Frequently Asked Questions (FAQ)

Welcome to the OBD PRO FAQ page! Here you’ll find answers to the most common questions our customers ask. If you don’t find what you’re looking for, feel free to contact us via Instagram @obd_pro_mk or email us directly.

🔧 What services do you offer?

We specialise in:

  • Vehicle coding & software tweaks

  • Unlocking hidden factory features

  • Diagnostics & fault code clearing

  • Mileage blocker installation (for dyno & track use only)

  • ECU/TCU updates and performance adjustments

🚗 What is vehicle coding?

Vehicle coding is the process of unlocking or modifying software features already built into your car’s system by the manufacturer. This can include things like:

  • Activating hidden menus

  • Enabling comfort functions (e.g. windows via remote)

  • Display customisation

  • Apple CarPlay/Android Auto activation

  • And much more!

🔐 Are these features safe to unlock?

Yes. All features we unlock are OEM (original equipment manufacturer) features already programmed into your car. We simply make them available. We follow strict procedures to ensure your vehicle’s safety and integrity is never compromised.

📍 Where are you based?

We are based in the UK and primarily operate around Milton Keynes, but we may offer mobile services in surrounding areas or support remote coding where applicable.

⏱ How long does the coding process take?

Most coding services are completed within 30 minutes to 1 hour. More advanced coding or diagnostics may take longer. We aim to complete all jobs within 24 hours, and if parts are needed, work is completed the same day they arrive.

🧩 What if my car needs parts?

If your vehicle requires additional parts for the service:

  • We will order the parts on your behalf

  • Delivery typically takes 2–3 working days

  • Once received, the installation or service is completed same-day

💳 How do I pay?

We accept payments via:

  • Cash (in person)

  • Bank transfer

  • Card payments (subject to availability)

  • Online payment links (sent directly to your phone/email)

💰 Do you offer refunds?

As a service-based business, we do not offer refunds unless:

  • We are unable to deliver the service purchased

  • The required product is out of stock or unavailable

However, we do offer a "Buy Back" service for mileage blockers that have been fitted and removed by us, which may be eligible for return at trade price, subject to discretion.

More details are in our Refund Policy.

🏁 Are mileage blockers legal?

Mileage blockers are strictly for dyno testing or track use only.
It is illegal to use them on public roads for the purpose of odometer fraud.
By purchasing a mileage blocker, you agree to use it responsibly and in compliance with all applicable laws.

📱 How can I book a service?
