No, your MKIII probably never came with a cabin air filter from the VW Factory. The MKIII Owner's Manual shows the cabin air filter, but it had to be an option that nobody took. Some people have retrofitted their MKIIIs with cabin air filter parts from MKIVs (part look exactly like the parts pictured in the MKIII Owner's Manual. Very simple upgrade, you just have to remove the right side cowl from under the hood, take off the two plastic nuts that hold the MKIII ventilation system plastic screen in place, replace with the MKIV filter base, place a filter on top, had secure the filter in place with the snap on plastic filter retainer/holder.
Pros: very simple upgrade
