Terms of Service

These Terms of Service ("Terms") govern your access to and use of the Professional Diesel Repair website located at professionaldieselrepair.com (the "Site"), including all content, interactive tools, fault code databases, repair guides, blog articles, and related services (collectively, the "Services") provided by Professional Diesel Repair ("we," "us," or "our").

By accessing or using the Site, you agree to be bound by these Terms. If you do not agree to these Terms, you must not access or use the Site. We reserve the right to modify these Terms at any time, and your continued use of the Site following any changes constitutes acceptance of the revised Terms.

Acceptance and Eligibility

You must be at least 16 years of age to use the Site. By using the Site, you represent and warrant that you meet this age requirement and have the legal capacity to enter into these Terms. If you are using the Site on behalf of a business or organization, you represent that you have authority to bind that entity to these Terms.

Description of Services

Professional Diesel Repair provides free access to diesel engine diagnostic information, fault code references, repair cost estimation tools, maintenance planning calculators, and technical educational content. The Services are provided for informational and educational purposes only and are intended to supplement — not replace — OEM service information, certified technician expertise, and applicable safety regulations.

We strive to maintain accurate and current content, but we do not guarantee that all information on the Site is complete, current, or applicable to your specific engine, vehicle, or operating conditions. Diagnostic procedures, part numbers, torque specifications, and cost estimates may vary by model year, engine configuration, geographic region, and shop labor rates.

User Conduct

When using the Site, you agree not to:

• Use the Site for any unlawful purpose or in violation of any applicable local, state, national, or international law.
• Attempt to gain unauthorized access to any portion of the Site, other accounts, computer systems, or networks connected to the Site.
• Use automated systems, including bots, scrapers, or crawlers, to access or extract content from the Site without our prior written consent.
• Reproduce, duplicate, copy, sell, resell, or exploit any portion of the Site or its content for commercial purposes without authorization.
• Submit false, misleading, or malicious information through contact forms or other Site features.
• Interfere with or disrupt the Site's infrastructure, servers, or networks.

Intellectual Property

All content on the Site — including text, graphics, logos, tool interfaces, fault code databases, repair guides, and software — is the property of Professional Diesel Repair or its content licensors and is protected by United States and international copyright, trademark, and other intellectual property laws.

You are granted a limited, non-exclusive, non-transferable license to access and use the Site and its content for personal, non-commercial informational purposes. This license does not include the right to modify, distribute, transmit, display, perform, reproduce, publish, license, create derivative works from, transfer, or sell any Site content without our prior written consent.

OEM part numbers, fault code designations (SPN/FMI), and technical specifications referenced on the Site remain the property of their respective manufacturers. Our use of such references is for identification and educational purposes under fair use principles.

Interactive Tools

Our repair cost estimators, maintenance schedulers, and diagnostic calculators provide estimates based on aggregated market data and published labor time guides. These tools produce approximations only. Actual repair costs depend on shop rates, parts availability, vehicle condition, regional pricing, and technician experience. We make no warranty that tool outputs are accurate for any specific repair situation.

Tool calculations are performed locally in your browser. We do not store your inputs unless you explicitly submit them through a contact form or other data collection feature.

Disclaimer of Warranties

THE SITE AND ALL SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ACCURACY OF INFORMATION.

We do not warrant that the Site will be uninterrupted, error-free, or free of viruses or other harmful components. We do not warrant that diagnostic information, repair procedures, or cost estimates will be accurate, complete, or suitable for your specific application. See our full Disclaimer for additional details.

Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, PROFESSIONAL DIESEL REPAIR AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, AND CONTENT CONTRIBUTORS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, DATA, VEHICLE DOWNTIME, REPAIR COSTS, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE SITE OR SERVICES.

Our total liability to you for any claims arising from your use of the Site shall not exceed the amount you paid to us for access to the Services in the twelve months preceding the claim, or fifty dollars ($50), whichever is greater. Because the Services are provided free of charge, this limitation effectively caps our liability at fifty dollars ($50) for most users.

Indemnification

You agree to indemnify, defend, and hold harmless Professional Diesel Repair and its officers, directors, employees, agents, and content contributors from and against any claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees) arising out of or related to your use of the Site, your violation of these Terms, or your violation of any rights of a third party.

Third-Party Links

The Site may contain links to third-party websites, including OEM manufacturer portals, parts distributors, and technical resources. These links are provided for convenience only. We do not endorse, control, or assume responsibility for the content, privacy policies, or practices of any third-party sites.

Governing Law

These Terms shall be governed by and construed in accordance with the laws of the United States, without regard to conflict of law principles. Any disputes arising under these Terms shall be resolved in the courts of competent jurisdiction, and you consent to the personal jurisdiction of such courts.
