Auxiliary Heater and Rear Left & Right Side Light

[jdstrickland]

I bought a BMW Scanner, and my car has two errors that I do not understand.

Heater and Automatic Conditioner Control
This section has an error for the Auxiliary Water Pump. What is this? I replaced the thermostat last weekend, should I have replaced the water pump also? I've never had an aux. water pump before. Whatever it means, it's an active fault that does not clear.


Light Check Module
I have two errors here, Rear Left Side Light, and Rear Right Side Light. The lights are all on. The top light is the turn indicator, then the tail lamp, then the tail/brake lamp (dual filament). The OBC is not telling me of a lamp fault. Turns out that these messages have been turned off in the BC.

I've played with this long enough that my battery is dead...
