Service engine, ABS, DTC

A few days ago I drove my 2011 135i convertible (manual) through a rainstorm, parked it in a valet garage, and the next day when I picked it up, my dashboard lit up like a Christmas tree.

The first light to appear was ABS, followed shortly after by Service Engine Soon, and what looks like the traction control icon. The car starts fine, brakes fine, and runs completely fine. It didn't go into limp mode, oil temperature has been normal, but after multiple restarts and many miles I still have all the lights on.

The codes are:
5DB6- WHEEL SPEED SENSOR: DIRECTION OF ROTATION, REAR LEFT
32D3- VEHICLE SPEED, WHEEL SPEED SENSOR REAR/LEFT, ELECTRICAL MALFUNCTION
32C9- ROUGH ROAD DETECTION: NO WHEEL SPEED SIGNAL RECEIVED
A559- INSTRUMENT CLUSTER: POWER SUPPLY HAS BEEN SWITCHED OFF (CLOSED-CIRCUIT CURRENT CUTOFF RELAY)
D690: RING BREAK DIAGNOSIS HAS BEEN CARRIED OUT
E18D: WAKE UP NETWORK UNSUCCESSFUL
