Coolant leak oilfilter housing on 2000 Audi A6 Quattro

There is a coolant leak on the oilfilter housing

Asked by for the 2000 Audi A6 Quattro
the oil filter housing can turn if the oil filter was so tight that excess force was used. this usually breaks the hose on the cooler. replace the hose, tighten the cooler and use a better oil change place.
