Audi Coolant Reservoir Hose, OEM 7L8122447G — a used genuine line removed from a donor vehicle. Also known as a coolant reservoir hose or coolant line, this is the hose that connects the expansion tank to the cooling system on the 3.0L V6 diesel (TDI) engine. When the hose fails, you may notice coolant puddling under the engine bay, a low coolant warning, or gradually rising temperatures from a slow leak.
