Complete convertible top for Audi R8 Spyder, year of manufacture 2013, color black

Part Number: 420871011B (Successor: 420871011C) Model Year: 2013 (Facelift Generation) Color: Black (Standard Fabric)

The 420871011B corresponds to the complete “cassette” assembly for the first-generation Audi R8 Spyder (Type 42). In 2013, the R8 received a facelift (LCI) which included minor refinements to the roof operation and seal geometry. This unit is a complex electromechanical and hydraulic system designed to fold in a “Z” pattern over the mid-mounted V10/V8 engine in just 19 seconds.

Technical Specifications

• Fabric Material: 3-layer Sonnenland A5 canvas (highly UV-resistant and acoustic-insulated).

• Operation: Fully automatic hydraulic drive with integrated electric locking.

• Speed Threshold: Operable at speeds up to 50 km/h (31 mph).

• Weight: Approx. 42 kg for the complete mechanical assembly.

• Rear Window: Heated mineral glass, which retracts independently of the roof.

Key Features of the Facelift (2013) Assembly

• Improved Wind Noise Insulation: Facelift models feature thicker seals at the A-pillar and side-window interfaces to reduce whistling at high speeds.

• Z-Fold Geometry: The roof is designed to be extremely compact, taking up minimal space in the stowage box to allow for adequate engine cooling.

• Manual Emergency Override: In the event of a hydraulic failure, the 2013 assembly includes specialized emergency release points located under the rear storage tray (access via the cabin).

Professional Installation & Technical Notes

Replacing a complete R8 roof is one of the most labor-intensive tasks on the 4S/42 platform (estimated 10–12 hours).

1. Roof Cassette Removal: To install the complete assembly, the rear engine lid, side panels, and the rear “tonneau” cover must be removed. This often requires two technicians to ensure the frame remains perfectly square during the lift.

2. Hydraulic System Bleeding: If you are installing a “dry” or new unit, the hydraulic pump must be primed and the lines bled of air. Use only Audi Genuine Hydraulic Fluid (G 004 000 M2). Air bubbles in the lines will cause the roof to “stutter” or stop halfway through its cycle.

3. Micro-switch Synchronization: The assembly contains over 10 hall sensors and micro-switches. After installation, the Convertible Top Control Module (J256) must be calibrated using Audi ODIS. The car needs to “learn” the precise time it takes for each hinge to move to avoid timing faults.

4. Water Management: Verify that the four main drainage channels (two per side) are completely clear. Blocked drains are the leading cause of hydraulic pump failure, as water overflows directly into the motor housing.

Inventory Tip: When storing or shipping a complete top, it must be braced in the “partially open” or “service” position with specialized spacers to prevent the fabric from creasing and the tension cables from stretching.
