Cabin Filter, Charcoal Activated, CoolXpert (MK4)
A good preventative maintenance item, if not changed or checked regularly the cabin air blower will be working harder to draw air through the filter. This could lead to early blower motor failure and or failure of the blower motor speed resistors. It also lets the defrost system work better on damp or cold days.
A Mahle brand may be shipped if the CoolXpert brand is not available at the time of order.
