Assistance equipment varies by generation, market and trim; a feature list from another Tiguan cannot establish this VIN.
Decision boundary
Inventory cameras, radar, parking sensors, windscreen hardware and controls. Volkswagen lists Front Assist, Lane Assist, Side Assist and other systems on current Tiguan configurations, but optional content varies. Contract only functions proven on the candidate.
Evidence register
Inspect glass and camera brackets, bumpers, grille, radar mounts, suspension repairs, wheel geometry and tyres. Scan relevant modules. After windscreen, body or suspension work, request the applicable calibration procedure and report, then perform safe functional checks. Confirm installed functions through the software and ADAS evidence file and connect any repaired sensor area to the structural-repair assessment.
Where the risk sits
A sensor may be present without a warning yet still be misaligned. Replacement glass, non-standard parts, wheel changes and poor alignment can affect operation. ADAS remains driver assistance, not autonomous driving.
Candidate scenario
A candidate with a replacement windscreen and no calibration record remains on hold even if lane graphics appear. Confirm hardware, scan status and calibration. Do not mark a lower trim defective merely because it lacks an optional function.
Version-specific control
Condition must be observed on one vehicle. Preserve cold and hot results, module scans, dated media and service evidence. Classify each finding by consequence and evidence rather than by cosmetic impression.
Export and ownership consequence
A discount can compensate for an understood repair; it cannot prove legal identity, structural safety or destination eligibility. Record who must confirm each open field, what document or test closes it, and when that evidence expires.
Buyer hold points
Mark exact system inventory, sensor and bracket condition, glass and repair history before commercial acceptance. Keep tyres and alignment, diagnostic scan, calibration record 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 exact system inventory, sensor and bracket condition, glass and repair history 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 tyres and alignment, diagnostic scan, calibration record 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
Preserve the inspection sequence, ambient conditions and instrument evidence so the result can be reviewed later. A warm engine cannot stand in for a requested cold start, and a clean dashboard cannot replace a full-module scan. Link paint readings, underside images, service documents and road-test observations to the VIN. Separate confirmed defects from symptoms requiring diagnosis, then state whether each item means accept, repair, investigate or reject.
Read the record as if the original salesperson were unavailable. The conclusion about exact system inventory, sensor and bracket condition, glass and repair history, tyres and alignment, diagnostic scan, calibration record 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 every Tiguan have the same ADAS?
No. Equipment varies by generation, market and trim.
Is no warning lamp sufficient?
No. Physical inspection, diagnostics and calibration evidence are needed.
Can ADAS replace the driver?
No. The driver remains responsible.
