5. How much does the diagnosis cost?

Each customer's first diagnosis is free. From the second one on, the diagnosis fee is provided via WhatsApp before you ship the module, and you only ship it if you agree. The repair is only carried out if you approve the quote. If the module cannot be repaired, we do not charge for the diagnosis. The return shipping of the module is at your expense.

We inform you via WhatsApp with an explanatory technical report. We do not charge for the diagnosis and we return the module to you (return shipping at your expense); we do not discard customers' modules. In this situation, we can offer a replacement module (new or tested used) compatible with your vehicle.

Yes. 90 calendar days from receipt of the repaired module. If the same defect recurs within this period, we redo the repair at no cost, including shipping. See the full details in the Technical Warranty Policy.

Confirm the destination address via WhatsApp before shipping.
