Help!! Parasitic drain b7 A4
 

I recently bought a 2005 1.9 audi a4 b7, I'd drive the car park it up and 4 hours later battery flat can't even unlock the car, not even enough for interior lights, it will only happen every few days but today my central locking has gone altogether, found wires botched in the door repaired them still have the problem, also put a new battery in the car last week, any advice appreciated
