A screen icon proves presence, not overseas operation.
Decision boundary
Record infotainment generation, software version, languages, navigation region, phone integration, account status and online-service requirements.
Evidence register
Release previous accounts and demonstrate cameras, sensors and assistance warnings after reboot on the actual vehicle.
Where the risk sits
China-market services may require domestic accounts; unverified coding can affect gateways, keys, security and safety functions.
Candidate scenario
Assign value only to functions demonstrated in the destination account environment.
Version-specific control
Ownership fit begins before shipment. Map the exact hardware to local fuel, fluids, diagnostic equipment, workshop competence, part numbers and software access.
Export and ownership consequence
Give the destination workshop the VIN identity, baseline scan, accepted condition and open maintenance actions. Record who must confirm each open field, what document or test closes it, and when that evidence expires.
Buyer hold points
Mark software version, language, account release before commercial acceptance. Keep phone integration, navigation region, adas operation visible until the responsible reviewer closes them. A changed VIN, beneficiary, delivery point or accepted exception reopens the affected gate.
Arrival handover
Freeze odometer, warnings, keys, accessories, body condition and unresolved actions before loading. Compare arrival condition with the loading file before cleaning or repair, and preserve the record for claims and workshop handover.
Turn uncertainty into a named action
Avoid conclusions such as “looks fine” or “probably standard.” An open question about software version, language, account release should request a precise VIN photograph, legal record, diagnostic result, measurement, road-test observation or destination ruling. Assign an owner and deadline. Do not release payment while missing evidence can change safety, legality or a high-cost repair.
Prepare the receiving workshop
The destination handover should identify the generation, legal model, powertrain, keys, service evidence, diagnostic baseline and accepted condition. Include decisions about phone integration, navigation region, adas operation. This reduces wrong-part orders and helps distinguish shipping damage from a pre-existing issue.
Audit the file before approval
Translate technical findings into a destination ownership plan. Identify the exact service fluids, diagnostic capability, software region, consumables and version-specific parts before assigning value to equipment. Ask a local workshop what it can actually support, especially for DSG, 4MOTION, PHEV, cameras and driver-assistance calibration. A feature that cannot be maintained, activated or repaired in the destination should not be priced as if full support were guaranteed.
Read the record as if the original salesperson were unavailable. The conclusion about software version, language, account release, phone integration, navigation region, adas operation should remain traceable to dated evidence. Resolve contradictions rather than selecting the most convenient source, and preserve every market, year, test-condition or quotation-period limit beside the claim. Record the reviewer, review date, unresolved questions and next expiry point so another person knows what must be refreshed before approval.
Record the decision, not just the data
Finish with pass, hold or reject. A hold names the missing evidence, owner and deadline. Approval means the remaining limits are understood; it does not turn an unknown into a confirmed feature.
Keep a dated source beside every material conclusion. If the seller changes the vehicle, repeat the affected checks instead of carrying approval to another VIN or model year.
