I have been having major probs with flat battery.This coinsided with a nasty smell when heat was on. Turned out the batt area was flooded and this leaded me to finding out about the problem of the con module getting wet. The car has been to MD half doven times but they can not find the fault.They said the module was wet but terminals not green so it should dry out. This as been going on for a year apx.They seem to think that the module "usually" just goes,NOT problematic.The only other symtem i can is the folding mirrors work 50/50 of the time.never seen probs with c locking,windows or alarm etc. I do not want to rerplace the module and its not that. I have had 3 batts,this batt is checked ok.Charging fine.sometimes batt charge lasts a week,3 days or 1! A independent audi garage how would comment on the module said in there experience that the seat needs to come out and the suuronding area dried out with heaters 1st.then check the module and make sure the wires/loom are not wet and corroded.then check for faults etc. As any got any comments on the module? Also what is entailed to get to the module for a look? Banging my head against a wall at the moment.Audi MD just had my car for 8 days.They told me they first charged the batt fully then did drain test.no faults found,done twice.I told them its no good keeping the car inside in the warm with bonnet open.Can they keep it out side in the cold as like at home.following 5 days starts every day at MD.I take it home ,a fairly good distance,3 days later flat!!!!!!! What would you guys do??????????
