           VW CREDIT, INC. COMMENCES ACCUMULATION PERIOD FOR DEALER
            LOAN BACKED CERTIFICATES, SERIES 1996-1 ISSUED BY THE
                      VOLKSWAGEN CREDIT AUTO MASTER TRUST

AUBURN HILLS, Mich.--VW Credit, Inc. today announced that it had taken all
action necessary to commence the Accumulation Period for the $375,000,000
Floating Rate Dealer Loan Backed Certificates, Series 1996-1, issued by the
Volkswagen Credit Auto Master Trust.

     Under the applicable transaction documents, VW Credit, as Servicer, may
elect to cause principal on the Certificates to be paid in full before the April
2001 distribution date.  On February 9, 2000, the Servicer notified the Trustee
of the trust that the Servicer had made that election.  Based on that notice,
the "Principal Payment Date Establishment Date" will be March 15, 2000 and the
"Initial Accumulation Period Commencement Date" will be April 1, 2000. This
means that on monthly distribution dates with respect to the Accumulation
Period, principal collections on the underlying receivables will be deposited in
the "Principal Funding Account" where those collections will be held (or
"accumulated") for the purpose of paying principal to the holders of the
Certificates.

     It is currently anticipated that principal will be paid in full to the
holders of the

Certificates on the June 15, 2000 distribution date. However, if insufficient
collections are received by the Servicer prior to May 31, 2000 to pay principal
in full by the June 15, 2000 distribution date, then it is anticipated that
principal on the Certificates will be paid in full on a future distribution date
on which sufficient funds are available for that purpose.

     The information in this Press Release summarizes certain provisions of the
transaction documents.  For a more detailed description, please refer to the
Prospectus and Prospectus Supplement dated March 14, 1996.  This letter is
qualified by reference to the terms of the transaction documents.

     The above referenced transaction is part of VW Credit's overall asset
securitization program.  The Company expects asset securitization to maintain an
important role in the Company's overall funding strategy.
