mercedes vito speedo troubles

[marty35]

hi dk like above I have a 2004 vito and when I drive I drive it the speedo works ok for mins then abs comes on and speedo stops working ... i read dtcs with autocom and get p549e incorrect rotor at one of the wheels , I know the speedo works off the n/side wheel so I checked the wiring back to the abs pump and it checked ok so I changed the abs sensor and wheel bearing on the n/s front still the same , but on live data while driving the n/s speed is double what the other 3 wheels are, am looking at an abs pump problem .... thanks in advance dk ...
