Camshaft Position Sensors (CPS) part number
Hey I just bought a 2015 S550 4MATIC with 63,000 miles. I heard about the notorious CPS Problem leaking oil in the engine harness. I haven’t checked to see if it was leaking but I was going to replace them and put the sacrificial harnesses on them. I heard that 2769051000 was the new ones that claim they don’t leak 🤔. I also see ones that are 2769051100. So my question is are the 1000 or 1100 better? Some sites claim the 1100 works with this engine but I’m skeptical. What do you all think? I have the M278 engine.

My recommendation, If they aren't causing issues just clean them with electronics cleaner spray and install the pigtails. Check both ends of the pigtails at every oil change, clean with electronics spray, and repeat in 5,000 miles. Wont hurt to swap them out, but I'm not confident the issue was actually resolved.
