What is the Difference Between the Porsche Diagnostic Tool PIWIS 4 and PIWIS 3

The Porsche diagnostic tools, PIWIS 3 and PIWIS 4, are essential for servicing and diagnosing Porsche vehicles. With the release of PIWIS 4, many technicians and service centers are curious about the differences between these two diagnostic systems. Here’s a detailed comparison highlighting the advancements and key differences.

Key Differences Between PIWIS 4 and PIWIS 3

1. Compatibility with Vehicle Models

• PIWIS 3: This tool supports Porsche vehicles up to the 2020 model year. While it works reliably for many models, its compatibility with newer vehicles is limited.
• PIWIS 4: In contrast, PIWIS 4 supports a wider range of vehicles, including all models up to 2024. This extensive compatibility is crucial for dealerships and service centers that service the latest Porsche models, including new electric vehicle models.

2. Advanced Diagnostic Capabilities

• PIWIS 3: While it provides advanced diagnostic capabilities such as retrieving diagnostic trouble codes (DTCs), viewing live data, and performing component tests, it lacks some modern features found in newer technology.
• PIWIS 4: Enhancements in PIWIS 4 offer improved diagnostic capabilities and programming functionalities, allowing technicians to interface with more recent electronic architectures and obtain more detailed vehicle data than PIWIS 3.

3. SFD Diagnostic Protection

One of the standout features of PIWIS 4 is its SFD (Secure Data Access) Diagnostic Protection. This technology enhances protection against unauthorized access to vehicle systems, ensuring both efficiency and security during vehicle servicing. SFD support is not available in PIWIS 3, making PIWIS 4 a more secure option for dealerships.

4. Wireless Connectivity Options

• PIWIS 3: Some versions offer limited wireless connectivity, which provides some flexibility in diagnostics but may require wired connections for certain tasks.
• PIWIS 4: This model introduces expanded wireless connectivity options, allowing technicians to perform diagnostics with greater convenience and less restriction during service operations.

5. Performance and Speed

PIWIS 4 is designed with enhancements that allow for faster performance and improved efficiency compared to its predecessor. Technicians can diagnose and service vehicles more quickly, which can lead to improved customer satisfaction and increased productivity in service centers.
