Disable DRL with Turn Signal (2012 Only): For 2012 models with LED DRLs, enable the DRL next to the activated turn signal to dim. This involves a more complex procedure detailed in a separate guide. LED DRL Dimming
Emergency Brake Flashing: Activate automatic flashing of brake lights and/or turn signals during hard braking. This feature enhances safety by alerting drivers behind you. Modify bytes 16 in the Central Electronics module.
Coming Home/Leaving Home Lights: Activate the “Coming Home” feature, which illuminates your headlights for a set period after you exit the vehicle. The “Leaving Home” feature requires an auto switch and light sensor. Modify byte 12 in the Central Electronics module. Adjust the activation time in the MFA.
Comfort Turn Signal Count: Change the number of times your turn signals flash with a single tap. The default is usually three, but you can adjust it up to five blinks by modifying the “Comfort Turn Signals (Cycles)” setting in the Central Electronics module’s Adaptation channels.

Wipers

Tear Drop Wiping: Enable an extra wipe after using the windshield or rear window washer. This feature helps clear residual washer fluid. Modify byte 1 for the front wipers and byte 21 for the rear wiper in the Central Electronics module.
Disable Rear Wiper in Reverse: Deactivate the automatic rear wiper activation when shifting into reverse while the front wipers are on. Modify byte 21 in the Central Electronics module.
Disable Rear Wiper: Disable the rear wiper completely by unchecking a specific bit in Byte 21 within the Central Electronics module.

Steering Wheel

Steering Wheel Push-to-Talk as Mute: Repurpose the push-to-talk button on your steering wheel as a mute button for the audio system. Modify byte 1 in the Steering Wheel module.

Instruments

Disable Seatbelt Warning: Disable the seatbelt warning chime and light. This modification involves adjusting byte 1 in the Instruments module.
Gauge Cluster Staging (Gauge Sweep): Enable a dramatic “sweep” of the gauges to their maximum values and back to zero when the ignition is turned on. Note: This feature does not work on all gauge clusters. Check your cluster’s part number for compatibility. This is activated through the “Staging” adaptation channel in the Instruments module.

Mirrors

Mirror Adjust Menu in MFA (2011+): Add a menu to the MFI for adjusting your mirrors individually or together. This applies to 2011 and later models and involves modifying byte 8 in the Central Electronics module.
Extend Mirror and Rear Window Heater Time: Increase the duration of the mirror and rear window defroster activation. The default is usually 10 minutes. You can customize this time by changing the “Rear Window & Outside Mirror Heater Activation Time” in the Central Electronics module’s Adaptation channels. The formula for calculating the new value is: New Value x 40 = Seconds Active.

Seats

Driver Seat Heater Memory: Enable the driver’s seat heater to remember and automatically resume its last setting (Off, 1, 2, 3) when the car is started. Modify the “Storage of driver seat heater level” setting in the Auto HVAC module’s Adaptation channels.
Passenger Seat Heater Memory (2012 Only): Enable the passenger seat heater to remember and resume its last setting. This feature is available for 2012 and later models and involves changing the “Storage of passenger seat heater level” setting in the Auto HVAC module’s Adaptation channels.

VCDS Tweaks for Performance and Handling

Tires

Disable TPMS: Disable the Tire Pressure Monitoring System (TPMS) for those using winter wheels or aftermarket wheels without TPMS sensors. Modify byte 8 in the Central Electronics module. More details on TPMS management can be found here: TPMS Activation and Reset

Drivetrain and Chassis

Electronic Differential Lock (XDS) Strength: Adjust the aggressiveness of the XDS system, which electronically simulates a limited-slip differential by applying brake pressure to the inside wheel during hard cornering. Higher values result in more aggressive intervention. Adjust the “Electronic Differential Lock (XDS)” setting in the ABS module’s Adaptation channels. The stock setting for the GTI is 0, while higher performance models like the Scirocco R use a setting of 2.
Brake Assist: Modify the sensitivity of the brake assist system, which reduces the amount of pedal pressure required for hard braking. Adjust the “Brake Assist” setting in the ABS module’s Adaptation channels.
Driver Steering Recommendation (DSR): Adjust the sensitivity of the Driver Steering Recommendation system, which provides a subtle steering “nudge” to help correct the car’s trajectory during a skid. There are three settings: strong (stock), center, and weak. Modify the “DSR” setting in the ABS module’s Adaptation channels.
Torque Steer Compensation (TSC): Activate or adjust the Torque Steer Compensation system, which helps mitigate torque steer in front-wheel-drive models by using the steering assist system. Modify the “Torque Steer Compensation (TSC)” setting in the Steering Assist module’s Adaptation channels. Torque Steer Compensation Discussion

Safety Systems

Disable ESP: Warning: Disabling the Electronic Stability Program (ESP) is not recommended and can be dangerous. However, if you choose to do so, it can be accomplished by modifying Channel 09 in the Steering Assist module’s Adaptation channels. ESP Disable Discussion
Hill Hold Control: Adjust the behavior of the Hill Hold Control (HHC) system, which automatically applies the brakes on a hill to prevent rollback. You can adjust when the brakes release (normal, early, late) or disable HHC completely. Modifying the HHC setting is done through the “Hill Hold Control (HHC)” adaptation channel in the ABS module. To disable HHC completely, uncheck a specific bit in Byte 16 of the ABS Brakes Long Coding Helper.

Service Intervals

Adjusting Service Intervals: Customize the service interval reminders displayed in the instrument cluster. This allows you to align the reminders with your preferred maintenance schedule. Adjust the “SIA – maximum value of time to service” or “SIA – maximum value of distance to service” settings in the Instruments module’s Adaptation channels.
