4H0819011 Audi HEATER

This thing is basically a small radiator, but instead of cooling down engine coolant, it heats the air that comes into your cabin. Coolant from the engine flows through it, and the blower motor forces air across the fins, warming everything up. It’s how you get heat in your car. It’s a pretty simple idea, actually. It sits inside the dashboard, usually tucked away behind the center console. Coolant comes from the engine, flows through these little tubes within the core, and the heat transfers to the air blowing into the vents. It's part of the whole heating and ventilation system, working with the blower motor, controls, and ductwork. You’ll notice if it fails; you’ll get cold air even when the heat is cranked up, or you might smell a sweet, sickly odor – that’s usually coolant leaking. Well, obviously, warmth! It keeps you comfortable when it’s freezing outside, and more importantly, it helps defrost your windshield. A clear windshield is a safety thing, obviously. If the heater core fails, it can also cause coolant to leak into the cabin, which is a mess and can fog up your windows, making it hard to see. It’s one of those things you don’t think about until it doesn’t work. If you’re looking to replace one, places like Fixparts Online usually have a good selection, and they’re not too bad on price. Getting a good quality one is important, though; you don't want to be dealing with leaks down the road. Drive with confidence: Heater Core (MPN 4H0819011) is backed by a 12-month warranty!
