Got this to resolve EBD,ABS,ESP fault. It did locate rear right axle sensor and L6/4 (right rear sensor) unreasonable. Fault Code 44D900. What kind of fault code is that? What happened to codes like P1234? Anyway, replaced sensor. Fault cleared and reset. Drove off and as soon as you reach 10mph warning lights back on. Now shows code 44D700 The signal of component L6/4 (Right rear axle sensor) is unreasonable. So what does that mean compared to first code?? Nothing online that I can find. I'm thinking sensor ring is the problem. At least the old codes are more specific. If I'm right this is a big problem. Cheers Jim
