This is a part warranty, not an Ebay return policy. Due to buyers abusing the Ebay return system, we no longer have any return policy and do not accept returns. We are not a free troubleshooting ECU loaner service -- you cannot install and use our ECU to determine that your problem was something else, and return it because you don't need it anymore. You are responsible for accurately diagnosing your vehicle's requirements. Please make certain that you in fact need an ECU before you purchase it -- there are no returns/refunds. If you buy it, you own it.
Any questions please message us
