1. Diagnostic Nature of Services

Our diagnostic services are intended to identify potential issues with your vehicle's systems. While we use specialized tools and our best efforts to accurately assess your vehicle's condition, diagnostics do not guarantee the identification of all pre-existing or potential problems. Some issues may not be apparent during the diagnostic process and may only become evident under different operating conditions or at a later time.

2. No Guarantee of Repair

This diagnostic report is not a guarantee of a successful repair. The information provided is based on the findings at the time of the inspection. The final cost and timeline for any repairs may vary depending on the actual cause of the problem, the availability of parts, and other factors that may arise during the repair process.

3. Limitation of Liability

To the fullest extent permitted by law, we are not liable for any damages, losses, or expenses, whether direct or indirect, consequential, or incidental, that may arise from the diagnostic services provided. Our liability is limited to the cost of the diagnostic service itself.

4. Authorization to Proceed

Your acceptance of this disclaimer and your authorization to begin diagnostic services grant us permission to operate your vehicle, if necessary, and to connect diagnostic equipment to your vehicle's systems.

5. Customer Responsibility

You are responsible for informing us of any known issues, previous repairs, or modifications to the vehicle that may affect the diagnostic process.

Important Notice

This document serves as a disclaimer regarding the Diesel Particulate Filter (DPF) regeneration process for the vehicle identified below. By proceeding with or authorizing this service, you acknowledge and agree to the terms and conditions outlined in this disclaimer.

Understanding DPF Regeneration

GOV.UK: Modifying your vehicle’s emissions — legal, safety and health implications

The Diesel Particulate Filter (DPF) is a component designed to trap soot and other harmful particles from the exhaust gases. Over time, the DPF can become full, and a process known as "regeneration" is required to burn off the accumulated soot.

Types of Regeneration

Passive Regeneration: Occurs automatically during normal driving conditions, especially at higher speeds and engine temperatures.
Active Regeneration: The vehicle's engine control unit (ECU) initiates this process by injecting a small amount of fuel into the exhaust to raise the temperature and burn off the soot. This may be indicated by a dashboard warning light.
Forced (Manual) Regeneration: A diagnostic tool is used by a technician to manually initiate the regeneration process. This is typically done when passive or active regeneration has failed or when the DPF is significantly blocked.

Risks and Potential Issues

Increased Temperatures: The DPF regeneration process involves extremely high temperatures. There is a risk of heat-related damage to surrounding components, including but not limited to, underbody plastics, wires, and heat shields.
Fire Hazard: Due to the high temperatures, there is a remote risk of fire, especially if the vehicle is parked on or near flammable materials (e.g., dry grass, leaves). The vehicle should always be in a safe, well-ventilated area during the process.
Engine Oil Dilution: In some cases, the regeneration process can lead to diesel fuel entering and diluting the engine oil. This can reduce the lubricating properties of the oil and may require an oil and filter change shortly after the regeneration is completed.
Incomplete Regeneration: The process may not be fully successful, especially if the DPF is severely clogged or if there are underlying engine issues (e.g., faulty sensors, injectors). A failed regeneration may require further diagnostic work or DPF replacement.
Turbocharger Damage: In rare instances, excessive back pressure from a clogged DPF can put a strain on the turbocharger, potentially leading to premature wear or failure.
No Guarantee of Longevity: A successful regeneration does not guarantee the long-term health of the DPF. The filter's lifespan depends on a variety of factors, including driving habits, fuel quality, and proper vehicle maintenance.

Customer Responsibilities

You confirm that you have been informed of the DPF regeneration process and its associated risks. You agree to absolve Marks Mobile Remapping of any liability for damages, injuries, or other issues that may arise as a result of the DPF regeneration. You understand that:
- The vehicle must be in a safe, open area during the procedure.
- You are responsible for any costs associated with additional repairs, part replacements, or an oil change that may be required as a result of a failed or successful regeneration.
- You will be notified if the regeneration process fails and will be presented with options for further diagnosis or repair.

s.76(1) — Fitting parts: offence

If someone fits a vehicle part to a vehicle, or causes/permits it to be fitted, and using that vehicle on a road with that part would either breach the construction & use requirements or create a danger of injury to any person, then that person commits an offence. Legislation.gov.uk

s.76(2) — Defences to (1)

A person is not to be convicted under subsection (1) if they prove either: the vehicle was to be exported from Great Britain; or they had reasonable cause to believe the vehicle would not be used on a GB road, or wouldn’t be used until it had been made compliant with construction & use requirements and safe (no danger of injury). Legislation.gov.uk

s.76(3) — Supplying parts: offence

If a person supplies (or causes/permits the supply of) a vehicle part and has reasonable cause to believe it’s to be fitted to a motor vehicle / a class of vehicle / a particular vehicle, they commit an offence if that part couldn’t be fitted except in circumstances where using the vehicle on a road would either breach construction & use requirements or create a danger of injury.
