7. PERFORMANCE OF SERVICES & STRUCTURAL INTEGRITY RISKS
7.1. Service Standard: The Company tests serviced units against OEM baseline specifications parameters (measured in kPa and mbar flow), providing a Performance Report upon completion.
7.2. Pre-Existing Thermal / Mechanical Fatigue: The Customer acknowledges that DPF, CAT, and DOC units operate under extreme thermal and pressure stresses. The restoration process (incorporating pneumatic, thermal, and hydraulic cycles) may reveal or exacerbate pre-existing latent structural faults, including substrate cracking, melting, core erosion, or substrate shifting (e.g., DOC shifting into the temperature sensor port).
7.3. Liability Exclusions for Pre-Existing Damage: The Company accepts no liability for structural collapse or substrate breakdown caused by pre-existing vehicle faults or latent heat damage. The Customer remains liable for the diagnostic/service fee incurred in processing the unit in good faith.
7.4. Prior DIY Chemical Treatment: The Customer must disclose if “on-car” cleaning foams, solvent additives, or home remedies were applied prior to submission. Undisclosed chemical saturation can cause catastrophic thermal shock during professional cleaning, voiding all Company liability and warranties.
8. LIMITATION OF LIABILITY & CONSUMER LAW
8.1. To the maximum extent permitted by law (including the Competition and Consumer Act 2010 (Cth) and Australian Consumer Law), the Company’s liability for any breach of statutory guarantee or contractual duty is limited, at the Company’s sole discretion, to:
- In the case of Goods: replacement of the Goods, supply of equivalent Goods, or payment of the cost of replacing the Goods.
- In the case of Services: re-performing the restoration service or refunding the original service fee paid.
8.2. Exclusion of Consequential Loss: Under no circumstances shall the Company be liable for indirect, incidental, special, or consequential loss or damage, including but not limited to loss of profit, workshop labor for removal and re-installation (R&R), vehicle rental/demurrage fees, towing costs, or loss of commercial revenue.
9. GOVERNING LAW AND JURISDICTION
These Terms are governed by and construed in accordance with the laws of the State of New South Wales, Australia. The parties submit to the exclusive jurisdiction of the courts of New South Wales.
SCHEDULE 1: SERVICE WARRANTY & MANDATORY TECHNICAL CHECKLIST
SERVICE WARRANTY COVERAGE: 12 MONTHS / 40,000 KM (WHICHEVER OCCURS FIRST)
This Warranty applies to new replacement units supplied by DPF HQ and serviced/restored units that have passed post-cleaning flow mbar and backpressure (kPa) certification.
The Company warrants that serviced units leave the workshop in a fully functional state tested against OEM guidelines. Because DPF blockages are almost exclusively a symptom of upstream engine, fuel, or sensor malfunctions rather than a primary filter failure, strict compliance with the installation checklist below is mandatory.
1. Mandatory Pre-Installation Diagnostic Requirements
Prior to prolonged test running, the fitting technician/workshop MUST inspect, verify, and resolve all upstream engine systems:
| Engine System | Mandatory Inspection & Verification Protocol |
|---|---|
| Diagnostic Codes | Perform full diagnostic scan; ensure no residual fault codes are stored in the ECU. |
| Induction & EGR | Verify EGR valve and air intake system operation. Check for boost leaks, carbon blockages, and hose delamination. |
| Fuel System | Check injectors, fuel dosing pump, flow control valves, glow plugs, and verify no over-fueling (white smoke). |
| Sensors & Wiring | Test delta pressure sensors, pressure pipes/lines, O2 sensors, and exhaust temperature sensors for correct values. |
| Lubrication | Must execute a fresh engine oil and filter change using NEW Low-SAPS (Low Ash) engine oil. Inspect turbo blades and seals for oil leaks. |
| Exhaust Integrity | Check for upstream exhaust leaks, correct exhaust brake operation, and verify timing belt condition. |
2. Mandatory ECU Reset and Forced Regeneration Protocol
CRITICAL REQUIREMENT: Upon refitting the new or serviced unit, the technician MUST instigate an in-car ECU reset / adaptation procedure and forced regeneration burn prior to road testing. This allows the Engine Control Unit (ECU) to reset soot/ash values and learn the new baseline backpressure levels. Failure to perform this step will result in rapid re-clogging and VOIDS WARRANTY.
3. Installation Consumable Guidelines
- Gaskets & Hardware: Always install NEW OEM-quality gaskets, nuts, and bolts. Ensure all threaded fittings receive high-temperature anti-seize lubricant to prevent cold welding.
- NO SEALANTS: DO NOT apply silicone sealant, exhaust paste, or liquid gasket compounds upstream of the DPF, DOC, or CAT. Exhaust paste breaks down under heat and permanently damages the microscopic wall-flow ceramic substrate.
- Torque Specs: It is the fitting technician’s responsibility to verify all nuts, studs, and sensor ports are correctly torqued prior to operation.
4. Warranty Exclusions and Voiding Conditions
Warranty coverage will be strictly VOIDED under any of the following circumstances:
- Undiagnosed Upstream Faults: Failure to identify and correct upstream issues (e.g., leaking injectors, failed turbo, faulty EGR, broken glow plugs) prior to vehicle operation.
- Oil / Fuel Contamination: Thermal substrate damage caused by raw fuel or oil saturation (e.g., turbocharger seal failure). Servicing oil-saturated units carries a limited structural warranty only, as chemical catalyst poisoning cannot be reversed.
- Unapproved Additives: The use of bio-fuel blends, foreign fuel additives, or aftermarket “on-car” foam spray cleaning chemicals.
- ECU Reset Omission: Failure to carry out mandatory ECU soot data reset and forced regeneration upon installation.
- Physical Overheating: Casing discoloration (turning blue/purple) indicating extreme external heat caused by unburnt fuel igniting within the filter housing.
- Exhaust Paste Usage: Presence of exhaust paste or silicone sealant residue within the filter substrate or sensor ports.
- Separation of Catalysts: Failure to service the DOC or CAT upstream along with the DPF (unserviced upstream catalysts cause rapid DPF soot accumulation).
