Schedule 13D

Page 7 of 14

This Amendment No. 4 (the “Amendment”) to the statement on Schedule 13D initially filed on December 28, 2006 (the “Initial Schedule 13D”), as amended by Amendment No. 1 thereto filed on January 30, 2007, as amended by Amendment No. 2 thereto filed on March 16, 2007, as amended by Amendment No. 3 thereto filed on September 10, 2007 (as amended by Amendment No.1, Amendment No. 2 and Amendment No. 3, the “Amended Schedule 13D”) by Merrill Lynch & Co., Inc. (“ML&Co.”), Merrill Lynch, Pierce, Fenner & Smith Incorporated (“MLPF&S”), Merrill Lynch Financial Markets, Inc. (“MLFM”), Merrill Lynch Bank & Trust Co., FSB (“MLTFSB”) and Merrill Lynch International (“MLI”) (collectively, the “Reporting Persons”), relates to shares of Common Stock, par value $0.01 per share (the “Shares”) of Delphi Corporation (the “Issuer”), and is being filed to amend the Amended Schedule 13D as specifically set forth below.

The information set forth in the Exhibits to this Amendment is hereby expressly incorporated herein by reference, and the responses to each item of this Amendment are qualified in their entirety by the provisions of such Exhibits. 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 2. Identity and Background.

Item 2 is amended as follows:

The name, present principal occupation or employment (and the name, principal business and address of any corporation or other organization in which such employment is conducted), and citizenship of each director of ML&Co. is set forth in Schedule I-A hereto and is incorporated herein by reference. Mr. Virgis W. Colbert, a director of ML&Co., was also a director of the Issuer. According to a Form 4 filed on October 3, 2005, Mr. Colbert owned 79,416 restricted stock units that represent an entitlement to an equivalent number of shares of the Issuer as of October 3, 2005. Mr. Colbert voluntarily recused himself from any deliberations of the board of directors of the Issuer relating to the transaction described in Item 4. On December 31, 2006, Mr. Colbert retired as a director of the Issuer. Mr. Colbert had previously reported ownership of 79,416 phantom stock units he’d received under the Issuer’s Deferred Compensation Plan for Non-Employee Directors. Pursuant to the Issuer’s Deferred Compensation Plan for Non-Employee Directors, seven months after Mr. Colbert’s retirement from the Issuer’s board of directors, Mr. Colbert received a payment of $203,431.68 in respect of the 79,416 phantom stock units, and such phantom stock units were cancelled.

Item 4. Purpose of Transactions.

Item 4 is hereby amended by adding the following:

On April 4 and 5, 2008 Appaloosa delivered notices of termination of the Equity Purchase and Commitment Agreement, dated August 3, 2007, as amended on December 10, 2007 (the “December 10th Investment Agreement”), copies of which are attached as Exhibit 51 of the Schedule 13 D/A filed by Appaloosa, dated April 4, 2008 and Exhibit 52 of the Schedule 13 D/A filed by Appaloosa, dated April 8, 2008. As a result of the termination of the December 10th Investment Agreement and the agreements related thereto, the Reporting Persons are no longer a member of any “group” (within the meaning of Section 13(d) of the Securities Exchange Act of 1934) that may have been formed (or deemed to have been formed) as a result thereof, and the Reporting Persons, individually and in the aggregate, are no longer the beneficial owners of more than five percent of the Shares.

Other than as described in this Amendment, to the best knowledge of the Reporting Person there are no contracts, arrangements, understandings or relationships (legal or otherwise) between the Reporting Person and any other person, with respect to any securities of the Issuer, including but not limited to, transfer and voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies, or a pledge or contingency the occurrence of which would give another person voting power or investment power over the securities of the Issuer.
