Replaced drivers side rear sensor Andy now the speedo is working. But still got the abs fault. Scanned today and no data coming from passengers side rear now so hopefully it will be the sensor on that side too. Just order another will update soon as I replace thanks

Morning thanks for the info if there is no change with the sensor ile look into the wireing do all sensor wires run up to the abs unit ? Anyone have a diagram of the abs unit plug ? If no joy looks like abs unit will have to get chanced. Will keep you posted thanks 

Hi thanks for the reply I’ve had it on the diagnostic yesterday for some live data when driving and I’m not getting nothing at all from both rear wheels. I’ve removed the sensor cleaned them and Checked the ring in the hub for damage all looks ok? I am waiting for the new sensor to arrive it should be here tomorrow. Just a question if the sensor has contenuaty could it still be faulty ? Thanks ile update tomorrow evening 

Hi yeah I just give it a try any way and I’ve tested both rear sensor sensor I’m getting cotenuaty from then both I’m getting around 1.031 but when I spin the wheel and check for ac voltage I’m getting nothing at all from both rear wheels. Do these sensors look ok to you as I carnt see much of the magnetic strip? Think I’m going to get 2 rear sensors this week. Thanks for reply 

Hi just a little update had the battery disconnected for 10/15 mins and had a little drive in it. Still the same with the abs light on. Asked around today been told to remove the rear 2 sensors and clean Also spray wd40 or simalar down the sensor hole an spin the wheels. Is this linked to Speedo and abs or both ? Should this be attempted.? Thanks  in reply 

Thanks for your reply ile disconnect the battery later and take it for a run. And post back this evening.Thanks 

Hi I’m new to posting, had my BMW 3-Series parked up now for a year as Ive had a company vehicle. Desided to get it back up and running again now but as soon as I start the car I’m getting abs light on dash without moving . Also my speedo is not responsive at all . Scanned it the other day and have these fault codes but will not clear them? Any advice would be great thank you. Please see photos
