A clear dashboard cannot prove that every Tayron assistance sensor is correctly installed, aimed and calibrated.
Decision boundary
Identify the fitted assistance package and define which glass, bumper, body, wheel or suspension work creates a calibration or function-test requirement. If front glass has been replaced, review the windscreen installation and camera verification.
Continue the evidence route: Identify equipment in the software and ADAS guide, trace related repairs through the accident and flood route, and keep alignment evidence with the rolling-assembly check.
Evidence register
Inspect sensor part and mounting, windscreen and bumper identity, wheel alignment, module faults, calibration procedure, technician record and controlled test.
Where the risk sits
Equipment names vary by market and year, while unsuitable glass, repaired brackets or changed ride geometry can leave plausible but inaccurate sensor operation.
Candidate scenario
A windscreen replacement with a complete scan and calibration file is stronger evidence than an unrecorded original-looking screen with intermittent assistance faults.
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 equipment identity, camera glass, radar mounting before commercial acceptance. Keep wheel alignment, calibration record, controlled function test 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.
Compare candidates on identical columns
Use the same headings for equipment identity, camera glass, radar mounting, wheel alignment, calibration record, controlled function test. A blank means unknown, not absent, zero or passed. Add the source and evidence date beside each value, and exclude unverified equipment from valuation. The stronger Tayron is the one that satisfies the destination task with traceable evidence and manageable complete cost.
Record what can change before loading
Odometer, warning state, software, tyres, seller authority, quotation validity and carrier instructions can change after initial review. Name every item that needs rechecking before final payment and custody transfer. Preserve the earlier result as history instead of overwriting it, so a substitution or late change remains visible.
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 equipment identity, camera glass, radar mounting, wheel alignment, calibration record, controlled function test 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.

Volkswagen Newsroom: Tayron assistance-equipment context ↗Buyer questions
When should Tayron ADAS calibration be checked?
After relevant glass, bumper, sensor, body, steering or suspension work and whenever diagnostics or behaviour creates doubt.
Does calibration guarantee overseas feature support?
No. Hardware calibration and destination software or service availability are separate questions.
What closes the decision before payment?
A VIN-linked record of the relevant inspection, diagnosis, corrective work and repeat test, with remaining limits written into the contract file.
