Terms and conditions

Read these terms before making an appointment or placing an order. Consumers always retain the rights that cannot legally be excluded.

1. Identity, definitions and applicability

These terms apply to every offer and agreement of Van Toor Solutions, trading as ChiptuningDelfzijl, hereinafter “CTD”. Current contact, Chamber of Commerce and VAT details are stated on the website and in the job or order confirmation.

“Customer” means any natural person or legal entity dealing with CTD. “Consumer” means a customer not acting for professional or business purposes. “Vehicle” also includes its ECU, TCU, software, drivetrain and other systems. “Work” includes diagnostics, fault investigation, chip tuning, data logging, software programming and related technical actions.

Deviations apply only when agreed in writing. If any provision is invalid, the remaining provisions remain effective and the invalid provision is replaced by a valid provision that reflects its purpose as closely as possible.

2. Offers and formation of the agreement

Quotes and price indications are non-binding unless a validity period or binding nature is expressly stated. An agreement is formed upon written or electronic acceptance, a confirmed appointment, payment, or when CTD starts the work with the customer’s permission. Obvious clerical, calculation or input errors do not bind CTD.

The job includes only what is described in the confirmation. Additional work will be discussed in advance where possible. If immediate action is required during the work to prevent further damage or an unsafe situation, CTD may take reasonable emergency measures and will contact the customer as soon as possible.

3. Prices and payment

Consumer prices include VAT unless clearly stated otherwise. Business prices may be shown excluding VAT. Payment is due at the agreed time and no later than collection of the vehicle or before dispatch of a product. CTD may require a deposit and suspend performance or delivery while due amounts remain unpaid.

If payment is late, a consumer first receives the legally required free reminder and payment period. Statutory interest and legally permitted collection costs may then be charged. Business customers owe statutory commercial interest and reasonable extrajudicial costs from the due date.

4. Appointments, cancellation and no-shows

An appointment may be moved or cancelled free of charge up to 24 hours before the agreed start, unless custom software or other non-reusable performance has already been purchased with express permission for the job. For cancellation within 24 hours, late arrival or a no-show, CTD may charge its reasonable and demonstrable loss, including reserved time and external costs already incurred, up to the agreed price. The customer may demonstrate that the actual loss is lower. Statutory withdrawal rights remain unaffected.

CTD may reschedule an appointment in the event of illness, technical failure, unsafe conditions, force majeure or where essential information or access to the vehicle is missing. CTD will then arrange a reasonable new date at no extra cost.

5. Customer’s duty to provide information

Before work starts, the customer provides correct and complete information about registration, VIN, engine and transmission type, mileage, maintenance, warning messages, damage, previous tuning, dealer updates, engine or transmission swaps, aftermarket parts and other relevant changes. The customer confirms authority to commission work on the vehicle.

Consequences of incorrect, incomplete or withheld information are for the customer’s account insofar as they cannot be attributed to CTD. If CTD discovers relevant unknown circumstances, it may pause, adjust or refuse the work.

6. Technical assessment and refusal

Before or during the work, CTD may read fault codes, verify vehicle data, perform a visual inspection and, where necessary, carry out a test drive or data log with permission. This assessment is a snapshot and is not a full pre-purchase inspection, safety inspection or guarantee that all hidden defects have been found.

CTD may refuse or stop work if the technical condition, fault codes, software integrity, parts used, requested calibration, law or safety gives reason to do so. Correctly completed diagnostic work and demonstrable external costs already incurred remain payable.

7. Performance, test drives and data logging

CTD performs the job with reasonable professional care and may engage specialist third parties or software suppliers for parts of the work. The customer permits technically necessary test drives, idling, load building and data logging. CTD limits these actions to what is reasonably necessary and complies with traffic rules.

The customer provides sufficient correct fuel, a roadworthy vehicle, valid documents and, where required, insurance and permission for the test drive. Traffic fines demonstrably caused by CTD during a test drive are borne by CTD.

8. Existing defects, wear and increased load

Chip tuning may increase power, torque, boost pressure and thermal or mechanical load. Existing wear, contamination, inadequate maintenance or weak components may therefore become apparent or fail sooner. This includes the clutch, dual-mass flywheel, transmission, turbo, injectors, fuel system, cooling system, timing components, sensors, catalytic converter, diesel particulate filter and other emissions components.

CTD is not liable for a pre-existing defect, normal expected wear, inadequate maintenance or a failure not caused by a breach by CTD. This article does not exclude liability for demonstrable errors by CTD.

