VCDS (Vag-Com Diagnostic System) offers a powerful way to customize your Volkswagen, Audi, Seat, or Skoda vehicle. This involves modifying the software within various control modules to enable or disable features, often referred to as “Vcds Coding Options.” This article delves into understanding and applying these coding options, specifically focusing on interpreting the structure of the coding string.
Deciphering the Coding Structure
VCDS coding often appears as a string of hexadecimal digits, where each digit or group of digits corresponds to a specific feature or setting. Let’s break down a typical example:
????xxx: Options
+0001 = Quattro (Standard)
+0002 = w/o Driver Information System (DIS)
+0004 = Vehicle with Clutch (NO Automatic)
+0008 = Second Tire Size Pair
+0016 = Tire Pressure Monitoring
+0032 = Adaptive Air Suspension
+0064 = Advanced Frontlighting System (AFS)
+0128 = Adaptive Cruse Control (ACC)
+0256 = 70-Liter Fuel Tank (only Front-Wheel-Drive)
+2048 = Switch Option for Bord Computer Levels (MY 2006+)
xxxx?xx: Country
0 = Germany
1 = Rest of World (Left-Hand-Drive)
2 = USA
3 = Canada
4 = Great Britain
5 = Japan (Left-Hand-Drive)
6 = Arabian States
7 = Australia
8 = Rest of World (Right-Hand-Drive)
9 = Japan (Right-Hand-Drive)
xxxxx?x: Seatbelt Warning (3-6 = MY 2005+ only)
0 = No Seatbelt Warning
1 = Seatbelt Warning (EU-NCAP)
2 = Seatbelt Warning (NAR Old)
3 = Seatbelt Warning (NAR New)
4 = Seatbelt Warning (EU-NCAP incl. Passenger)
5 = Seatbelt warning (NAR Old incl. Passenger)
6 = Seatbelt Warning (NAR New incl. Passenger)
xxxxxx?: Illumination
0 = Needles OFF and Scales OFF (Term. 15 ON / Term. 58 OFF)
1 = Needles ON and Scales OFF (Term. 15 ON / Term. 58 OFF)
2 = Needles OFF and Scales ON (Term. 15 ON / Term. 58 OFF)
3 = Needles ON and Scales ON (Term. 15 ON / Term. 58 OFF)
In this example:
- “?” represents a digit that contributes to a specific function. For instance, the first four digits (????) define various vehicle options.
- “x” denotes a digit that should remain unchanged.
- “+” indicates that values should be added together. Each option has a unique numerical value assigned to it. If your vehicle has multiple options, you add their corresponding values.
Calculating Combined Values
Let’s say your car has Quattro (0001), a manual transmission (0004), and Adaptive Cruise Control (0128). To determine the correct coding for the first four digits, you would sum these values: 0001 + 0004 + 0128 = 0133. Therefore, the first four digits of your coding string would be 0133. The remaining digits would be determined based on your vehicle’s specific configuration for country, seatbelt warning, and illumination.
Applying VCDS Coding Options
Remember, incorrect coding can potentially lead to malfunctions or errors. Always consult reputable resources, such as the official Ross-Tech Wiki (http://wiki.ross-tech.com/), for accurate coding information specific to your vehicle’s model and year. This ensures you’re applying the correct modifications safely and effectively.
Conclusion
Understanding the structure of VCDS coding strings is crucial for successful customization. By carefully interpreting the meaning of each digit and applying the correct calculations, you can unlock a range of hidden features and personalize your driving experience. Always prioritize safety and consult reliable sources before making any coding changes.
