Fuel & Ignition System

Tank Ventilation System

The compact tank vent valve (TEV-5) in the engine compartment is designed for a higher throughput, especially in the case of small pressure differences compared with the previously installed valve (TEV-2). The tank vent line is routed directly from the tank vent valve in to the intake pipe.

Carbon Canister

The functionality of the tank vent systems/carbon canister corresponds to that of the 987/997 vehicles. USA vehicles have a carbon canister with tank leakage diagnostic module (DM-TL) which is located in the front luggage compartment.