9. ECU/TCU, software and programming risk

Reading, unlocking and writing control units requires stable communication and power. CTD works carefully and, where technically possible, backs up the original software found. A virtual or supplier-obtained original file may be used where a full physical read is not possible.

The customer discloses previous programming, tuning, cloning, immobiliser or repair work. Damage or recovery costs caused by pre-damaged hardware, corrupt or unknown software, undisclosed tuning, incorrect parts, interrupted communication beyond CTD’s control or failure to follow instructions are not borne by CTD unless CTD caused the damage or the law provides otherwise.

10. Power, torque and fuel consumption

Published or discussed power, torque and consumption figures are realistic guidelines and are not guaranteed for every individual vehicle. The result depends on specification, software version, fuel, weather, measurement method, maintenance and technical condition. Only a measurement agreed in writing beforehand and performed under comparable conditions may serve as a binding performance benchmark.

Lower fuel consumption also depends on driving style and use and is not guaranteed. A request for a different or more aggressive calibration after correct delivery is treated as a new job.

11. Stage 2, hardware and third-party parts

For a calibration requiring modified hardware, the customer is responsible for the timely presence and suitability of that hardware unless CTD supplies and installs the parts. CTD may require proof of installation, specifications or additional inspection. Without suitable hardware, CTD may refuse the job or propose a safer calibration.

CTD does not warrant the quality, compatibility or installation of customer-supplied parts or third-party work. If a product supplied by CTD is defective, the customer’s statutory rights remain fully applicable.

12. Law, type approval, insurance and manufacturer warranty

Changes to power, software, emissions or vehicle configuration may affect type approval, registration, roadworthiness testing, manufacturer or dealer warranty, lease terms, insurance and use on public roads. The customer is responsible for having changes assessed, reported and registered where required by law, contract or insurance. On request, CTD provides available information about the modification performed.

CTD may refuse jobs that are unsafe or clearly contrary to mandatory law. A customer request or approval does not make a prohibited modification lawful.

13. Diagnostics and fault investigation

Diagnostics is an obligation of reasonable effort: CTD investigates the complaint carefully but does not guarantee that every fault will be found or resolved within a predetermined number of hours. Reading fault codes is only one part of diagnostics and does not always establish the definitive cause.

The agreed diagnostic fee – including, where applicable, the published rate of €125 – is due for the investigation performed even if no defect is found, repair proves impossible or the customer does not commission follow-up work. Additional investigation or disassembly is discussed in advance, except for necessary emergency measures as referred to in article 2.

14. Delivery, inspection and statutory conformity

The customer inspects the vehicle or product upon delivery as soon as reasonably possible. Visible damage, missing parts or discrepancies should preferably be reported immediately. Failure to report immediately does not affect statutory consumer rights, but the customer must mitigate further damage and allow CTD to investigate the cause.

The service supplied must conform to the agreement and be performed with reasonable care. Products must have the qualities the customer may reasonably expect, taking into account the price, description and clearly stated condition of a new or used product. Statutory warranty is not limited by a commercial warranty period.

15. Complaints, remedy and restoration to original

A complaint must be reported as soon as possible to retour@chiptuningdelfzijl.nl with the order or reference number, registration or VIN, mileage, fault codes, relevant circumstances and a clear description. In a potentially unsafe situation, the customer stops using the vehicle and follows CTD’s reasonable safety instructions.

CTD is first given a reasonable opportunity to inspect the vehicle and remedy a breach attributable to CTD free of charge. Depending on the complaint, CTD may adjust the software or restore the original software as an appropriate remedy. The customer makes the vehicle available within a reasonable period and does not allow a third party to modify the software in the meantime.

If remedy or restoration is impossible, is not completed within a reasonable time or cannot reasonably be required of the customer, statutory rights to a price reduction, termination and any damages apply. An immediate full refund is not due where CTD can still reasonably resolve the complaint free of charge.

Where the tuning was correctly performed and the customer merely changes preference, there is no automatic right to a refund. Restoration to original is then a separate paid job. Mandatory consumer rights and any valid right of withdrawal always remain applicable.

16. Third-party work and software changes

After delivery, dealer updates, manufacturer campaigns, diagnostic equipment, other tuners, replacement or cloning of a control unit and other programming may overwrite or affect CTD software in whole or in part. CTD is not responsible for resulting consequences or recovery costs. Re-supply or adjustment will be quoted in advance.

This article does not deprive the customer of rights where third-party work was necessary because CTD failed to remedy a reported breach within a reasonable time or where prior consultation was not reasonably possible.

