🔄 Method 1: Golf Mk7 Climate Control Reset: Automatic HVAC Recalibration (via Ignition)

This is the most common and safest method:

1. Turn ignition ON (do not start the engine)

2. Turn climate control OFF (press the OFF button)

3. Press and hold both the "AC" and "Air Recirculation" buttons simultaneously

4. Hold for about 5-10 seconds

5. Release the buttons — you may hear actuator noises behind the dashboard

6. Wait about 30-60 seconds until the system finishes recalibration

7. Turn the ignition OFF, then back ON and test the climate system

🔌 Method 2: Battery Disconnect Reset

If the button reset doesn’t work, try this:

1. Open the hood and disconnect the negative battery terminal

2. Leave it disconnected for 10–15 minutes

3. Reconnect the battery

4. Start the car — the HVAC system will automatically recalibrate itself on startup

Note: This may reset other systems (radio presets, clock, etc.)

⚙️ Method 3: Using VCDS (Advanced)

For users with VCDS (VAG-COM) diagnostic tools:

1. Plug in the VCDS cable and open the software

2. Go to [08 - Auto HVAC]

3. Select Basic Settings

4. Choose "Group 001 – Actuator Calibration"

5. Click Go

6. Wait for the process to complete, then exit

This is especially useful for recalibrating air flap motors after replacement or fault.

🛠️ Tips After Reset:

• Let the system run for a few minutes to normalize

• Listen for clicking or mechanical sounds (they should stop within 1–2 minutes)

• If airflow or temperature is still incorrect, there may be a faulty blend door actuator or climate control module
