Hello All,

I'm working on my car and I'm getting code P15DD, for my rear right speed/abs sensor performance/range. Upon using an autel, I found that all speed sensors get a good live reading and all the output speeds match. However, the code is still present, on autel it says, "increment wheel pulse." Now I assumed it was a sensor and purchased an OEM one from BMW and also verified the part number with them. The sensor didn't change anything, now there is rust and buildup inside the socket where the sensor sits, I'm unsure if that might be what's causing it and what can I do as a resolution. I don't think it's a bearing or hub as the wheel doesn't wobble or make any noises and the car drives fine. I also had this verified with a mechanic that the wheel bearing is okay. This leaves me with just the rust in between the sensor and the ring, how can I clean this rust as it's not in an area where anything at all will fit, maybe a very skinny flathead and some spray with an extended hose can fit. I'm confused if it can be anything else, it also is 100% not wiring/module related either.

ANY HELP WOULD BE APPRECIATED

Thank You