17. Liability and mitigation of loss

CTD is liable for direct loss that is the foreseeable and immediate result of an attributable breach by CTD. The customer must take reasonable steps to prevent or mitigate loss and notify CTD as soon as possible. CTD is not liable for indirect or consequential loss, such as lost turnover, lost profit, substitute transport or loss of use, insofar as such limitation is permitted by law.

Where liability insurance provides cover, liability is limited to the amount paid by the insurer plus the applicable excess. If no insurance payment is made, liability is limited – insofar as legally permitted – to the invoice amount for the part of the job to which the loss relates, capped at €2,500. These limitations do not apply in cases of intent or deliberate recklessness by CTD, death or personal injury, product liability where mandatorily regulated, or where a limitation against a consumer is unreasonable or prohibited by law.

18. Vehicle, belongings and storage

The customer removes money and valuable or loose items from the vehicle and reports relevant details about alarm systems, wheel locks, immobilisers or operation. CTD handles the vehicle and keys with care but is not liable for loss of undisclosed or left-behind items unless caused by CTD.

After notification of completion, the customer collects the vehicle within the agreed or a reasonable period. Reasonable storage costs may only be charged after the customer has been warned and given a reasonable collection period.

19. Force majeure

In circumstances beyond CTD’s reasonable control – including power, network or supplier failure, illness, fire, government action or unforeseen unavailability of essential software or parts – obligations are suspended while performance is reasonably impossible. CTD informs the customer as soon as possible. If the situation lasts unreasonably long, either party may terminate the unperformed part; the customer pays only for properly completed performance and specifically authorised costs already incurred.

20. CTD Shop: orders, delivery and risk

A shop order is confirmed after acceptance and, where applicable, payment. Delivery times are estimates unless expressly agreed as strict deadlines. CTD reports delays and offers the consumer the statutory remedies. For a consumer, the risk of loss or damage passes upon receipt by the consumer or a third party designated by the consumer other than the carrier.

Before ordering, check the part number, version and stated compatibility. Compatibility advice from CTD is based on information supplied by the customer. An incorrectly supplied registration, VIN or part number is at the customer’s expense, without prejudice to statutory rights where CTD made the error.

21. Withdrawal period for products

A consumer buying a product at a distance may generally withdraw without reason within 14 days after receipt. The consumer then has a further 14 days to return the product. The consumer bears only the direct return costs where this was clearly communicated before purchase. CTD refunds the amounts legally due within 14 days after notice of withdrawal but may wait until the product is received or the consumer proves dispatch.

The consumer may inspect the product as would be possible in a shop. CTD may deduct a reasonable amount for depreciation caused by more extensive use or installation. The right of withdrawal does not apply to products made to customer specifications or clearly personalised, or to other products excluded by law. A seal or packaging limits the right of withdrawal only where the law permits this for the product concerned.

22. Distance services and immediate performance

For a distance contract for services, a consumer generally has a 14-day withdrawal period from conclusion of the contract. If the consumer wants CTD to begin during that period, CTD will first request an express instruction. If the consumer withdraws after that start, a proportionate amount is due for the part already performed, provided CTD supplied the legally required information and confirmation.

The right of withdrawal expires only after the service has been fully performed and the consumer expressly agreed in advance to immediate full performance and acknowledged that the right of withdrawal would be lost after full performance. Merely accepting these terms is not sufficient; CTD uses a separate confirmation where required.

23. Intellectual property and use of software

Copyright and other intellectual property rights in calibrations, files, methods, reports and documentation developed or used remain with CTD or the relevant rights holder unless otherwise agreed in writing. Payment gives the customer the right to use the supplied software in the agreed vehicle but not to copy, resell, publish, reverse engineer or use files for another vehicle.

Vehicle and measurement data may be processed for performance, quality control, evidence and remedy of the job. Personal data is handled in accordance with CTD’s privacy policy and applicable privacy law.

24. Business customers

Statutory consumer rights and consumer withdrawal periods do not apply to business customers. A business customer indemnifies CTD against third-party claims arising from incorrect information, unauthorised instructions or use of the performance outside the purpose agreed in writing, except to the extent the claim was caused by an attributable error by CTD.

25. Complaints, governing law and disputes

Questions or complaints may be sent to retour@chiptuningdelfzijl.nl. CTD responds within a reasonable time and first seeks a solution together with the customer. Dutch law applies to the agreement. Disputes are submitted to the court having jurisdiction under the law. A consumer retains all mandatory protection and jurisdiction available under applicable national or European law.
