 A modern, web-based diagnostic and reverse-engineering tool for the **Audi A4 B5 (1994-2001) Auto HVAC** (Climate Control) module over the vintage **KWP1281** protocol. Connect to your vehicle using a standard KKL (FTDI) diagnostic cable to read faults, stream live measurement blocks, and visualize sensor data on an interactive dashboard.

-### 🖥️ Modern Web Dashboard
+### Modern Web Dashboard
 - **Glassmorphism UI:** A sleek, dark-themed automotive dashboard accessible directly via a web browser.
 - **Port Auto-Detection:** Automatically scans and connects to your KKL/FTDI serial port.
 
-### 📊 Live Data & Gauges
+### Live Data & Gauges
 - **Real-Time Arc Gauges:** Monitor vital systems like Compressor Status, System Voltage, and Cabin/Outside/Evaporator Temperatures.
 - **Live Data Monitor:** Stream sensor data using Server-Sent Events (SSE) with real-time sparkline charts.
 - **Measurement Blocks:** View raw and decoded sensor data across all 8 HVAC measurement groups utilizing 70+ VAG mathematical formulas.
 
-### 🗺️ Interactive Sensor Map
+### Interactive Sensor Map
 - **2D Car SVG Diagram:** See the exact physical location of every HVAC sensor (G17, G56, G65, G86, G89, G107, G263) and flap motor (V68, V70, V71, V85).
 - **Health Indicators:** Sensor dots dynamically change color (Cyan = Normal, Orange = Warning, Red Pulsing = Fault/Open Circuit, e.g., -49°C readings).
 
-### 🛠️ Diagnostics & Export
+### Diagnostics & Export
 - **Read & Clear Faults (DTCs):** Built-in database of HVAC-specific fault codes with detailed status elaborations (Active, Stored, Intermittent).
 - **Export to JSON:** Export full diagnostic reports (DTCs + Measurement Blocks) tailored for analysis by AI tools.

-## ⚠️ Safety Warning
+## Safety Warning
 
 > **CAUTION:** This tool communicates directly with vehicle electronics on the K-Line. While it is designed to be read-only (with explicit confirmation required for clearing faults), using incorrect or cheap counterfeit cables can potentially introduce noise on the K-Line or cause communication errors. Do not use this tool while the vehicle is in motion. Use at your own risk.
