The accumulator / filter drier works as a filter, removing moisture and contaminants from the refrigerant that flushing cannot clear, which is why replacing it during service is essential.
Backed by Four Seasons' decades of mobile A/C experience and produced in an ISO/TS16949 and ISO14001 certified facility.
What does this A/C accumulator do?
It acts as a filter drier, removing moisture and contaminants from the air conditioning system and holding an internal desiccant that absorbs moisture the refrigerant carries.
Which vehicles does the 33328 fit?
It fits the 1993-1995 Audi 90, 90 Quattro and 90 Series, 1994-1998 Audi Cabriolet, 1996-2001 Audi A4 and A4 Quattro, and 1998-1999 Volkswagen Passat. See the Buyer's Guide tab.
Are seals included?
Yes. The necessary gaskets, o-rings and seal are included to make installation easier.
Why should I replace the accumulator when servicing the A/C?
Contaminants and moisture can't be removed by flushing, and the desiccant can saturate quickly in an open system. Replacement is also required to validate the compressor warranty.
Can I just flush the old accumulator instead of replacing it?
No. Flushing cannot remove the trapped contaminants or restore a saturated desiccant bag, so replacing the accumulator / filter drier is essential.
