About a month ago when the car was hot after about thirty minutes of normal driving,while idling oil pressure was about 1,2 to 1,3bar...Two weeks earlier the pressure dropped to 0,7-0,8bar...since then everytime the car was hot and idling oil pressure was well below 1bar somewhere between 0,5 and 0,7bar...When I revved the car it stayed at 3,5bar...that worried me for an oil pump failure...Also i noticed some strange surges on readings...(deviation of -+0,5bar at stable idle)So i decided to change the oil pressure sensor...It was a little difficult,airbox,Ypipe,throttle body and blow off valves needed removal and it took me about 3 hours to finish the job...When i started the car and let it warm up...Everything was ok...now the oil pressure stays to 1,5bar at idle even if the car has raced before...and it stays over 4bar above 2500rpm...The reading is stable without any surges...

 

Good job fixing this yourself.

 

Hi I don't flash porsches like you guys but today i noticed a problem on my car, when it idles still the oil pressure gains and drops constantly as if it was revd of some sort. It almost stalled while it driven home. Does anyone have an idea whats wrong?

 

you should start your own thread...and get the codes read.

 

If there are no codes 99% you need to change oil pressure sender unit...as i described above...

 

I just got a 996TT and at idle oil pressure is around 1~2 and 3~4 under light load and around 5 under heavy load, is this normal?

And sometimes the oil pressure reading gets the shacks :-)

Thanks,

Az
