OD is an abbreviation for the Latin term oculus dexter which means right eye. Notice that the right eye information is asked for first even though we typically read from left to right.
OS is an abbreviation of the Latin oculus sinister which means left eye. That will be referenced on the far right column of the prescription.
SPH is short for sphere. The sphere of your prescription indicates the power on the lenses that is needed to see clearly. A plus (+) symbol indicates the eyeglass wearer is farsighted. A minus (-) symbol indicates that the eyeglass wearer is nearsighted.
CYL is short for cylinder. The cylinder indicates the lens power necessary to correct astigmatism. If the column has no value (is blank), it indicates that the eyeglass wearer does not have astigmatism. If this is the case on your prescription, you can leave it blank when entering it in.
AXIS is a prescription will include an axis value for those with astigmatism. This number represents the angle of the lens that shouldn't feature a cylinder power to help correct your astigmatism.
ADD is short for "additional correction." This is where details about bifocals, multifocal lenses or progressive lenses would appear.

This version, often used with a standard KKL (K-Line) cable, allows for deep-level communication with the vehicle's instrument clusters and ECUs without needing to desolder chips. Key Features of Version 1.20
Immobilizer Login Retrieval: Quickly extract the 4-digit or 5-digit PIN (Secret Key Code) needed for key programming or matching new clusters.
Mileage Correction: Adjust odometer readings for instrument cluster replacements (strictly for legal/educational use).
EEPROM Reading & Writing: Direct access to read, edit, and save the binary data of VAG control units for backups or cloning.
Airbag Crash Data Reset: Capability to clear crash data or SRS errors after a deployment or repair.
Error Code Management: Read and clear manufacturer-specific diagnostic trouble codes (DTCs) across multiple modules. Compatibility and Hardware Requirements
The V1.20 software is highly compatible with older VAG vehicles, typically those manufactured between 1997 and 2003/2004. Go to product viewer dialog for this item.

Mastering Your VAG Instrument Cluster: A Guide to VAG EEPROM Programmer v1.19/v1.20
If you are a Volkswagen, Audi, Seat, or Skoda enthusiast who enjoys DIY maintenance or retrofitting, the VAG EEPROM Programmer is a legendary tool in the community. Often searched as "VAG EEPROM Programmer v1.20," it is essential for reading and writing data directly from your vehicle's instrument cluster (dashboard) and engine control unit (ECU).
This article explores what this software does, how to use it safely, and what you need to get started. What is VAG EEPROM Programmer?
VAG EEPROM Programmer is a lightweight, Windows-based utility designed to communicate with older VAG vehicles (typically from the late 90s to the mid-2000s) via the OBD-II port.
While many users look for a "v1.20" version, v1.19 is the most stable and widely recognized "top" version used by professionals and hobbyists alike. It allows you to access the "brains" of your car's electronics to perform tasks that standard diagnostic tools (like basic OBD scanners) cannot. Key Features & Capabilities
Reading Login/PIN Codes: If you need to program a new key using VCDS, you first need the 4 or 5-digit Secret Key Code (SKC). This tool can extract that PIN from the Immobilizer.
Mileage Calibration: If you replace a broken instrument cluster with a used one, you can use this tool to sync the odometer to the car's actual mileage.
EEPROM Backup: Before making any electronic changes, you can save a full "dump" (backup) of your cluster's memory. This is a lifesaver if something goes wrong.
Immo Status Management: You can read the status of the Immobilizer or even "deactivate" it in certain ECU types (for off-road or engine swap purposes).
Fault Code Clearing: It includes basic functions to read and clear airbag and engine error codes. Hardware Requirements: The KKL Cable
To use VAG EEPROM Programmer, you cannot use a standard "hex-can" VCDS cable. Instead, you need a simple USB KKL (K-Line) Interface. These are inexpensive and widely available online.
Pro Tip: Ensure your cable uses the FTDI FT232RL chip for the best compatibility with Windows 10 and 11. How to Use VAG EEPROM Programmer Safely
Setup: Connect your KKL cable to your laptop and the car’s OBD port. Turn the ignition to the "ON" position (engine off).
COM Port: Open Device Manager on your PC and ensure your cable is set to a port between COM1 and COM4. In the software, select the matching port. Applications of VAG EEPROM Programmer V120:
Read First: Always click "Read EEPROM" before doing anything else. Once the hex data appears, go to File > Save to keep a backup.
Write Carefully: Only use the "Write" functions if you are certain of the changes you’ve made. Writing a corrupt file can "brick" your instrument cluster, preventing the car from starting. Common Compatible Vehicles
This tool works best on K-Line vehicles (approx. 1998–2005), including: VW: Golf MK4, Bora, Jetta, Passat B5/B5.5, Polo 6N/9N. Audi: A3/S3 (8L), A4 (B5/B6), A6 (C5), TT (8N). Seat: Leon 1M, Ibiza, Toledo. Skoda: Octavia MK1, Fabia MK1. Conclusion
VAG EEPROM Programmer remains a "top" download for VAG owners because it provides dealer-level access to immobilizer data for the cost of a basic cable. Whether you are swapping a cluster or just retrieving a lost PIN, it is a must-have in your digital toolbox.
Disclaimer: Modifying vehicle EEPROM data can be risky. Always keep backups and ensure your laptop battery is charged during the process.
If you are looking to enhance VAG EEPROM Programmer v1.20 , a highly useful feature would be Automated Diagnostic Recovery (ADR) The Feature: Automated Diagnostic Recovery (ADR)
One of the most common issues with v1.20 is the "No ECU Found" or "RX-Timeout" error, particularly when running on Windows 10/11 or using modern high-speed USB interfaces
. Currently, users have to manually "fiddle" with Windows Data Execution Prevention (DEP) or timing settings to get a stable connection How ADR would work: Auto-Latency Tuning
: The software would automatically ping the K-Line and adjust the Virtual COM Port (VCP) latency timer (e.g., between 2ms and 13ms) until a stable handshake is achieved Voltage Monitoring
: It would provide a real-time battery voltage readout, warning the user if the voltage drops below the 13.5V–14V threshold often required for successful EEPROM writing One-Click "Safe Mode"
: A pre-configured profile that automatically whitelists the application in Windows DEP and sets compatibility mode to Windows XP/7 to prevent mid-write crashes Existing Features in v1.20
For reference, current versions already include several core capabilities for older VAG vehicles (roughly 1997–2003) like the Golf Mk4, Passat B5, and Audi A4 B5 Immobilizer Login Extraction
: Reads the 4-digit SKC (Secret Key Code) directly from the cluster for key programming Mileage Correction
: Allows for odometer adjustment on supported VDO and Motometer clusters Airbag Reset
: Clears hard-fault "Crash Data" from SRS modules that standard OBD tools often cannot reach Binary Dump Handling : Supports reading, saving, and writing full EEPROM files for module cloning Compatibility Note This software is designed specifically for communication. It works best with inexpensive FTDI-based VAG-COM 409.1 . It is generally not compatible
with newer CAN-bus vehicles (Golf Mk5/6/7, Passat B6+) or high-end VCDS (Ross-Tech) hex-can cables
