2 error codes

[laur]

Hi guys my second a4 has been sitting for 6 months,it hasn't move all the time and is hasn't been started,I gotit going the other day,did a full service on it inspected all round and seems fine ,but I am getting 2 fault codes:
P0102-mass air flow sensor (g70) signal to low intermittent and
P1857-load signal:error message from ecu (this one is from the brakes module)
My engine light and my ESP light is on,I have cleared the codes but they keep coming back,the only symptom is that the engine stalls when I first start the car,if I revit a bit it won't,i don't see a loos in performance or any thing,just when starting the car it stalls,car was fine when I lefted 6 months ago
Ps.car is an audi a4 2.0 alt engine from 2001
Are the codes connected?any ideas?

Nobody?? I was thinking to change the MAF,for the first code,but what about the second one?

My car threw up some weird errors over the winter (Brakes and esp light). Turns out the battery was struggling to cope and this seemed to be the reason for the mad errors (low battery triggering all sorts of problems). It sounds like a good plan to do the MAF, then run the car for a while to get the battery back up to a well charged state and see if other codes persist.
