A vehicle that starts once may still have weak reserve capacity, excessive sleep current or a battery-management mismatch that appears during port storage.
Decision boundary
Identify the fitted battery technology, specification, installation date and registration or adaptation requirement for the exact generation. Test state of charge and health with suitable equipment, inspect terminals and grounds, review charging voltage and scan energy-management modules. Verify start-stop only after its operating conditions are understood.
Evidence register
Record the car after normal sleep, after a repeat start and after an agreed standing period. Review recent jump-starts, accessory additions, tracking devices and module faults. Link service planning to maintenance and parts support, and include electrical symptoms in the complete Tiguan inspection.
Where the risk sits
Start-stop may remain unavailable because of temperature, charge, cabin demand or other legitimate conditions; that alone does not prove a fault. Conversely, a recently charged battery can pass a brief demonstration while losing reserve quickly. Incorrect replacement type or unregistered battery work can also affect management behaviour.
Candidate scenario
For a vehicle awaiting sea freight, agree who maintains charge, what devices remain connected and the minimum handover voltage. If repeated discharge cannot be explained, diagnose the draw before loading rather than sending a jump-start problem to the destination.
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 battery identity and age, terminals and grounds, state-of-health test before commercial acceptance. Keep energy-management scan, sleep-current evidence, storage and handover plan 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.
Set rejection rules before the seller discussion
Write which failures in battery identity and age, terminals and grounds, state-of-health test make a Tiguan unsuitable even if the price falls. Separate those from repairable findings and preferences. For every unresolved item, record the maximum acceptable repair, delay or destination consequence. This prevents negotiation from quietly changing the buyer's original standard.
Make the result repeatable
Give a second reviewer the VIN file without the seller's summary. That person should locate the evidence behind energy-management scan, sleep-current evidence, storage and handover plan and explain the pass, hold or reject result. If the answer depends on an undocumented conversation, obtain a dated written statement or leave the field unconfirmed.
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 battery identity and age, terminals and grounds, state-of-health test, energy-management scan, sleep-current evidence, storage and handover plan 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.

Does one successful start prove the battery is healthy?
No. Reserve capacity and repeated standing behaviour also matter.
Does inactive start-stop prove a defect?
No. Many operating conditions can inhibit it.
Should the battery be disconnected for shipping?
Follow carrier, vehicle and safety requirements for the exact shipment.
