I have a 2012 Audi A4 1.8 B8 that have developed the following faults which all seems to be linked with the fuel. Anyone knows what might be the cause if it's something that can be easily resolved? The car seems fine and have been driving it, but I'm a bit worried as fault isn't going away.
P2187 - System too lean at idle bank 1
P0441 - Evaporative emission system incorrect purge flow.
P12A2 - Manufacturer control
