Warranty & Claim Submission

How our warranty works, what it covers, and how to submit a claim.

Coverage at a glance

All products carry a 6-month warranty from the date of delivery, unless a longer period is stated on the product page.

Cover applies to defects in materials and workmanship under normal operating conditions. Most claims are resolved without returning the part.

1. What the Warranty Covers

Covered
  • Defects in materials or workmanship
  • Units that fail to function on arrival
  • Premature failure under normal operating conditions
  • Incorrect item supplied against your order
Not covered
  • Normal wear and consumable deterioration
  • Improper or incorrect installation
  • Unauthorized disassembly, repair or modification
  • Contaminated fuel, oil or coolant
  • Incorrect voltage, poor earthing or wiring faults elsewhere on the machine
  • Damage caused by another failed component
  • Configuration errors from an incorrect ESN or VIN supplied by you

Tampering voids cover. Any disassembly, opening of sealed housings, removal of serial labels or attempted repair by a third party will void the warranty on that unit.

2. How to Submit a Claim

1
Stop using the part
If you suspect a fault, stop using the component. Continuing to run a faulty part can cause secondary damage that is not covered.
2
Gather your evidence
Collect the information listed in section 3 below. Claims submitted with complete information are usually assessed the same day; incomplete claims require a second round of correspondence and take longer.
3
Submit the claim
Use the form at the bottom of this page, or email help@liuchuangparts.com with your order number in the subject line. For urgent downtime, message us on WhatsApp.
4
Technical assessment
Our technicians review your photographs, fault codes and diagnostic data. Many faults can be identified remotely, and a large share of claims are resolved at this stage without returning anything.
5
Return only if requested
Do not ship anything back before we ask you to. Where bench evaluation is required, we will confirm the return address and the shipping arrangement in writing first. Items returned without authorization may be refused or returned to sender.
6
Resolution
Where a claim is approved we will repair, replace or refund at our option. Replacements are dispatched by express courier.

3. What to Include

Send all of the following in your first message. This is the single biggest factor in how quickly your claim is settled.

Order number
Shown in your order confirmation email and in your account
Part number
As printed on the unit, plus a clear photo of the label
Machine details
Make, model, engine model and ESN or VIN
Installation date
And approximate operating hours since fitting
Fault description
What the machine does, when the fault appears, and whether it is intermittent or constant
Fault codes
Active and logged codes read with a diagnostic tool, if available
Photographs
The unit as installed, the part label, any visible damage, and the connector or wiring interface
Video (helpful)
A short clip showing the fault occurring often settles a claim in one round

4. Timeline

24 hrs
First response to your claim, Monday to Saturday
1–3 days
Technical assessment once complete information is received
3–5 days
Bench evaluation after a returned unit arrives, where return is required

5. Specific Product Notes

ECM / ECU controllers

Modules are configured to the ESN or VIN you supply at the time of ordering. A unit that does not communicate because an incorrect ESN or VIN was supplied is not a warranty fault, and the unit cannot be returned for change of mind. If a module is defective on arrival, we will replace or refund it in full. Please include a scan-tool screenshot showing the communication attempt with your claim.

Fuel injectors and injection pumps

Service life depends heavily on fuel quality, filtration condition and installation practice. Claims on fuel system components should include your fuel filter change record and, where available, a fuel sample analysis. Damage caused by contaminated or water-affected fuel is not covered.

Wiring harnesses

Please include photographs of both connector ends and of the routing as installed. Damage from chafing against unprotected edges, heat exposure from incorrect routing, or rodent activity is not covered.

6. What the Warranty Does Not Include

Unless required by law, warranty cover does not extend to:

  • Labour to install, remove, inspect or diagnose a part
  • Machine downtime, lost production or lost revenue
  • Rental or replacement machine costs
  • Towing, recovery or transport of the machine
  • Secondary damage to the machine or to other components

Maximum liability. Where liability is established, our total liability shall not exceed the purchase price paid for the specific item giving rise to the claim, to the fullest extent permitted by the laws of your jurisdiction.
