CCV Cleanout with Pictures

Would this only apply to driving in winter? I don't drive the X at all in the winter.
Could I just inspect (if oil inside & TB area) replace the hoses? and Pressure Regulator Valve (Repair Kit)

There are a number of reasons you my get condensation (coolant leak, cold rainy weather, etc.) I would inspect the diaphragms every year or two (takes 10 min.) and carefully inspect the vent hoses (any vacuum leak will cause the valves not to close and they'ii start sucking oil & ambient air). Any time the vehicle runs bad or starts using excessive oil - check the hoses and diaphragms right away. BMW rubber & plastic parts are known failure points.
