Grey or white smoke while hard accelration

So im not quite sure wich one it is cause i have factory tinted rear windows. All the worst case scenarios are popping in to my head but can anyone say what could cause this? I have checked coolant and oil levels regularly and everything looks normal. I remember reading about this way back before and someone said it could be just condensation water or rain water or something like that? Maybe pcv valve?

Car is 2015 2.0 tsi octavia rs and dsg transmission. 194000 on the clock now.
