Dead battery

Hey guys ,
its the first time to post here but this forum has been very helpful to me .
I have a skoda octavia mk1 2001 automatic transmission and it runs Very good  only one annoying thing is happening if the car sits for more than 2 days it will have a flat battery , i checked the battery and it was good its less than a 1 year old so i made the parasitic draw test when the key is off and i've pin pointed the circuit that draw electricity when the key is off its  fuse no 13 " stop light " ,  the light doesn't stay on i checked that but still its drawing electricity and i checked the stop light switch and i 've found two wires connected to the circuit i didnt follow the wires yet it was getting darker and couldn't see but i think these 2 wires goes to the relay in the automatic transmission Lock in the lever , i am stuck at this point and don't know what to do , and i tried to take the car for inspection but they say everything is fine -_- , so any help will be appreciated .
