Look beyond paint finish. Structural dimensions, underbody protection, high-voltage isolation, water traces, repair records and calibrated safety systems must agree before a repaired Q05 is priced or shipped.
Reconcile history, documents and physical identity
Request ownership or origin records, insurance or auction disclosures where available, repair invoices, parts invoices and pre-repair photographs. Match every record to the VIN and compare dates with registration, mileage and service history. Search for replaced identity labels, inconsistent fasteners, changed glazing dates and unexplained gaps in use. A clean report is useful but not conclusive where databases have limited coverage. Start with the general used Changan Q05 inspection checklist, then expand the scope whenever panels, airbags, battery protection or water exposure show disturbance.
Keep database limitations visible; “no record found” does not prove no damage.
Measure structure and restraint-system repair
Inspect panel gaps, paint thickness, welds, seam sealer, bolts, lamps, glass, suspension pickup areas, floor, pillars and crumple structures. Use body dimensions or alignment measurements when repair near structural points is suspected. Scan airbag, seat-belt pretensioner and occupant-detection modules and verify warning lamps complete their normal self-test. Replacement covers or cleared codes do not prove restored restraints. Confirm tyre wear, steering-centre position and wheel alignment through a road test. Describe structural repair by location, method and responsible workshop before assessing price and destination eligibility.
Record inspector, equipment and unresolved structural areas.
Inspect battery enclosure and high-voltage safety
View the full underside on a lift. Look for impact marks, deformation, missing shields, non-standard sealant, damaged fasteners, crushed lifting points, coolant traces and repairs near the battery enclosure or orange cables. Add the Q05 battery-health checks, including battery identity, diagnostic state, cell balance where available, isolation or thermal warnings and a controlled charge session. For a PHEV, inspect engine and fuel systems affected by the same event. Do not energise or charge a suspect high-voltage vehicle until a qualified technician determines it is safe.
Photograph the underside by location and retain original files.
Trace flood and moisture evidence
Inspect low points beneath carpets, seat rails, underfloor areas, connectors, fuse boxes, lamps, door cavities and ventilation components. Look for silt, tide lines, corrosion, mineral residue, odour, mould, new carpet over old insulation and multiple unrelated electrical faults. Compare cabin evidence with underbody and document history. Moisture can create delayed connector, sensor and control-module failures after a vehicle appears dry. One normal diagnostic scan cannot rule out prior immersion. Record which interior sections were lifted and which electronic modules were physically inspected.
List every area opened; uninspected cavities remain unknown.
Verify repairs, calibration and commercial impact
Request part numbers for lamps, glazing, bumpers, cameras, radar or ultrasonic sensors affected by repair. Confirm coding and calibration records, then perform function and road tests without treating assistance as autonomous driving. Price cosmetic, structural, restraint, battery, electrical and calibration corrections separately. Check whether the destination restricts repaired, salvage or flood-damaged imports and whether insurers need more evidence. Link the decision to the Q05 ADAS and sensor guide before accepting repaired glass, front-end parts or suspension alignment.
Apply repair cost, eligibility and resale adjustments to the exact candidate.
Record the approval decision
Approve a repaired Q05 only when VIN-linked history and physical evidence agree, structure and restraints meet the defined scope, the battery enclosure and high-voltage system are safe, and moisture checks show no unresolved exposure. Affected sensors require compatible parts, coding and calibration evidence. Destination eligibility, insurance implications and repair cost must be written into the decision. Reject or hold when structural dimensions, restraint status, battery integrity, flood extent or repair identity cannot be established.
Retain the approval with the VIN file and reopen the review whenever the candidate, destination or commercial boundary changes.
Buyer approval checklist
Use these fields as a candidate-specific decision record. Assign each unresolved item before approving payment or shipment.
- VIN-linked damage history
- Structure and restraints
- Battery underside and isolation
- Flood and corrosion evidence
- Sensor calibration records
- Destination repair eligibility

Can a clean history report prove no damage?
No. Combine available records with paint, structure, restraint, underbody, diagnostics and repair documents.
Is a scratched battery shield cosmetic?
Not automatically. Location, deformation, mounts, sealing, isolation and thermal evidence need review.
Why check ADAS after glass or bumper repair?
Cameras and sensors may be shifted or replaced and can require correct coding and calibration.
