My oil temp/level sensor went out about 5k miles ago which of course was shortly after my previous oil change. As the oil sensor is on the bottom of the oil pan, I was stuck with the error messages until the S4 was due for another oil changes. Today was the day I finally got to replace it. Out of all the things I fixed on this S4 the oil sensor was by far the easiest. Drain the oil, take the 3 bolts out holding the sensor into the oil pan, unplug the harness and work in reverse for the new sensor. Sadly I'm so used to something going wrong with "easy" repairs, it just feel odd when a repair actually goes to plan. I'm so glad to get rid of the stupid "Oil Sensor" warning light and beep.
As for the 034 Stainless Braided Brake Line Kit, it is currently standing by ready for install. I typically don't mess around with brakes and leave it to the professionals. Hopefully I'll have them installed and the fluid flushed before the 2018 Leavenworth Drive.
