I had similar symptoms and replacing the bad sensor fixed it

IthacaMD - as
andy_06xi noted, start with a speed sensor sensor. You can get ATE (OE supplier for this part) - it is super cheap and identical to one installed at the factory. It should take you 30min to replace the sensor, out of which 15 min is removing and putting back on rear right wheel
The speed sensor triggers all above lights as its data used for ABS, traction control (e.g. your 4x4 light)
Once sensor is replaced, lights will go off.
I had exact same experience last year on my E91.
