To cancel an order, please contact us through our 'Contact Us' page.

All cancelled orders are subject to a minimum 5% cancellation fee (varies by product, see details below) to cover payment processing fees and other overhead costs which are not refunded to ACM Technik.

Some products such as made-to-order wire harnesses cannot be refunded after purchase due to agreements with vendors/manufacturers, as noted on product pages.

ACM Technik accepts returns of most unused, unopened products within 30 days of delivery.*

*Tunes and Tuning Cables/Dongles: Once an order for a tune, tuning cable, or tuning dongle has been fulfilled/shipped, we are no longer able to refund the purchase.

*Activation/Coding Services: All ACM Technik feature activation and coding service costs are 100% refundable prior to the service being performed (excluding cost of remote activation cables). Features that have been activated may be returned within 30 days after your activation appointment for a 50% refund of the cost of the service. Feature(s) must be removed/reverted to stock prior to a refund being issued. For orders that include a remote activation cable, the cable(s) may be shipped back at your expense for a 75% refund of the cost of the "remote" fee.

Additionally, if you already have the DoIP cable and USB adapter from a previous activation or coding job, please do not select the "remote" option for any subsequent purchases. Purchasing the "remote" option for subsequent activation/coding jobs will trigger another cable setup to be shipped to your address. This will not be refunded.
