Lamborghini Urus Roll Stabilization Control Module 971907156Q

the part number 971907156Q identifies the Control Module for Active Roll Stabilization (often called the EAWS module). This unit is the “brain” behind the electromechanical anti-roll bars that allow the Lamborghini Urus to corner flat despite its high center of gravity.

Because the Urus shares the MLB Evo platform, this part is often interchangeable with high-end siblings like the Porsche Cayenne (9Y) and Bentley Bentayga, though the software “flash” is unique to Lamborghini’s aggressive tuning.

1. Technical Role of the Module

• Active Anti-Roll: It manages the 48V motors located in the center of the front and rear anti-roll bars.

• Torque Distribution: Within milliseconds, it calculates how much resistance to apply to each corner of the car to counteract body roll.

• Off-Road Mode: In Sabbia (Sand) or Terra (Dirt), it can essentially “decouple” the bars to allow for maximum wheel articulation.

2. 2026 Market Pricing

This is a high-tech electronic component. Pricing varies significantly between buying a “virgin” new unit versus a used one.

3. Symptoms of a Faulty 971907156Q

If this module fails, you will likely see one or more of the following:

• Dashboard Warning: “Chassis System Fault” or “Active Roll Stabilization Unavailable.”

• Fixed Handling: The car may feel unusually “stiff” over bumps or, conversely, show excessive body lean in corners because the bars have defaulted to a neutral/fail-safe state.

• 48V Battery Drain: A short in the module can sometimes lead to issues with the 48V electrical subsystem.

4. Critical: Coding and Programming

In 2026, you cannot simply “swap” this module and drive away.

• Component Protection: Like most VAG-group parts (Audi/Lamborghini/Porsche), this module is linked to the vehicle’s VIN via Component Protection.

• Programming: A replacement 971907156Q must be initialized using ODIS (Offboard Diagnostic Information System) with an online connection to Lamborghini’s servers to authorize the part. Without this, the module will remain locked and non-functional.

5. Cross-Compatibility Note

While the hardware part number (971907156Q) may appear on a Porsche Cayenne, do not buy a Porsche-coded unit for a Urus unless you have a specialist (like McMedics or a high-end tuner) who can re-flash the Lamborghini-specific firmware onto the chip. The suspension geometry and weight distribution profiles are different.
