Backed by Four Seasons' decades of mobile A/C experience and produced in an ISO/TS16949 and ISO14001 certified facility, this accumulator/filter drier is built for long-lasting performance. Replacing it any time the system is opened or serviced is required to validate compressor warranty.
What does this A/C accumulator do?
It acts as a filter, removing moisture and contaminants from the air conditioning system through a desiccant bag — impurities that cannot be removed by flushing.
Does it come with installation hardware?
Yes. The necessary gaskets, o-rings and seal are included for easy installation.
Which vehicles does part number 33331 fit?
It fits the 1993-1994 Audi 100, 1993-1994 Audi 100 Quattro, 1995-1997 Audi A6, 1995-1997 Audi A6 Quattro, 1995-1996 Audi S6, and 1993-1994 Audi V8 Quattro. Check the Buyer's Guide tab.
Should I replace the accumulator when servicing the A/C?
Yes. Four Seasons states replacement is required to validate compressor warranty and it must be replaced any time the system is serviced.
Why can a leaking system ruin the accumulator?
A leaking or open system can saturate the desiccant bag within a few hours, making the accumulator/filter drier ineffective at absorbing moisture.
