Description
This Bosch heater flap actuator is a genuine Audi HVAC air distribution motor for the Audi A6 C5. The primary OEM number is 4B1820511, with Bosch reference 0132801126. It is designed to control an internal heater or climate flap within the dashboard air distribution system.
Its job is to move the HVAC flap precisely so the system can direct airflow and regulate cabin air routing as requested by the climate controls. When operating correctly, it helps the heating and ventilation system respond smoothly to temperature and vent position changes.
Common signs of a faulty unit include clicking noises from behind the dashboard, airflow stuck on one vent setting, uneven cabin temperature, or poor response when changing heater or ventilation settings. A failed actuator can also cause the flap to stop moving or move inaccurately.
This is a used original part, removed from a vehicle and tested before sale. Please match 4B1820511 and 0132801126 before ordering. Professional installation is recommended, and adaptation or calibration may be required after fitting where applicable to the HVAC system.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
