Vemo V10-77-1084 HVAC Blend Door Actuator

VEMO HVAC Blend Door Actuator for Audi and Volkswagen

The Vemo V10-77-1084 is an electric HVAC blend door actuator for electronically controlled air conditioning systems. It controls the temperature regulating flap to help direct cabin air to the requested temperature on supported Audi and Volkswagen applications.

Built to OE-style dimensions and application-specific fitment, this HVAC blend door actuator is a direct replacement option for vehicles using OE reference 5Q0898511G. The VEMO line focuses on precise electronic control components for climate systems, making this part a practical choice when the temperature flap motor is no longer responding correctly.

Key Features

• Electric operating mode for HVAC temperature flap control
• OE reference: 5Q0898511G
• Dimensions: 75 mm length, 60 mm width, 42 mm height
• Lightweight design at 0.088 kg
• Application-specific replacement for left-side HVAC temperature regulating flap systems
• Compatible with Audi A3, A3 Quattro, A3 Sportback e-tron, S3, and Volkswagen Golf-family models listed below

Detailed Description

The VEMO V10-77-1084 HVAC blend door actuator is used in climate control systems that rely on an electric motor to move the temperature regulating flap. When the actuator fails, the system may stop blending hot and cold air correctly, which can affect cabin comfort and temperature consistency. This part cross-references OE number 5Q0898511G for the same application.

What It Helps Solve

• Inconsistent cabin temperature from a stuck or slow-moving blend flap
• Noisy HVAC actuator operation behind the dash
• Loss of proper hot/cold air mixing in the climate control system
• Temperature output that does not match the selected setting
• Faults related to the left-side temperature regulating flap motor

Installation Notes and Tips

Verify OE number 5Q0898511G and confirm the vehicle uses an electronically controlled air conditioning system before ordering. Access is typically behind the dashboard or HVAC housing, so compare the original actuator’s connector, mounting points, and orientation with the replacement part before installation. After installation, recalibrate or cycle the climate control system if the vehicle procedure requires it.
