Hey guys,

Just got an 07 335i w/ 325k on the current odo. Catch is...the odo is not turning as you drive. I picked it up for nothing and the car is immaculate w/ 1 owner. The cluster works, but the speedo, MPG, and odometer does not tick up. Is this a rear wheel speed sensor? I thought if it was the ABS lights would kick on too which they are not. The RPM, Temp, Gas, clock, even miles to empty works...but speedometer sets at zero and odo doesn’t move, trip doesn’t work either. Ideas?
