porsche 996 onboard computer oil reading

[barriejames]

Hi All

I was playing around with my onboard computer on the dash and when I start the car the oli diagnoistic takes about five seconds which is fine. However if I switch off a few minutes later and start again it wants 10 minutes to do the same check?? any one else had this and is it ok to hit the cancel lever? do I even need the diagnoistic display if I check the dipstick weekly?The oil level is fine also?

Thanks

Wet sump, oil is in engine.

Best to do when car hasn't been driven for a few hours. Check dip stick for 100% accuracy.

So ok to ignore the 10 minute countdown and pull to lever to cancel? and just drive on?

Cheers

The car wants the oil to have time to drain into the sump before it is measured and this happens much faster when the oil is warm - a few seconds is enough when fully warm, 55 minutes or more is indicated if it's just been started from cold then switched off.

Thanks puts my mind at rest as drove it 350 miles yesterday after picking it up and naturally you never know quite what you purchased, even after checks but the oil level on the dipstick remained same so not an oil burner at least!! my old 996 year 1999 never had this function.

It did, it automatically starts checking everytime you turn the ignition on before you start it. Maybe you just turned the key all the way to start it.

Aha, saved me the trouble of asking 'why' as well! Normall get a 7 minute wait time f say I switch off and then on staright away in a petrol station or shifting cars round. Always happy to wait the 5 secs, but not waiting 7 minutes

Does the oil pump get primed or anything during to the 5 secs, or just the car self-checking before you drive away?
