For peace of mind, all Diesel Power® and MultiMotion® products are backed by a 3-year warranty, from the original date of purchase.

It's important to note, that the legally regulated liability, for material defects (warranty), cannot be excluded by the vehicle manufacturer, even with tuning measures, as long as the installed component, has the necessary approvals, such as E1 certification and TÜV parts certificate.

This means, that the vehicle manufacturer must honor warranty claims, even if non-factory-approved accessories have been installed, unless it can be proven, that the damage was caused by a non-factory component.

Additionally, engine warranties can be arranged through our partner, NSA Insurance. Certified optimization electronics, are designed to safeguard against motor damage, as the safety devices stored in the engine control unit, at the factory are retained.

We advise against relying solely on free, company-internal guarantee insurance, without reinsurance coverage, as benefits may only be provided, if the guarantor has sufficient liquid funds. In most cases, the burden of proof, rests with the customer.

We also offer a 30 day money back guarantee. If you are not satisfied, with the product in any way within 30 days of receipt of the product, please contact the office and lodge your return request. We will issue an RMA number and you can return the goods, at your cost, for a full refund of the original order value.
