ML 164 FRONT ABS SENSORS

[nick325tds]

Hi

has any one ever come across front ABS sensors giving different reading o/s to n/s

brand new Mercedes abs sensors 2 new Mercedes front wheel bearings......in the right way ! 2 new front Tyres original wheels

abs light flashers at 62 mph ....snap on ultra no abs fault codes .....live data is showing 10 rpm difference ...hence light is coming on !

any one got any thoughts ,,,,,please

thanks
Nick

Corrosion in the terminals? So high resistance.
Air gap between the sensor and reluctor ring on the bearing.
Faulty sensor or bearing?
Can the sensors be swapped side to side just to see if the fault location changes?
