Audi secondary air pump hose / line / damper 4G0129955A—a used genuine OEM part from a donor vehicle. This assembly, also superseding 4G0129953A, delivers air from the pump to the exhaust manifold during cold starts on the 4.0L twin-turbo V8 (found in S6, S7, RS7). When the rubber damper or line cracks, it triggers a check-engine light and can cause a rough idle or insufficient air flow. Inspect the damper section for wear; replacing this hose restores proper emissions system function.
