Audi a4 no power

[Markyy]

My 98 A4 2.4 Had been left standing for about 3 weeks.When i tried to start the engine i found there to be no power/lights nothing, as if the battery had gone beyond flat.I recharged the battery but this made no difference.A mechanic friend of mine said that if the batery had run down over a period of time the cars memory would be affected and would have to be re peogrammed/coded by Audi.Is this correct and are there any mobile mechs who could do this at my place.
