Audi A4 2004 1.8T s-line losing battery all battery power every 3 months or so!?

I bought a new battery after my Audi A4 wouldn't start. My friend who is a mechanic fitted the battery for me. After 3 months, I woke up to go to work and the battery was dead. The next day after a couple of jump starts with jump leads my car starts first time and has done for the last 3 months. Yesterday it did the same, wouldn't start! Today, started first time and not had a problem again? Anyone have a clue? Could it be a short circuit? If so where?

The first thing i would do is have the alternator tested.Then the battery tested also have a parastic draw test done if the first two reveal nothing.

Alright then if the battery keeps going dead with the car off you need to have a parstic draw test performed.This will check for excessive draw and they can find the draw with this test.
