Compatible Vehicles

This kit is engineered for direct compatibility with the following platforms:

• Bentley Bentayga
• Lamborghini Urus
• Porsche Cayenne 2018–2023
• Porsche 911, Carrera 992
• Porsche Taycan

What’s Included

• OBD Coding Dongle for 1-car automatically updates battery type configuration via the diagnostic port
• Hardware Kit — 100% tested, brand new components for reliable installation
• 1-Year Warranty — full coverage on all included parts

How It Works

Modern luxury vehicles store the battery type (lithium vs. AGM) and capacity in the vehicle’s control module memory. Simply swapping the physical battery without updating this configuration will trigger persistent error codes, warning messages, and incorrect charging behavior.

Our kit solves this in three steps:

1. Replace the battery — Install a 92Ah AGM battery (recommended specification)
2. Connect the OBD dongle — Plug into the vehicle’s OBD port to automatically rewrite the battery configuration
3. Remove the dongle — Once coding is complete, disconnect and store for future use

Critical Requirements

Reversing the Procedure

If you ever need to revert to a lithium battery, the OBD dongle cannot be used for the reverse process. You will need a full diagnostic tool (such as PIWIS, VCDS, or ODIS) to manually restore the original lithium battery configuration.

Frequently Asked Questions

Will I get any error codes after installing the AGM battery?

No. When the OBD dongle is used to update the battery configuration, the vehicle will recognize the AGM battery correctly and operate without errors — exactly as documented in official manufacturer service information.

Can I use a different capacity battery, like 80Ah or 105Ah?

No. The system is calibrated for 92Ah. Using a different capacity will cause charging system faults and may damage the battery or vehicle electronics. Always use a 92Ah AGM battery.

Do I need to keep the OBD dongle connected after coding?

No. The dongle only needs to be connected during the coding process. Once complete, remove it and store it safely. The configuration is permanently written to the vehicle.

Can I use the dongle to switch back to a lithium battery later?

No. The dongle is designed for lithium-to-AGM conversion only. Reversing to lithium requires a professional diagnostic tool with manufacturer-level software access.

Is this an official OEM tool?

This is an aftermarket solution engineered to perform the same battery type coding procedure documented in official Bentley, Lamborghini, and Porsche service manuals. The result is identical — zero errors, full compatibility.
