Oil Level Sensor
Hi Guys, I got 27C3 Thermal oil-level sensor = P1128 error code, so I believe the oil level sensor is out as I did not got any warning and on oil drain got only 4L out of my 6.5L capacity M54.
Now, while attempting to replace the oil level sensor, should I also replace the oil pressure switch + Oil temprature sensor? Do these two sensors go bad?

The temp sensor/pressure switch rarely goes bad but for $10-$30 why not. It is really up to you. Being that thy have not failed you do not need to change them.
