The Volkswagen Tiguan offers a plethora of customization options through VCDS (Vag-Com Diagnostic System) coding. This guide focuses on unlocking hidden features in your Tiguan 2 using VCDS tweaks, specifically within Module 9 – Central Electronics, which controls many convenience features. This module offers a significant return on investment for your VCDS cable purchase from Ross-Tech.
Accessing Tiguan Convenience Settings via VCDS
Module 9 – Central Electronics houses 30 Bytes (0-29), each containing various Bits (checkboxes) that toggle features on or off. Accessing this module can be tricky. You might encounter a “no response from controller” error, even if other modules respond during the same session. This is a known issue, potentially caused by the module entering a sleep mode when the doors are locked.
To resolve this, lock and unlock your driver’s side door several times using the central locking button, ensuring the doors are unlocked for the final attempt.
Tiguan VCDS Coding Options: Byte by Byte
While a Ross-Tech Coding Manual for the Tiguan exists (VW Tiguan (5N) – Ross-Tech Wiki), it’s often incomplete and may reference coding for other VAG vehicles. Below are some key Bytes and Bits for customizing your Tiguan 2:
Auto Lock Rear Hatch
Enable or disable automatic locking of the rear hatch/boot.
Mirror Lowering on Reverse
Add the “Mirror Lowering on Reverse” option to your Multi-Function Display (MFD). Requires memory seat option (not available in all markets).
Alarm Beep on Lock/Unlock
Activate a beep sound from the alarm siren when locking or unlocking the doors. Requires factory-fitted alarm; the sound comes from the siren, not the horn.
Synchronized Mirror Adjustment
Enable or disable synchronized side mirror adjustment.
Daytime Running Lights (DRLs)
Configure various DRL options:
-
Low Beams as DRLs: Bit 2
-
Fog & Park Lights as DRLs: Bit 1 (Manually enter ‘1’ in the second to last digit of the Binary Code)
-
Fogs as Cornering Lights: Bit 7 (Activates the left or right fog light when turning the steering wheel or using the indicator)
Note: If no checkbox is present for a specific Bit, manually modify the Binary Code. ‘0’ represents ‘off,’ and ‘1’ represents ‘on.’ Remember, Bit 0 is the last character in the Binary code, Bit 1 the second to last, and so on (read from right to left). Additional DRL options are available in Byte 15 (e.g., Bit 6) for vehicles without bi-xenon headlights.
Comfort Turn Signal Blinking
-
Enable/Disable:
-
Change Number of Blinks (1-5): Access “Adaptation” and select “Channel 31.”
Coming/Leaving Home Lights
Enable or disable Coming Home and Leaving Home lighting features using Bits 5 and 6.
