Terms of service
The deal between you and Mobile Flash Solutions Ltd when you flash your own car with our software.
- You must be 18 or over and own the car, or have the owner's permission.
- Tuning can affect your warranty, your insurance and your car's road-legal status. Tell your insurer.
- A tune licence covers one vehicle, identified by VIN, and is not transferable.
- Nothing here removes the rights you have as a consumer under UK law.
These terms
These terms are the agreement between you and Mobile Flash Solutions Ltd, a company registered in England and Wales with company number 15604123, at 5d Folgate Road, North Walsham, England, NR28 0AJ. In these terms "we", "us" and "our" mean that company, and "you" means the person using MFS Connect.
By creating an account, or by using the MFS Connect app or the MFS OBD adapter, you accept these terms. If you do not accept them, do not use the app. We recommend keeping a copy; we will always publish the current version on this page.
What the words mean
Who can use it
You must be 18 or over. You must own the vehicle, or have the owner's express permission to modify it. Flashing a vehicle you do not have the right to modify is your responsibility and not ours, and we may suspend an account we believe is being used that way.
Your account
You are responsible for keeping your login details private and for everything done through your account. Tell us promptly if you think someone else has access to it.
Give us accurate details and keep them current — particularly your email address, because that is how we reach you about a licence, a receipt or a safety notice.
The adapter
The adapter is sold to you as goods. Under the Consumer Rights Act 2015 it must be of satisfactory quality, fit for purpose and as described. If it is not, you have statutory rights to a repair, replacement or refund, and nothing in these terms limits them.
The adapter is designed to work with the app and supported vehicles only. Using it with other software, or opening or modifying it, may stop it working and is not covered by our warranty.
Licences, not ownership
When you buy a tune you are granted a personal, non-exclusive, non-transferable licence to use that tune on one vehicle, identified by VIN. You do not own the software and you do not acquire any rights in it beyond that use.
A licence cannot be moved to another vehicle or another account unless we agree in writing. If you sell the car, the licence does not automatically travel with it; contact us and we will tell you what is possible for that platform.
We may issue a revised version of a tune — to fix a fault, to improve it, or because a manufacturer software update requires it. Revisions to a tune you already hold are provided at no extra cost.
Supported vehicles
The app reads, writes and logs the engine control unit in supported VW Group vehicles through the adapter. Which functions are available depends on your specific ECU. We publish the supported control units on this site and in the app, and that list changes as platforms pass testing. A vehicle appearing on the list is not a promise that every feature is available for it; the app tells you what your car actually supports once it has read the ECU.
Your side of a safe flash
Writing to an ECU is a real operation on real hardware. The app checks what it can — battery voltage, connection quality, ECU identity — and will refuse to start if something is obviously wrong. Three things remain on you.
If a write is interrupted, stop and contact us before trying anything else. In most cases the ECU can be recovered by rewriting the original manufacturer software for it, and we will help you do it.
Warranty, insurance and road legality
Because every MFS tune is reversible, many owners flash back to stock before a dealer visit. A manufacturer may still be able to tell that the software was changed, and we make no promise that a tune is undetectable.
You are responsible for whether a modification is lawful where you drive. In the UK, changes affecting emissions control can make a vehicle fail its MOT or become illegal for road use. Rules differ in every country and we cannot advise on yours.
We would rather tell you all of this plainly than bury it.
What you must not do
- Extract, decompile, reverse engineer, copy, share, publish or resell any ECU file, calibration, or part of the app.
- Circumvent the VIN locking, the licence checks, or the encryption on a dealer's file.
- Use the service to defeat or remove emissions control equipment where that is unlawful.
- Flash vehicles commercially, or on behalf of others for payment, without a written dealer agreement with us.
- Interfere with the service, probe it for vulnerabilities without our written permission, or use it to harm anyone.
- Misrepresent whose tune a file is, or pass our work off as your own.
We may suspend or close an account that does any of these, and may keep evidence of it for as long as a claim could be brought.
Tunes supplied by other companies
Some tunes in the app are produced by independent tuning companies who distribute through us. Where that is the case the app names the tuner, and your licence is to use their file under these terms.
