To accurately identify colours of body panels or interior trimmings we may ask you to take a look at the build sticker for your car. All Audi cars have a unique build sticker which can be found in the front of the service book and also in the spare wheel well area of the car. This contains details of your car specifically and will show the paint code, interior colour codes and several other important details unique to your car.
From this build sticker we can gain the following key information:
The engine is a BHT (W12 6.0 Litre)
The Gearbox is a GXL with an HCL rear diff
The bodywork is Silver with a paint code of LY7Q
The interior is Platinum LF
