     This Amendment No. 18 (this "Amendment") to the Schedule 13D (the "Initial
Schedule 13D") initially filed on March 16, 2006 by the Reporting Persons (as
defined in the Initial Schedule 13D), as amended on August 1, 2006, August 29,
2006, December 19, 2006, January 18, 2007, March 2, 2007, March 12, 2007, May
15, 2007, July 6, 2007, July 10, 2007, July 20, 2007, July 23, 2007, August 3,
2007, November 2, 2007, November 8, 2007, November 16, 2007, December 12, 2007
and March 7, 2008 relates to the common stock, $0.01 par value per share (the
"Common Stock"), of Delphi Corporation, a Delaware corporation (the "Issuer"),
and is being filed to amend the Reporting Persons' previously-filed Schedule 13D
as specifically set forth below.

     Certain information contained in this Schedule 13D/A relates to share
ownership of persons other than the Reporting Persons. The Reporting Persons
expressly disclaim any liability for any such information and for any other
information provided in this Amendment that does not expressly pertain to a
Reporting Person, as such term is defined in Item 2 of the Initial Schedule 13D.

     Unless otherwise indicated, all capitalized terms shall have the meanings
ascribed to them in the Initial Schedule 13D, and unless otherwise amended
hereby, all information previously filed remains in effect.

Item 4 is hereby amended by adding the following:

     On March 6, 2008, ADAH filed its objection to the Issuer's 1142 Motion
(Docket No. 12978) (the "ADAH Objection"). On March 7, 2008, the Bankruptcy
Court held a hearing on the Issuer's 1142 Motion (the "Hearing"). At the
conclusion of the Hearing, the Bankruptcy Court denied the Issuer's 1142 Motion,
determining that GM's agreements in connection with the Revised Exit Financing
were prohibited by section 5(p)(ii) of the EPCA. The Bankruptcy Court also
determined that it would require an evidentiary hearing conducted pursuant to
the adversary proceeding rules to decide the other issues raised by the parties
in connection with the Issuer's 1142 Motion, including whether the changes
reflected by the Revised Exit Financing from the Debt Financing contemplated by
the EPCA (e.g., reducing the aggregate amount of the financing from $6.8 billion
to $6.1 billion) were also prohibited by the EPCA. A copy of the Bankruptcy
Court order denying the Issuer's 1142 Motion is attached hereto as Exhibit 50.

     On March 8, 2008, the Issuer delivered to ADAH a further revised proposed
exit financing package (the "Further Revised Exit Financing") which contains
terms that are substantially identical to the Revised Exit Financing, except
that the materials add a subsidiary of GM to participate in the purchase of the
$2 billion first lien note. The Issuer has made public statements that it
believes the Further Revised Exit Financing is consistent with guidance the
Issuer believes it received from the Bankruptcy Court at the Hearing and is
therefore permitted by the EPCA. By correspondence dated March 9, 2008, ADAH,
Del-Auto, UBS, Merrill and Pardus DPH informed the Issuer that, (a) for all the
reasons set forth in the February 13 and 24 letters and the ADAH Objection, the
Further Revised Exit Financing remains inconsistent with, and if funded would
not satisfy the conditions of, the EPCA, and (b) they were reserving all of
their rights, including with respect to all prior, present and future proposals.

                                  Page 12 of 16

     There can be no assurance that the disputes described above can be resolved
by mutual agreement or in the Bankruptcy Court and there can be no assurance
that the transactions contemplated by the EPCA will be consummated.

  Item 7 is amended to add the following exhibits:

     50   Order Denying (1) Emergency Motion of A-D Acquisition Holdings, LLC
          for (I) a Continuance and (II) an Order Vacating the Order to Show
          Cause and (2) Expedited Motion Under 11 U.S.C. ss. 1142(b) and Fed. R.
          Bankr. P. 3020(d) for Implementation of Debtors' Confirmed Plan of
          Reorganization.
