W213 oil pressure warning




Been ongoing for a couple of years now since I bought it - pressure sensor replaced with no change, became more and more frequent and MB did a re-program of some module and it went away for 6 months or so, and now comes on but very rarely, maybe once every few months. I've chosen just to live with it as I figured it was a wiring fault like a loom breaking down, but knowing others have the same problem means it's definitely a software problem somewhere.

Not a W213 specific thing, the cars have been doing this for a while, especially if youre driving downhill it seems.
Hell my S550 4.7L did that when I'm going downhill. I don't want to assume we have the same problem, but I replaced the pressure switch with the next oil change and so far so good.
