Lamborghini Urus Transmission Malfunction with Aftermarket 24” wheels

Lamborghini Urus Transmission Malfunction with Aftermarket 24” wheels-cover

Problem:

Many Lamborghini Urus owners experience transmission warning messages after installing aftermarket 24” wheels, or even 23” aftermarket wheels, particularly when paired with widebody kits such as those from 1016 Industries or Novitec. The vehicle may display errors like “Transmission: Malfunction! You can continue driving. See owner’s manual” or “Gearbox malfunction: you can continue driving. See owner’s manual.” These warnings are typically caused by the Transmission Control Module (TCM) detecting a mismatch in rotational circumference between the front and rear axles, often due to incorrect tire sizes or non-OEM tires lacking the factory-specified Lamborghini L-logo.

Upon diagnostics, a common fault code found is P1B8000 – Front/Rear axle circumference, implausible. This issue stems from the transmission and drivetrain systems expecting certain parameters based on OEM specifications. Oversized aftermarket wheels or mismatched tire profiles significantly alter these parameters, triggering safety protocols. If you have recently installed aftermarket 24” wheels or modified your Urus with a body kit such as a 1016 widebody kit, and are now facing transmission or gearbox malfunction warnings, it is important to address this immediately.

Solution:

At the Mechatronic Diagnostics department of VAG Programming, we offer a custom tuning and programming solution specifically designed to resolve the transmission malfunction issues caused by aftermarket 22”, 23”, or 24” wheels on the Lamborghini Urus, including the Urus S, Urus Performante, and Urus SE. Our specialized software recalibrates the vehicle’s Transmission Control Module (TCM) and related systems, eliminating the need for OEM tires with the Lamborghini L-logo and allowing compatibility with virtually any brand tire or wheel setup.

This solution is ideal for Lamborghini Urus vehicles fitted with widebody kits from 1016 Industries, Novitec, or other custom body enhancements, where larger and more aggressive wheel setups are commonly used. By correcting the front/rear axle circumference data and disabling the factory’s strict monitoring protocols, our programming removes false fault codes such as P1B8000 – Front/Rear axle circumference, implausible and prevents transmission or gearbox malfunction warnings from appearing.

If you’ve upgraded to larger wheels or installed a widebody kit and are now facing drivability warnings or fault codes, contact VAG Programming for expert diagnostics and reliable custom tuning. Our solution ensures optimal vehicle performance and system harmony, no matter your wheel or tire configuration.

Result:

After completing our custom recalibration service, Lamborghini Urus owners have reported the immediate disappearance of all transmission and gearbox malfunction warnings, including the infamous “Transmission: Malfunction! You can continue driving” and “Gearbox malfunction” messages. Fault code P1B8000 is successfully eliminated from the ECU, and the vehicle operates as intended with aftermarket 22”, 23”, and 24” wheels—whether paired with widebody kits or not. Drivers experience smoother gear shifts, no drivability issues, and full compatibility with their custom setups, without the need to revert to OEM tires or wheels. This ensures both aesthetics and performance are uncompromised.

Conclusion:

If you’re encountering TCM or transmission-related warnings after upgrading your Lamborghini Urus with larger wheels or a widebody kit, know that you’re not alone—and the issue can be expertly resolved. At VAG Programming, we provide tailored software solutions that correct axle circumference discrepancies and restore full functionality to your luxury SUV. Don’t let performance warnings limit your driving experience or diminish your custom build. Contact VAG Programming today for professional diagnostics, recalibration, and peace of mind.
