            Core Charge

            A core is some portion of a part that can be recycled or reused by the manufacturer. This helps to reduce product cost and is good for our environment. For this reason a product with a core has an additional charge associated with it. If the old part is returned in reusable condition, the core charge will be refunded.

          Warranty Overview

          At eEuroparts, we stand behind the quality of the products we sell. Every part we offer is backed by a warranty designed to give you peace of mind and protect your investment.

          • What’s Included: Replacement of the defective product (labor and shipping excluded).

          • Proof of purchase (invoice or order confirmation).

          • Photos or videos showing the defective part, order number, date, VIN, and odometer reading.

          • Diagnostic reports or part returns for non-visible issues may be requested.

          • Claims must be truthful, properly documented, and reflect normal consumer use.
