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.
