The Buyer sends the original, read computer files to Dieselfiles via the website of Dieselfiles.

Dieselfiles then supplies the Files via the file service on the website. Files are delivered approximately between one (1) hour and two (2) working days. If the Buyer wants the files to be delivered faster, Dieselfiles recommends contacting them by e-mail in advance. When using the file service, the Buyer receives an e-mail for every modification that is ready.

3. The Buyer will promptly provide Dieselfiles with any useful and necessary data or information and fully cooperate in order to properly perform the agreement, at all times.

In principle, credits are valid indefinitely. However, if the Buyer has not use his account, credits will expire after one year, in accordance with the appropriate statutory limitation periods. Any refunds will also be settled with the Buyer by means of credits to the Buyers account.

1. All intellectual property rights, including the rights on the software, the Files and Products delivered by Dieselfiles, including preparatory material and related materials, in the broadest sense of the word, rest with Dieselfiles. For the use of the Files in the vehicle in question, Dieselfiles grants the Buyer a limited, non-exclusive licence to use the Files in a single vehicle. These terms and conditions and/or agreement do not constitute a transfer of intellectual property rights to the Buyer in any way.

2. Without the explicit written consent of Dieselfiles, the Buyer is not permitted to change, edit, publish or multiply the aforementioned works of Dieselfiles, to prepare them for consultation or multiplication via the Internet, or to copy them for use other than exclusively for the Buyer’s own use. Buyers who purchase Files for one of their customers are entitled to use the Files for that customer or that vehicle once.

3. If the Buyer infringes the intellectual property right of Dieselfiles, it will be regarded as non-fulfilment of the agreement, which gives Dieselfiles the right to dissolve or suspend the agreement, and to demand compensation for any damage from the Buyer.

4. In the event of a violation or infringement of the intellectual property rights of Dieselfiles, the Buyer also owes Dieselfiles a penalty of €2,500 per event and €500 for each day (or part thereof) that the violation continues, without prejudice to Dieselfiles’ right to claim full compensation from the Buyer on top of that.


1. Claims and/or complaints in relation to the work carried out, must be announced to Dieselfiles in writing within five (5) working days of delivery and/or availability thereof. If the event that the fault could not reasonably have been discovered within this term, the Buyer has to report this to Dieselfiles in writing within a reasonable period, yet within at least one (1) month. In the latter case, the Buyer has to prove that the subject of his complaint could not have reasonably been discovered sooner.

2. Complaints about Files must be submitted to Dieselfiles within the term referred to in paragraph 1, as detailed as possible, along with a correct (technical) report, logfile or generated error code, from which it is clearly apparent that the complaint and substantiation ensue.

3. Claims do not suspend the Buyers obligation to pay. The Buyer is never entitled to postpone or refuse payment on the basis of a claim or to suspend or refuse payment of other services of Dieselfiles.

4. When a claim is justified with regard to a delivered File, the Buyer can choose to have the File rejected by him repaired, to have the calculated invoice amount proportionally adjusted or to have the agreement not (or no longer) performed in full or in part, provided this is in proportion to the complaint. Refunds are always made in credits.

5. If the Buyer has not submitted a complaint or has not fulfilled the obligation (or burden of proof) referred to in paragraph 2 within the term referred to in paragraph 1, all his rights of whatever nature in relation to his complaint or which he could have complained about within that term and would have had to demonstrate, will lapse.

6. The Buyer has to prove that the complaint is not the result of the use of poorer quality third-party equipment.


1. Dieselfiles warrants the proper performance of the delivered Files in itself (without having been installed) for a twelve month period counting from the delivery date, provided the Buyer pays the invoice in time. If during this period the Files performance shows imperfections, Dieselfiles will remedy this free of charge, subject to the provisions in the previous article. However, the Buyer is personally responsible for properly installing the Files in the vehicle and the requested modification. Dieselfiles advises the Buyer, also dealer, to limit any warranty furnished to its customer by means of the text below, which conditions also apply to any installations of Files by Dieselfiles at Buyers.

2. In addition to these terms and conditions, Dieselfiles applies further provisions when it installs the Files itself, to which situation these terms and conditions are in principle not applicable. If the Buyer asks Dieselfiles to also install the Files in the vehicle, the parties hereby agree that the additional terms and conditions for the installation of Files as seen on the website of Dieselfiles also apply. If a Buyer, who takes care of the installation for his customer, wishes to apply similar warranty provisions, Dieselfiles can make a copy of the provisions in question available to the Buyer for the latter’s own use.


1. The Buyer is aware of the fact that the use or deployment of the Files may violate (local) legislation, is banned or that it may violate the (warranty) rights of third parties such as the manufacturers of vehicles. The Buyer declares that he will use the Files and/or the vehicle in which they are installed at his own risk and that he is individually responsible to investigate or ask if the use or application of the Files is permitted. For that reason, Dieselfiles hereby urgently advises the Buyer to use the Files only on private land and/or on a test or racing track, in accordance with the above.

