How acurate is the oil guage method ?

[c240yaz]

Friday night, driving from Preston to Mull of Kintyre. Oil warning light comes on M74, Hamilton area, continue to drive for 1 hour plus.

Stopped at Gourock before joning the ferry. Done the electronic check. Dial says "Add 2ltrs". I had a one ltr bottle in the boot. Added. Waited 5 mins. Dash board new reading says "oil plenty". Could the sensor be faulty ? and where exactly is it situated in the block ?

I wish I could dip manually as this electronic method is for the birds.

Tomorrow, I will do an oil change anyway. 6k since last change. Chevron 5-40 fully syn, and Euro filter Hengst.

hence why they have gone back to the dipstick on new cars...

On the newer W203's you can see the sump content in litres in a hidden menu, and there was a post the other day about doing it on older models, but not sure if it works on yours.

Here's the thread I was thinking of:
