Help Please Fuel related fault codes

[PauloV]

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

That second code could be a failing purge valve and I wonder if that could be consequently causing the lean condition and the first code.

Could be worth getting an Audi specific scan tool on it.
