Porsche Specialists

Miltech Auto Performance is an independent Porsche specialist located near the New Forest, ideally positioned between Ringwood, Hampshire and Wimborne, Dorset.

We support Porsche owners across Dorset, Hampshire and the surrounding areas, providing expert servicing, diagnostics and maintenance across multiple Porsche generations and models.

As a Porsche Partner Network (PPN) accredited workshop, we are authorised to access official factory technical data and operate the genuine Porsche PIWIS diagnostic system. This allows us to carry out diagnostics, coding, programming and repairs to manufacturer standards — delivering dealer-level technical capability with the flexibility, transparency and personal service of an independent specialist.

Our Porsche Services

As a Porsche Partner Network (PPN) accredited workshop, we offer a comprehensive range of Porsche services, including:

  • Porsche diagnostics and fault finding (PIWIS-based)

  • General inspections and health checks

  • Pre-purchase inspections (PPI)

  • Porsche servicing

  • Brake and clutch replacement

  • Suspension, geometry, and setup

  • Upgrades and modifications

  • Ongoing maintenance and preventative care

Every service is carried out with a focus on correct diagnosis, quality workmanship, and long-term reliability… not guesswork or unnecessary work.

Specialist Knowledge.
Approachable Service.

Our team is genuinely passionate about Porsche ownership and understands that trust and communication matter just as much as technical ability. We take the time to explain findings clearly, answer questions honestly, and help you make informed decisions about your car.

In addition, Miltech Auto Performance is approved by Design 911 as a Porsche Expert Service Centre.

This recognition reflects our:

  • Porsche-specific technical knowledge

  • Correct installation practices

  • Use of approved parts and procedures

  • Commitment to high standards of workmanship

It also gives our customers confidence that their Porsche is being maintained and upgraded by a workshop trusted within the Porsche specialist network.

Fully Equipped Porsche Specialist Workshop

All work is carried out in our fully equipped workshop in Three Legged Cross, just one mile from Moors Valley Country Park. We invest heavily in the correct tools, systems, and processes required to work on Porsche vehicles properly.

This includes:

  • Porsche PIWIS diagnostics (Porsche’s official diagnostic system)

  • Model-specific specialist tools

  • Porsche-approved oils and parts

  • Accurate fault diagnosis and system analysis

Using PIWIS allows us to communicate directly with your Porsche’s control units, enabling accurate diagnostics, over-rev and operating-hour analysis, and correct system calibration — the same level of diagnostic access used by Porsche main dealers.
