Mk6 Golf 2.0 Coolant lose

[danhughes123]

hi
i have been loosing coolant from my golf for the last month now. topping it every week or 2. there are no visible leaks.The oil doesnt appear to be contaminated and there is not white smoke coming from tail pipe. the car has done 35k miles and had a remap 6months ago. was wondering if anyone had any advice.

Thanks Dan
