At Miltech Auto Performance, we’re proud to be part of the Porsche Partner Network (PPN) — a recognised programme that allows selected independent specialists to access official Porsche technical systems, tools and data.

For Porsche owners, this means you can benefit from the expertise and personal service of an independent specialist while still maintaining the same level of diagnostic capability and technical accuracy you would expect from a main dealer.

Porsche PIWIS – The Official Diagnostic System

Modern Porsche vehicles are incredibly advanced machines, with dozens of interconnected control units managing everything from engine performance and suspension systems to driver assistance features and comfort electronics.

To communicate properly with these systems, technicians need the official Porsche diagnostic platform — PIWIS (Porsche Integrated Workshop Information System).

At Miltech, we use the genuine Porsche PIWIS diagnostic system, which allows us to:

• Communicate directly with all vehicle control units
• Read and interpret Porsche-specific fault codes
• Perform guided diagnostics and troubleshooting
• Carry out software coding and adaptations where required
• Access official Porsche repair procedures and technical bulletins

Using the correct diagnostic equipment is critical when working on modern Porsche vehicles, ensuring that issues are diagnosed accurately and repairs are completed to manufacturer standards.

Recording Your Service on the Porsche Database

Another key advantage of working with a Porsche Partner Network workshop is the ability to register service work on the official Porsche digital service record system.

After servicing your vehicle, we can record the service directly on the Porsche central database, meaning:

• Your car’s maintenance history is securely stored
• Future owners can verify the service record
• The vehicle maintains a documented Porsche service history
• It helps protect long-term resale value

For many owners, maintaining a verifiable service history is extremely important, particularly for vehicles that may eventually be sold or collected.

Independent Expertise With Dealer-Level Technology

Being independent allows us to offer a more personal, flexible approach than main dealerships. We take the time to get to know our customers and their cars, often looking after vehicles for many years across multiple ownership cycles.

At the same time, our Porsche Partner Network accreditation and PIWIS diagnostic capability ensure we can work to the same technical standards expected of a Porsche specialist.

This combination of manufacturer-level tools and independent expertise is why many Porsche owners across Ringwood, Wimborne, the New Forest and Dorset choose Miltech for servicing, maintenance and performance upgrades.
