Hello, does anyone have any experience with any of these trouble codes and/or symptoms? - and if so can you share how to go about resolving them? Thank you

Fault codes in posted photos -:


Symptoms are

1. Intermitted keyfob operation/ works sometimes and other times not. Takes anywhere from 4-8 key turns to start the vehicle sometimes. Other times it starts straight away. Same story with unlocking and locking (red light on key lights up ‘sometimes’ other times not)

2. Yellow Malfunction message on dash with 2 gears (have replaced starter motor with reconditioned unit, but malfunction message still comes up). Maybe something to do with P0C3100 and P143400 codes?

Note - car drives perfectly upon start up but loses noticeable electric drive power after ‘Malfunction’ message shows up. Then continued to cycle/regulate power output.


3. Front radiator fan runs quite loud for about 20 - 30 seconds after turning car off. Likely P012800 fault? Even after replacing thermostat?


Can provide more info if needed.
Any helpful input will be greatly appreciated, thank you
