Coolant level below minimum

[dolcevita4]

Hi, I've just bough audi a4 b7 1.9 tdi (115) and the problem I'm experiencing is weird. Basically when i bough the car i realised the coolant water was about 1.5cm below minium so i topped it up, few days later it went back to the same level approx 1.5 cm below minimum and no matter how often i fill it up it always goes down to excatly the same level. Any ideas?

You checked for any leaks?
Leave the car running over a dry part of floor and check for leaks.

I believe the head gasket is gone, I've only bought it a week back so I'm gonna fetch it back where I bought it from and see what they say.
