Terms & conditions

Last updated: 28 August 2026

1. Who we are

The online store at www.dieselsolution.eu ("the store") is operated by Mako Travel EOOD, trading as Diesel Solution, company registration number 204709410, VAT number BG204709410, registered at Mladost 1, Block 75, Entrance 4, Floor 8, Sofia, Bulgaria, with its workshop and correspondence address at 66A Okolovrastna St, 1532 Kazichene, Sofia, Bulgaria ("we", "us"). Contact: office.dieselsolution@gmail.com, +359 895 343 537 (Bulgaria) or +49 176 25096104 (other EU countries), Monday to Friday 09:00–17:00 EET.

2. What these terms cover

These terms apply to every order placed through the store and to repair and remanufacturing services ordered through it. By placing an order you accept these terms. Where you are a consumer, nothing in these terms limits the rights you have under the applicable consumer-protection law; where those rights and these terms differ, your statutory rights prevail.

3. Products and conditions

We sell diesel and petrol injectors, fuel pumps and related components in the conditions shown on each product page: new, reconditioned (exchange), manufacturer-remanufactured (exchange), or repair service for your own unit. Product data, part numbers and vehicle compatibility are provided with care from manufacturer and catalogue data, but the compatibility of a part with a specific vehicle depends on the vehicle's exact specification. You are responsible for verifying the part number against your vehicle or asking us before ordering.

4. Ordering and the contract

Your order is an offer to buy. We confirm receipt by email; the contract is formed when we accept the order by dispatching the goods or by confirming the service. We may decline an order, for example where a part is unavailable, mispriced, or where compatibility cannot be confirmed; any payment already made is refunded in full. Some conditions are priced on request: for those you receive a quote by email and no contract exists until you accept it.

5. Prices and payment

Prices are shown in euro and include VAT. Delivery within Bulgaria is free; for other EU countries one flat courier rate per order is shown at checkout before you pay. We accept bank transfer, debit and credit card and online payment through the checkout, cash on delivery within Bulgaria only, and payment by invoice for approved business customers. Orders are dispatched once payment, including any deposit, has been received, except for cash-on-delivery orders.

6. Exchange units and the core deposit

Reconditioned and remanufactured parts are supplied on an exchange basis: they are sold against the return of your old unit ("the core"). You may hand the core to the courier on delivery, or pay a refundable deposit of €50 per injector and €150 per fuel pump, added automatically in the cart.

  • Return the core within 30 calendar days of receiving your order, in the packaging the remanufactured part arrived in. Return transport is paid by you.
  • We inspect each core on receipt. Cores are accepted when they are complete and undamaged: no mechanical damage, not dismantled, no damage to the body from improper use, connector, magnet unit and nozzle present, no heavy corrosion, and a legible part number. The current criteria with photographs are published on the How it works and Returns & warranty pages.
  • Accepted cores: the deposit is refunded in full within 3–5 business days after inspection, by the payment method of the original order.
  • Cores that do not meet the criteria, or that arrive after 30 days, are not eligible for a deposit refund and remain with us for environmentally sound disposal.

7. Repair service for your own unit

We accept removed injectors and pumps only; we do not carry out vehicle diagnostics or removal. After diagnosis you receive a report and a repair offer; work starts only when you accept the offer. Units that cannot be economically repaired are returned or, at your request, disposed of. Transport to and from our workshop is at your cost unless agreed otherwise.

8. Delivery

We dispatch from Sofia, Bulgaria within 24–48 hours on business days after payment is confirmed for in-stock items — by Econt within Bulgaria and by tracked courier (for example FedEx) to other EU countries. Delivery times after dispatch depend on the destination. Risk passes to you on delivery. If a parcel arrives damaged or is lost, contact us immediately: we open a claim with the courier and aim to resolve it within 5 business days, failing which we send a replacement.

9. Right of withdrawal (consumers)

If you are a consumer in the European Union, you may withdraw from a distance purchase within 14 days of receiving the goods without giving a reason, by telling us clearly (email is enough; a model withdrawal form is available on request). Return the goods within 14 days of your notice, unused, undamaged and in their original packaging; you bear the direct cost of returning them. We refund the price paid, including standard outbound delivery, within 14 days of receiving the goods back or proof of their return. The right of withdrawal does not apply to services fully performed with your consent (a completed repair) or to parts that have been installed, coded to a vehicle or otherwise used. Business customers have no right of withdrawal; wrongly ordered parts are not taken back.

10. Warranty

All parts carry a one-year commercial warranty from the delivery date against defects in materials and workmanship under normal, intended use, in addition to any statutory guarantee of conformity that applies to consumers. The warranty does not cover damage from improper use, incorrect installation, a contaminated or poorly maintained fuel system, a defective fuel pump, ECU software changes (tuning, DPF/EGR removal), non-original fuel filters, a faulty turbocharger, normal wear, unauthorised modification or opening, or external events. To claim, contact us with proof of purchase, the bench-test protocol supplied with the part and a description of the fault; we may ask you to return the part for inspection. Claims are reviewed within up to 30 working days. Where a defect is confirmed we repair or replace the part free of charge; a repair or replacement does not extend the original warranty period. Warranty decisions are based on bench-test protocols, which are attached to the final report.

11. Liability

We are liable without limitation for death, personal injury, fraud and for any liability that cannot be limited by law. Otherwise our liability for any order is limited to the price paid for it, and we are not liable for indirect losses such as vehicle downtime or loss of business. Nothing in this clause limits your statutory rights as a consumer.

12. Personal data

We process personal data as described in our Privacy policy. The store uses cookies as described in our Cookie policy; you can manage your choices on the Privacy & data page.

13. Law and disputes

These terms are governed by Bulgarian law. Consumers also enjoy the protection of the mandatory provisions of the law of their country of residence. Disputes that cannot be settled amicably are heard by the competent courts in Sofia, Bulgaria, without prejudice to a consumer's right to sue in their home courts. The European Commission's online dispute resolution platform is available at https://ec.europa.eu/consumers/odr. We are not obliged and not willing to take part in dispute resolution proceedings before a consumer arbitration board.

14. Changes

We may update these terms; the version in force when you place an order applies to that order.
