Removing carbon canister

Information

Only one type of active carbon filter is supplied as a spare part. The supplied hose will have to be adapted to suit the peripheral equipment on the vehicle, depending on the market and equipment type. It may be necessary to pull off the hose and connect the active carbon filter directly to the vacuum lines on the sports flap exhaust system for example. The hose specified in PET must also be used for the US version of the V8 S with sports flap exhaust system and the V8 Turbo. The hose on the active carbon filter must be disposed of in this case.

1. In front of the carbon canister, loosen the cover (heat protection panel -1- ) only at the top middle position of the four fastening screws -four screws 2-. There must be sufficient clearance around the carbon canister for removing and installing it.
