This tweak allows you to control your Jetta’s windows using the key fob. You can roll the windows up or down remotely, providing added convenience, especially in hot weather.

How to Enable Window Control from Key Fob:

1. Select Module 09 (Central Elect).
2. Go to Section 07 (Coding).
3. Select Byte 03.
4. Enable Bit 5.

2.3 Disable Audible Locking Signal

The audible locking signal, or “beep,” can be disabled to provide a quieter locking experience. This is particularly useful in residential areas where you want to avoid disturbing others.

How to Disable Audible Locking Signal:

1. Select Module 09 (Central Elect).
2. Go to Section 07 (Coding).
3. Select Byte 05.
4. Disable Bit 1.

3. Find Byte 06.
4. Change the value from 0 to 1.

2.5 Tear Drop Wiping

Tear drop wiping is a feature where the windshield wipers perform an additional wipe a few seconds after using the windshield washer. This clears any remaining streaks and improves visibility.

2.6 Come Home/Leave Home Lighting

Come Home/Leave Home lighting activates the headlights or fog lights when you unlock or lock your car. This provides added visibility when approaching or leaving your vehicle in dark conditions. Enabling this feature might require additional hardware or coding adjustments, depending on your Jetta’s model and equipment.

3. What are the Risks Associated with VCDS Tweaks?

While VCDS tweaks can enhance your Jetta, they also come with risks. Incorrect coding can lead to system malfunctions or even damage to the vehicle’s electronic components. Always proceed with caution and back up your original settings before making any changes.

Incorrect coding can lead to a variety of problems. According to a report by the National Highway Traffic Safety Administration (NHTSA), unintended acceleration and braking issues have been linked to improper ECU modifications. Always verify the coding information and ensure compatibility with your vehicle’s specific configuration.

3.1 Potential for Damaging ECU

The most significant risk is the potential for damaging the ECU. Incorrect coding or flashing can corrupt the ECU’s software, rendering it unusable and requiring costly replacement or reprogramming.

3.2 Voiding Warranty

Performing VCDS tweaks can void your vehicle’s warranty, especially if the modifications cause issues covered by the warranty. Check with your dealer or warranty provider before making any changes.

3.3 System Malfunctions

Incorrect coding can lead to various system malfunctions, such as:

• Warning Lights: Erroneous warning lights on the dashboard.
• Component Failure: Malfunction of various electronic components.
• Reduced Performance: Decreased engine performance or fuel efficiency.
• Safety System Issues: Problems with ABS, airbags, or other safety systems.
