This guide provides a comprehensive overview of VCDS coding for the Volkswagen Passat B5.5. We’ll cover various modules and common coding procedures. Ross-Tech is not responsible for any damage resulting from these instructions. Use them at your own risk.
Engine Module (01 – Engine)
The Engine module allows for adjustments to idle speed and throttle body adaptation, as well as activation of certain features like cruise control.
Idle Speed Adaptation
Note: Consult your repair manual for specific instructions.
With the engine warmed up and idling:
- Select: 01 – Engine
- Adaptation – 10:
- Channel 01: Enter an adaptation value between 124 and 132.
- Save:
Throttle Body Adaptation
Important: Do not touch the accelerator and ensure the engine is OFF.
- Turn the key ON, but do NOT start the engine.
- Select: 01 – Engine
- Measuring Blocks – 08: Group 060 or Group 98.
- Go!
- Switch to Basic Settings: Observe “ADP RUN” in the display. The adaptation process begins automatically. Values will change, and you’ll hear the throttle body cycle.
- Leave in Basic Settings for approximately 30 seconds.
- Switch back to Normal Settings: Adaptation is complete.
Activating Cruise Control (DBW)
New ECUs often have cruise control deactivated. To activate:
- Select: 01 – Engine
- Login – 11:
- Enter Code: 11463
- Do It!
CAN Gateway Coding (19 – CAN Gateway)
The CAN Gateway module, located in the instrument cluster, controls CAN-BUS communication. Its coding determines which modules are available on the network. The last digit of the coding represents the sum of the following options:
- 0: No available equipment
- +1: Automatic Transmission
- +2: ABS Brakes
- +4: Airbags
For example, to enable Automatic Transmission, ABS Brakes, and Airbags, add 1 + 2 + 4 = 7. The coding would be 00007.
Central Convenience (46 – Central Convenience / 35 – Central Locking)
This module controls various convenience features, primarily on vehicles with power windows (module 46) or manual windows (module 35).
Selective Unlocking
- Select: 46 – Cent. Conv. (or 35 – Cent. Locking)
- Recode – 07: Note the existing coding.
- Enter 5-digit Code: Refer to your vehicle’s documentation for the correct coding. Modifying the last digit (odd for selective unlock, even for all doors unlocking simultaneously) changes the unlocking behavior. Adding 1 to the last digit typically changes from single door to all door unlock.
- Do It!
Lock/Unlock Horn/Flash Confirmation
- Select: 46 – Cent. Conv. (or 35 – Cent. Locking)
- Adaptation – 10:
- Select Channel:
- Channel 03: Auto Lock
- Channel 04: Auto Unlock
- Channel 05: Unlock Horn Confirmation (1 = On, 0 = Off)
- Channel 06: Lock Horn Confirmation (1 = On, 0 = Off)
- Channel 07: Unlock Turn Signal Confirmation (1 = On, 0 = Off)
- Channel 08: Lock Turn Signal Confirmation (1 = On, 0 = Off)
- Enter Adaptation Value: (1 = On, 0 = Off)
- Save:
Radio Recoding (56 – Radio)
- Select: 56 – Radio
- Recode – 07: Note existing coding.
- Enter 5-digit Code: Determined by sound system options (see below).
- Do It!
Coding Breakdown:
- Digits 1-2: Sound Field Tuning (00 – Premium IV/V, 04 – Monsoon)
- Digit 3: Speaker System (0 – Premium V/VI Monsoon, 4 – Premium IV/V/VI Non-Monsoon)
- Digit 4: Sound Correction (0 – Premium IV/V Non-Monsoon, 4 – Premium V Monsoon)
- Digit 5: CD Player/Changer (1 – Without, 3 – With, 5 – Without with Display, 7 – With with Display)
For a Passat with Monsoon and a CD changer, the code would be 04043.
