It all started two weeks ago. in this order:

20 days ago: One angel eye not working on the Xenon beam
10 days ago: Second angel eye not working on the H7 High beam + H7 High beam not working
5 days ago: ABS + Emergency Break + Warning lights turned on
2 days ago: Speedometer not working
1 day ago: fuel efficiency gauge not working (I am not sure if we went out at the same time with the speedometer, I can't remember)

I've read a bit about the ABS senson on the driver's rear wheel. Is that all of it? My gut tells me it is something more.

Thank you for any input in advance!

Start by getting the ABS module codes read to see what clues there are. You will need BMW specific scanner to do the job.

I would do the following:
- measure the battery voltage with a multimeter, both with key out and with engine running, they should be at least 12.4V and 13.5V respectively
- scan the ABS module trouble codes with BMW Scanner 1.4, since the last three things failing for you are vehicle speed sensor related
- visually inspect all the electrical wiring and connectors under the hood for obvious damage
- look at the angle eyes last, since they***8217;re not critical

With BMW Scanner 1.4 you***8217;ll be able to scan the trouble codes and see live data for all the control modules, including ABS, IKE (instrument cluster), DME (engine control), and the rest.

Set up BMW Scanner 1.4 on your Windows laptop. The cable is $20 and the software is free, scroll down for the download link.
