Mobile App

Terms and Conditions

Last updated 19 October 2026

These terms apply to the Haldex.Flash mobile app, the licences you use with it and the tune files it delivers. By creating an account, buying a licence or using the app you agree to them. If you do not agree, please do not use the app.

The three things to know before you start:

  • A licence is tied to one vehicle permanently once you assign it. It cannot be moved to another vehicle or another person.
  • A licence can be refunded within 14 days of purchase only while it is unassigned. Once assigned it is non-refundable.
  • Flashing rewrites a drivetrain control unit. You do it at your own risk, and it may affect your warranty, insurance and road legality.

1. Who we are

The app and the service behind it are provided by Road Rage Performance Ltd ("we", "us"), a company registered in England and Wales with company number 10542607. Registered office: Unit D5 D6 Forstal Business Park, Paddock Wood, Tonbridge, England, TN12 6PY.

You can contact us at info@roadrageperformance.co.uk.

2. What the app does

The app connects to a compatible OBD adapter over Bluetooth and lets you read, flash, monitor and live-tune the Haldex all-wheel-drive control unit or VAQ electronic differential control unit on supported Volkswagen Audi Group vehicles.

It is intended for enthusiasts and professionals who understand vehicle tuning. It is not a diagnostic or repair tool, and it will not fix a mechanical fault.

3. The app, licences and adapter are separate

Downloading the app does not entitle you to a licence or an adapter, and buying one does not include the other.

4. Your account

5. Licences are locked to one vehicle

When you assign a licence in the app, it is bound to that vehicle's VIN for good. The app warns you before you confirm. After that:

Check the VIN shown in the app carefully before you confirm. We cannot undo an assignment made to the wrong vehicle.

A licence gives you a personal, non-exclusive right to use our software and tune files on the assigned vehicle. We keep all ownership and intellectual property rights in them.

6. Refunds and cancellation

None of this affects your legal rights if what we supply is faulty or not as described.

7. Risks of flashing

Flashing rewrites the software on a control unit that manages your vehicle's drivetrain. By using the app you accept that:

You use the app, and apply any tune, entirely at your own discretion and risk.

8. Before you flash, and afterwards

You are responsible for making sure that:

A tuned system needs looking after. We recommend a full Haldex service, including fluid and filter and an inspection of the pump, every 10,000 miles. We are not liable for problems that come from poor maintenance.

9. Road legality

Rules on vehicle modification differ from country to country. It is your responsibility to make sure that a modified vehicle is legal to use on the road where you drive it, that it meets any inspection or type-approval requirements, and that live tuning features are used safely and lawfully. Do not operate the app while driving.

10. Custom tune files

Where the app lets you load a tune file that you, a dealer or anyone else has supplied, that file is not ours. We have not created, tested or approved it, and we accept no responsibility for what it does to your vehicle. You load custom files entirely at your own risk, and you must have the right to use any file you load.

11. What you must not do

12. Support and diagnostic reports

We offer support for installing and using the app. To help us investigate a problem you can choose to send a diagnostic report from the app. What a report contains and how we handle it is described in our Privacy Policy.

13. Updates and availability

We may update the app from time to time, including through over-the-air updates that install without a visit to the app store. Some updates may be required before the app will keep working. We aim to keep the service available but do not promise that it will be uninterrupted or error-free, and flashing needs a working internet connection for licence checks.

14. Our liability

Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot be limited or excluded by law. If you are a consumer, your statutory rights are not affected.

Subject to that, and to the fullest extent the law allows:

15. Closing your account

You can delete your account at any time from within the app or by emailing us. A licence already assigned to a vehicle stays with that vehicle, but you will no longer be able to manage it from the deleted account. Unused licences are lost when the account is deleted, so ask for any refund you are entitled to first. The Privacy Policy explains what happens to your data.

16. Changes to these terms

We may update these terms. The date at the top shows when they last changed. If a change is significant we will tell you in the app or by email before it takes effect.

17. Governing law

These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction. If you are a consumer living elsewhere in the UK you can also bring a claim in the courts where you live.
