If the RPS plate of the Monocoque chassis is not present, a new RPS plate has to be installed Warning: If any doubt regarding this procedure, contact your Bugatti contact. Do NOT drive/move or lift the car within 24h of the repair. Technical Bulletin 16‐03‐003BUG RPS Plate March 2016 Page 2 of 11 Issue 1 Procedure: 1. Check that the RPS plate is not dislocated from the monocoque. The RPS plate must not move during the hand verification (Do Not use tools). If the RPS plate is not in place or is loose, see the RPS installation procedure below 2. Mechanically clean the RPS plate and surrounding area as shown on Fig. 1 Fig 1: Mechanically cleaned RPS‐ Plate (Surrounding and bottom surface) 3. Install the drilling gauge as shown on RPS installation drawing (Fig. 2), check the gauge position (Fig. 3‐5) prior to securing.

End of procedure Technical Bulletin 16‐03‐003BUG RPS Plate March 2016 Page 9 of 11 Issue 1 1 2 3 4 FRONT New RPS Plate installation procedure: If the RPS Plate is not present on the vehicle, a measurement of the RPS insert has to be performed to select appropriate RPS Plate. 1. Make sure the RPS tap is removed and clean the RPS insert with Brake Cleaner 2. Use the depth probe of a Vernier calliper to measure the distance between the insert and the Monocoque Chassis 3. Repeat the measurement for the four measurement points of each missing RPS plate. Record the measurement values Technical Bulletin 16‐03‐003BUG RPS Plate March 2016 Page 10 of 11 Issue 1 4. Calculate the average of the 4 measurements , and define appropriate RPS plate according following table (to be confirmed according RPS plate) Average distance from Insert to Monocoque RPS plate thickness to be used 1,00 to 1,50 3,00 tbc 1,51 to 2,00 2,50 tbc 2,01 to 2,50 2,00 tbc 2,51 to 3,00 1,50 tbc 5. Mechanically clean contact surfaces between Monocoque and RPS plate with sandpaper grit 80 – 100 6. Install the selected RPS Plate on the Monocoque and the drilling gauge Drill 3 holes dia. 5mm with max depth 30mm (including drilling gauge height) 7. Remove drilling gauge and deburr RPS Plate holes 8. Degrease the RPS plate and Monocoque RPS area with Brake Cleaner and let it dry for about 10 min 9. Apply a thin film of the structural adhesive 3M Scotch‐Weld DP 490 (DA 001 730 A2) on the selected RPS Plate 10. Install the selected RPS Plate on the Monocoque using drilling gauge installation bolt 11. Install and expand the 3 blind rivets Typ: Monobolt 2774 ø 4,8 mm (aluminium) with EPDM seal (Fig. 7‐9) Technical Bulletin 16‐03‐003BUG RPS Plate March 2016 Page 11 of 11 Issue 1 12.

The analysis was conducted and concluded – in January 2012 The repair solution was available internally – in February 2012. On 11 of March 2016 the matter was brought to the product safety committee and a defect determination was made. Description of Remedy : Description of Remedy Program : Reference Plates will be inspected and replaced if necessary and all plates will be riveted and sealed to prevent corrosion. Bugatti will cover all the costs involved for the repairs. How Remedy Component Differs from Recalled Component : Presence of rivets and seal component on the RPS plate Identify How/When Recall Condition was Corrected in Production : First production car with modified Monocoq w27/2012 Part 573 Safety Recall Report 16V-166 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 Recall Schedule : Description of Recall Schedule : Dealer and Customer notifications : TBD Planned Dealer Notification Date : NR – NR Planned Owner Notification Date :NR – NR * NR – Not Reported
