After getting my first rrs earlier in year, the wife has been on to me for her xmas present......
Found a clean looking one earlier this week and got it home yesterday and stuck the computer on it for fault codes, and found only a couple which was an xmas present within itself. As I haven't found the spare time to put the dedication in that a lot of you guys have done I was hoping I could get some advice on fixes fro the following errors.

As alway any advice is really appreciated.

U0300 - Internal control module software incompatibility
B1b74 - Front foot-defrost mode stepper actuator
C1B07 - Directional Control Valve 2
B1D06 - Left turn signal circuit (noticed the indicator click is rapid)

Side note, when i turn the ignition on it makes a funky code that sounds something like an old Casio watch, indication of a mod ?
