was below min. Added 0.25 litre oil. 5 mins later oil level reading is unchanged. Added another .25 litre. Leave 5 mins, let electonic dipstick do its thing. Now reads 2/3rd full. I figure the reading after first 0.25 litres must have been wrong. 4 days later after filling petrol electronic indicator auto measures oil, says its below min again. Measure again at home, still below min. Measured again 1st thing in the morning so fully cold/drained and still says below min. Can't see any obvious oil leaks. Oil pressure is fine, cold starts at 5, drops after warming. Can't find much info on electronic loil evel indicator problems. Any suggestions?

I find mine to be very-very accurate.

The most accurate reading will be the one first thing in the morning, not the one at the gas station.

Getting an oil change should be factored into your "purchase price" so go get an oil change, make sure they drian the warm/hot oil for a minimum of 20 minutes, and then refill with the correct Porsche approved oil and quantity. Then you will have a basis point, and know that the oil is proper and clean.

Thanks White. I've got a 250 mile drive to make tmrw so will have to wait till I return. Afraid of adding much more oil in case of over filling. I might try and get someone to have a look at it before I go.

Make sure the ground is very level too.

Re-measured again in a flat multistory car park. It needed to add another half litre to get to 1/3 full. I think the 2/3 full measurement must have been wrong. Will only measure where I know ground is definitely level from now on.

Also keep in mind that the difference between the min and max mark is about 1.2 liters, making each segment equal to approx 0.4 liters.

I've found out parking on left side of my road, (car tilts slightly to the left) gives an approx 800ml (2 segments) higher reading than parking opposite on the right side of the road (car tilts slightly to the right). Just street curvature for water drainage.
