I need to replace the oil level sensor on my '06 C280 4matic and cannot locate it. I read somewhere it is at the bottom of the oil pan toward the steering rack coupling area. We - 2 separate sets of eyes -- could not find it. Guess I need a diagram as t where it may be. If someone has one, or can describe where it the sensor may be I would greatly appreciate it. Thanks in advance for your assistance.
