Fault codes help needed

[rourkemason]

Checking the OBDII had a list of error codes, few that stood out were:
P26F800 - Coolant pump C stuck
U042800 - Invalid data received from steering angle sensor module
U101100 - supply voltage too low
C10D700 - comfort restriction
B12ECF2 - LED module left for DRL and parking lamp Supply, open circuit/ short circuit to B+
I appreciate it’s a lot but any help would be great as i’m new to VAG
