     Hey, I am new to this site and have been searching but didn't find much on oil level sensors. I have just got a 2011 cayenne s 958 4.8l and I am new to Porsche, I have worked on many VW's and Audi's and now it time for me to take the Porsche challenge. When I bought it I was told the oil level sensor was replaced and worked for a couple of months then stopped again ("Failure Oil Level Measurement" light up on dash after running engine a short time). When the previous owner took it back the mechanic told him the sensor was good and that it must be a bad ground somewhere but didn't fix it. I was going to replace the sensor again with the Porsche sensor because I thought that they used an aftermarket one that are known to go bad. It looks like they did use an official porsche sensor but I was not able to remove it because of the engine carrier in the way, it turned out to be a much more time consuming job the I was expecting ( 10 minute job turned out to be hours)  so I haven't replaced it yet.

   I have two questions:

is there a trick to removing the sensor and

which connector in the upper engine compartment is for the sensor so I can test the wiring down to the sensor.

   I have an Icarsoft because I wasn't able to access the controllers without security codes with a Vag-con. Icarsoft reads 4.72" of oil even I unplug the sensor or oil change with 9 quarts added then 1 more added.

   Any help would be much appreciated, this is starting to drive me crazy.

Can’t get pic until I get back under there, when I attempt to do it. 

It is the same or similar sensor but is mounted in the back upper oil pan and the engine carrier crosses behind the lower pan a couple of inches below the sensor. My thought was to unbolt the right side engine mount and raise the engine an inch or so to make room to get the sensor past the space between the lower pan and engine carrier.  If that doesn’t work the lower frame that supports the front end has to be dropped because the bolts that go through that then go through the engine carrier to the chassis. After you remove the lower frame you can disconnect both motor mounts and remove the engine carrier. It seems like a ridiculous amount of work to have to do to change the sensor that in  most cars would only take five minutes. That is why I was hoping somebody with more experience would have a better idea of how to do it without all that work.

Unreal! I have looked at the part and assumed it was right at the bottom of the oil pan.


So I searched and read through a few forum threads and it seems to be a difficult job after reading a couple if them...


Maybe read through these





I will check alldata to see if they have a solution. If so the subscription is very affordable.

I saw a post somewhere that claimed one can raise the engine with a jack under the oil pan without unbolting the mounts.  Supposedly you can raise it just enough to be able to get the sensor out but I don’t feel comfortable putting a jack on the oil pan  and I’m not familiar with the mounts to know if they move that much without breaking.

Well don’t take my non-explicit response wrong but since their service is subscription based and copyright I wont repeat their process however it clearly tells you how to do this job.


Their pricing is also very reasonable if you buy the alldata diy version specifically for your year make and model.


I think I paid approximately $40 for 5 years of access...
