Lamborghini Urus Windshield 4ML845099

the part number 4ML845099 refers to the Front Windshield (Acoustic Glass) for the Lamborghini Urus.

Because the Urus is a high-tech vehicle, the windshield is not just a piece of glass; it is a complex component that integrates several vehicle systems. Depending on the suffix (e.g., 4ML845099A, B, or C), the glass will have different features like Head-Up Display (HUD) compatibility or internal heating elements.

1. Technical Specifications

• Part Number: 4ML845099

• Type: Laminated Safety Glass with Acoustic Insulation (to reduce wind noise at high speeds).

• Integrated Features:

  • Camera Bracket: For the ADAS (Advanced Driver Assistance Systems) camera (Lane Keep Assist, Traffic Sign Recognition).

  • Rain/Light Sensor Mount: For automatic wipers and headlights.

  • HUD Compatibility: If your car has a Head-Up Display, you must use the HUD-specific version of this part number. Standard glass will cause the HUD image to appear “ghosted” or blurry.

  • Heating Elements (Optional): Some versions feature nearly invisible wires for rapid defrosting.

2. 2026 Market Pricing

Replacing a Urus windshield is a significant expense, often handled through specialized insurance glass coverage.Wrning: Using non-OEM glass can often interfere with the calibration of the ADAS cameras, leading to “System Fault” messages on the dashboard.

3. The Calibration Factor

The most important part of replacing the 4ML845099 windshield is the ADAS Calibration.

• After the glass is set, the camera mounted to the windshield must be recalibrated.

• This requires a specialized facility with digital targets.

• Cost of Calibration (2026): Generally adds to the labor total. If this isn’t done, features like Adaptive Cruise Control and Lane Departure Warning may fail or behave dangerously.

4. Key Issues & Maintenance

• Chip Repair: Due to the steep angle of the Urus windshield and its high-speed capabilities, small stone chips can quickly turn into large cracks. It is recommended to fill chips immediately.

• Acoustic Layer: If the windshield is replaced with a non-acoustic version, you will notice a significant increase in cabin noise above $120\text{ km/h}$ ($75\text{ mph}$).

• VIN Notch: Ensure the replacement glass has the correct “window” for the VIN (Vehicle Identification Number) located on the driver’s side dash.
