Will the Porsche PIWIS4 Diagnostic Tool Kit work with my specific Porsche model, including the latest 2025 vehicles?

Yes! The Porsche PIWIS4 Diagnostic Tool Kit from KKS Supercar is fully compatible with all Porsche models up to the 2025 model year, including Cayenne, Panamera, Macan, 911, Taycan, and more. This means you can confidently use it for both older and the very latest Porsche vehicles in your garage or workshop.

What are the differences between the PT4G Device Only, PT4G + Software SSD, and Complete Kit with Laptop configurations?

Great question! Choosing the right configuration depends on your needs: - PT4G Device Only: Includes just the professional-grade diagnostic unit. Perfect if you already have compatible software and a laptop. - PT4G + Software SSD: Comes with the device and a pre-installed software SSD. Just plug the SSD into your own laptop (must meet minimum requirements) and you're ready to start diagnosing. - Complete Kit with Laptop: A turnkey solution—includes the PT4G device, software SSD, plus a fully setup laptop. Ideal for hassle-free setup and immediate use. All kits support offline diagnostics, Porsche model coverage up to 2025, and dual Wi-Fi/USB connectivity.

Are updates and after-sales support included with the Porsche PIWIS4 Diagnostic Tool Kit?

Absolutely! Your purchase includes free software updates to ensure ongoing compatibility with the latest Porsche models. Each kit comes with a warranty and is backed by the KKS Supercar technical team, who offer remote programming and after-sales support. Offline diagnostic functions are included, and you'll only need a personal Porsche online account for certain online-exclusive features. There are no hidden update costs, so you can focus on diagnostics with complete peace of mind.

Configure a PIWIS diagnostic package for supported Porsche vehicles

This listing offers PT3G interface, PT4G interface, software-only and complete laptop configurations for supported Porsche diagnostic work. Available functions depend on the vehicle, software build, interface generation and account authorization. Porsche online credentials and server access are not included unless explicitly stated.

Compare the four available configurations

Shopify variant	Included	Before ordering
Complete set	Configured laptop, selected PIWIS software and PT4G VCI	Confirm laptop model, condition, software build and required Porsche coverage
PT4G VCI	PT4G diagnostic interface only	Requires compatible computer, software, cables and any necessary account access
PT3G VCI	PT3G diagnostic interface only	Confirm that the vehicle, software generation and intended task support PT3G
PIWIS 3 and 4 software SSD	Software SSD only	Requires compatible laptop, interface and any required authorization

Offline and online-authorized functions

Compatible offline configurations can support vehicle identification, fault reading and clearing, live data, selected tests, service functions and other software-dependent procedures. Coding, programming, component activation, security access, software downloads and protected functions can require a valid Porsche account, online connection and permissions.

Not included: Do not assume that a Porsche online account, PPN access, security credentials, server authorization or an ongoing manufacturer subscription is included with any package.

PT3G compared with PT4G

PT4G is the newer interface generation and is the starting point for compatible newer Porsche applications. PT3G can remain useful for supported earlier vehicles and software environments. Interface generation alone does not guarantee coverage: confirm the Porsche model, model year, software build and exact task before ordering.

Vehicle coverage

Coverage varies across Porsche platforms, model years, control units and software releases. Newer electric vehicles and protected functions can have additional hardware, software and authorization requirements. Send KKS the vehicle details and required procedure for confirmation.

Laptop, updates and support

The complete-set variant includes a configured laptop; interface-only and software-only variants do not. Confirm the laptop model and condition before dispatch. Software versions and update arrangements change over time, so the current build and any included update period should be confirmed on the order.
