Check Engine Light

So a weird thing happened today, I was driving then all of a sudden my car jerked a couple of times and the check engine light came on. I hooked my scanner up to it and it showed "P0339 Crankshaft Position Sensor A Circuit Intermittent." FYI, my vehicle is a 2015 S550 with just under 50k miles on it. I'm still under warranty (CPO), so no issues there, just wanted to know if anyone else have experienced this. I'm just waiting for my dealership to call me back so I can get my car in the shop.....

Most likely oil got into it causing the cam sensor malfunction. Had that happens to my E63s and dealer replaced it under warranty as well.

I don't know how on earth the oil got into that sensor causing that issue but good to see it was fixed for good without having more problems
