Got the dreaded abs/4x4/flat tire... Checked code and got 6d9b wheel sensor left supply.
Since im not home i could only take off the sensor, the "ring" looks fine, did find some metalrust in the hole i removed, saw one spot on the ring with clean metal, saw nothing on the senor and still protected by rubber, same with connections, looked clean.
Also checked with protool and left front gives no signal for wheel speed.
Weird is i drove several miles with it on, parked it for 2 days and then it was off for a few mile before coming on again.
Is there a way to test the sensor with protool/ista/ inpa or multimeter?
Aswell test for voltage from ecu to sensor?
Put positive lead on sensor connector while unplugged and negative lead on any ground. Turn wheel and you should get a voltage reading 190-1140mV. If not something is wrong inside and it's not the sensor. If you need a sensor get BMW or OEM only. Bosch is OEM
