Order Cancellation
Orders may be cancelled before they ship by calling 1-800-446-0917 or emailing sales@dieselecmexchange.com. Once an order has shipped, it is subject to the return terms below.
Return Eligibility
1. Time Limits. All sales are final (no returns, credits, or refunds) after 60 days. Any damaged or malfunctioning parts must be reported within 5 days of delivery.
2. Authorization. All returns must be authorized prior to shipment. Contact us at 1-800-446-0917 or sales@dieselecmexchange.com to request a return authorization.
3. Customer Remorse Returns. Returns for non-defective reasons (wrong part ordered, changed mind, compatibility issues) are accepted within the 60-day window and are subject to the processing fees outlined below.
Return Method
All returns must be shipped by mail to:
Imperial Auto Services LLC
8208 Brownleigh Drive, Suite 100

Return Shipping Costs
The customer is responsible for return shipping costs on refund returns. Note: the pre-paid shipping label included with your order is for the core return to activate your lifetime warranty — it is not for refund-related returns.
Fees
All units returned are subject to fees on a case-by-case basis. Some cases are as follows:
A.) On all diesel returns there is a 30% processing fee/restocking fee
B.) On diesel modules where the cost of the module is over $400.00 and the module is deemed unrepairable there is a $300.00 fee.
Refund Processing
4. Refund Payments. Refunds will be issued in the same method of payment as the original payment. Refunds are processed within 5–7 business days after the returned item is received and inspected at our facility.
5. Fees Refunded. Refunds will be issued for the merchandise. Shipping and handling charges, including original shipping and handling charges, taxes, and any charges undertaken for returning an item, will not be refunded.
6. No Refunds without Return. Refunds are only issued after receipt of the item intended to be returned.
Conditions and Exclusions
7. No Refunds for Certain Conditions. This policy does not cover parts that fail due to abuse, misuse, neglect, alteration, impact, or accident. The company reserves the right to deny a refund if the company deems that it is not responsible for damages to the part.
8. Condition of Return. You must return an item in the same condition as it was received by you. This includes all packaging such as boxes, bags, and tags, accessories such as cords and remotes, certificates, manuals, and warranty cards, any bonus items and any all items included in a bundle. For items with a manufacturer or factory seal, the seal must be unbroken and intact. Items missing a serial number or UPC can’t be returned.
9. Excluded Categories. There is no refund opportunity for any customer using a part for purposes of an engine swap or similar performance work.