2. The Buyer realises that the use of the Files may pose a (greater) burden on the vehicle, the potential consequences of which are at the expense and risk of the Buyer.

3. Dieselfiles is only liable for damage suffered by the Buyer that is the direct result of an attributable shortcoming of Dieselfiles to fulfil its best efforts obligations.

4. Dieselfiles is never liable for indirect damage, including consequential damage, lost profits, the (temporary) inability to use a vehicle, fines, lost savings and/or damage due to business interruptions or the expiry of manufacturers warranties.

5. Dieselfiles is not liable for damage that is the result of the Buyer failing to fulfil his duty of disclosure, his obligation to investigate and instructions ensuing from these terms and conditions or the result of the Buyer providing incorrect, incomplete or unreliable information, or the result of incorrect or unlawful use of the Files.

6. Dieselfiles is at all times entitled to limit damage suffered by the Buyer to the greatest possible extent or to undo it, in which the Buyer is obliged to cooperate. The Buyer himself is also obliged to reduce damage to a minimum.

7. The Buyer indemnifies Dieselfiles against any third-party claims with regard to damage in connection with or ensuing from the work carried out or Files delivered by Dieselfiles, if and insofar as Dieselfiles is not liable for that towards the Buyer pursuant to the provisions in this article.

8. If the Buyer has insured any risks in connection with this agreement or if he can invoke any other (warranty) right, the Buyer hereby indemnifies Dieselfiles against such risks.

9. Dieselfiles will exclude liability in at least the following situations (this list is not exhaustive):

• Damage to the hardware or the vehicle as a result of the Files delivered by Dieselfiles;

• Damage in connection with defects and/or parts of objects or (software) files provided by the Buyer;

• Damage to the vehicle itself and/or objects in the vehicle (cargo) when installing the Files;

• Damage as a result of incomplete and/or incorrect information provided by the Buyer;

• Damage as a result of an incorrect quote or budget on the part of Dieselfiles;

• Damage as a result of advice given, products or services provided by third parties for the Buyer;

• Damage as a result of transport, temporary storage or the objects being given by the Buyer for processing;

• Damage as a result of modifications, overwriting, or de-installation of the Files delivered;

• If the vehicle, Files have been presented for recovery or repairs to another party without the explicit written consent of Dieselfiles;

• If the defect can be fully or partially blamed on incorrect use, incorrect actions by the Buyer, manipulation of the Files and/or the engine management system after delivery by Dieselfiles, or if it can otherwise be attributed to the Buyer;

• Personal injury directly or indirectly related to Files delivered by Dieselfiles. Before the Buyer invokes the liability regime in this article, Dieselfiles must comply with the conditions in article 8 in connection with the prompt and correct submission of a complaint and give Dieselfiles the opportunity to take (corrective) measures. If Dieselfiles is not given the opportunity (to correct matters), the Buyer is in principle not entitled to compensation.

10. In the event that Dieselfiles does appear to be liable in connection with the work carried out and/or Files, its liability, following on from the provisions above, is regulated as follows and limited to (in separate and descending order):

• The amount that can be recovered from third parties and/or auxiliary persons that were engaged;

• The amount that the insurer of Dieselfiles may pay out;

11. If the liability of Dieselfiles does not fall under the aforementioned exclusions and Dieselfiles still appears to be liable at law, its contractual and/or statutory liability is limited to either free recovery or redelivery of defective Files, or to compensation to the amount of the invoice amount for the Files, but at all times subject to a maximum of €1,000 (in words: one thousand Euros). The only exception to the aforementioned list is when the damage is caused by intent or gross negligence on the part of Dieselfiles.

12. The limitations of liability set out in this article’s provisions above are also stipulated for the third parties engaged by Dieselfiles for the performance of the agreement, which means they can invoke those limitations of liability directly.


1. Defects and attributable shortcomings on the part of Dieselfiles must be reported to Dieselfiles in writing within a reasonable period after having been discovered, but at least within one (1) month of delivery of the Files, or execution of the work, failing which the right to compensation lapses.


1. The Buyer indemnifies Dieselfiles against all third-party claims in connection with services, objects and/or products delivered to the Buyer by Dieselfiles, as a result of which those third parties may have or may still incur damage, regardless of the cause or time at which the damage has arisen.


1. If any of the provisions in these terms and conditions appear to be fully or partially null, nullified or otherwise invalid, it will not affect the validity of the other provisions in these terms and conditions. The provisions that are legally invalid or that cannot be legally applied will be replaced by provisions that coincide with the purport of the provisions to be replaced to the greatest possible extent, which the parties will consult each other about.

2. In the event of uncertainties regarding the interpretation of one or more provisions of these terms and conditions, the interpretation must be ‘in the spirit’ of these provisions in these terms and conditions.


1. All agreements concluded under these terms and conditions are governed exclusively by Lithuanian law, while international treaties such as the Vienna Sales Convention are hereby explicitly excluded if and to the extent possible.

2. Disputes will be submitted to the competent court of the Lithuania.
