This used OEM heater return hose / line (4H0819334N) was removed from a donor Audi, a genuine factory part for the 4.0L twin-turbo V8 in A8 Quattro and S8 models. Also known as a heater return hose or line, it carries hot coolant from the heater core back to the engine. When this rubber or molded hose fails, expect coolant drips under the dash or a loss of cabin heat.