The tuner is responsible for the content and calibration of their own file. We are responsible for the app, the adapter, the flashing process, and for delivering the file to you intact. If something about a third-party tune is not right, tell us and we will take it up with the tuner; your statutory rights are against us as the seller.
Intellectual property
The app, the adapter firmware, our tunes, and everything on this site remain the property of Mobile Flash Solutions Ltd or our licensors. Nothing in these terms transfers any of it to you. Logs you record from your own vehicle are yours; you grant us permission to use them to provide support and to improve the product, in a form that does not identify you.
Price and payment
Prices are shown in the app before you buy and include VAT where it applies. Payment is taken by our payment provider at the time of purchase. If a price is obviously wrong — a listing error — we may cancel the order and refund you in full rather than hold you to it, and we will tell you promptly.
Cancelling and refunds
If you buy as a consumer you normally have 14 days to change your mind about digital content. Because a tune is usable the moment it is downloaded, we ask you to agree at checkout that supply begins immediately and that you therefore lose that cancellation right once the download starts. Until you download it, you can cancel and get a full refund.
That has nothing to do with faults. If a tune is faulty, not as described, or does not work on the vehicle it was sold for, your rights under the Consumer Rights Act 2015 apply in full: we will repair or replace it, and if that is not possible you are entitled to a refund. Contact us and we will sort it out.
The adapter can be returned unused within 14 days of delivery for a full refund under the Consumer Contracts Regulations 2013. Faulty hardware is covered separately by your statutory rights.
Availability and changes
We aim to keep the service running, but we cannot promise it is always available. Flashing needs our servers, and maintenance happens. We will give notice of planned downtime where we reasonably can.
We may change or withdraw features, and we may change these terms — to reflect a change in the law, a new feature, or how the service actually works. We will publish the new version here and change the date at the top, and where a change materially affects you we will tell you before it takes effect. If you do not accept a change, you can close your account; tunes already flashed to your car stay on it.
Suspension and termination
You can close your account at any time from Settings in the app. We may suspend or close your account if you breach these terms, if we are required to by law, or if we reasonably believe the account is being used to harm someone. Where we can, we will warn you first and give you a chance to put it right.
Closing your account does not remove a tune already written to your ECU, and does not entitle you to a refund of licences already supplied. Flash back to stock first if that is what you want.
Our liability to you
Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, for breach of the terms implied by the Consumer Rights Act 2015, or for anything else that cannot lawfully be limited.
Subject to that, we are not liable for loss or damage caused by: a write you interrupted or a battery you did not charge; a fault that already existed in your vehicle; use of the vehicle outside the law or beyond its mechanical limits; modifications made by anyone other than us; or your failure to declare a modification to your insurer.
We are liable for loss you suffer that is a foreseeable result of us breaking these terms or failing to use reasonable care and skill. We are not liable for loss that was not foreseeable, nor — where you use the service for business purposes — for loss of profit, revenue, contracts, goodwill or business opportunity.
Except for the liabilities in the first paragraph of this section, our total liability arising out of or in connection with these terms is limited to the amount you paid us in the 12 months before the claim arose.
Events outside our control
We are not responsible for delays or failures caused by events outside our reasonable control, including network and hosting outages, supplier failure, industrial action, and government restrictions. If such an event happens we will tell you and do what we reasonably can to limit the effect. If it lasts more than 30 days either of us can end the agreement, and we will refund anything you paid for something you have not received.
General
- We may transfer our rights and obligations to another organisation, and will tell you if we do. You may only transfer yours with our written agreement.
- If a court finds part of these terms unlawful, the rest continues to apply.
- If we delay enforcing a term, that is not a waiver of it.
- These terms, together with our privacy policy, are the whole agreement between us about the service.
- Nobody other than you and us has any right to enforce these terms.
Complaints, law and disputes
Email info@mobileflashsolutions.com first, because most things are quicker to fix that way. We aim to acknowledge a complaint within two working days and resolve it within 14.
These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction. If you live in Scotland or Northern Ireland you can also bring proceedings in your local courts.
