4 yellow lights
- Thread starter Kevrev
- Start date
Pull all the wheel speed sensors from the back of each hub and give them a good clean. Check the ABS reluctor rings also for muck/damage. I had the same lights 3 or 4 years ago and fitted new brake pressure sensors with no change. Then sent the ABS Pump to ECU Testing which came back as fine. Pulled and cleaned all the ABS sensors and bingo...all lights gone ! All clear since then

Only a few weeks ago I had the same issue after changing the front discs and calipers.
Mine was the left front ABS sensor. Cleaning didn't help. I think the transmitted shock from the hammer I used to shift the disc must have upset it.
It was a quick and easy swap.
A code reader will tell you more. For me it meant I knew exactly which one to change.

Not got a photo to hand, but on the front ones, there's a rectangular box on the inner edge of the wheel well, behind the strut. Follow the cable from that down to the hub. you'll find a sensor poked into the back of the hub assembly, held in by one bolt.AnilS said:

Hi mate - I'm in London and would lend if closer, but might be worth getting one. They are only £40 and well worth it (you can always sell if you move out of the BMW brand):

Quick update on mine. After trickle charging the battery, back to full strength, the lights warning lights were still active.
I went to my Indy today for a minor oil filter leak (new gasket fitted) and they ran a diagnostic check. It wasn't any sensor but the ABS Hydro pump. They had a tinker with it and the lights have gone. Ultimately, it may need a new pump but for now, all is well again.
