Accessory acceptance should check both the installation quality and the impact on the whole vehicle. Wiring that conducts and functions that work only show that part of the verification is complete; the applicable boundaries of the original warranty and Peru's technical inspection still need to be confirmed separately.
Preserve the Original Vehicle State before Installation
For a Volkswagen Tiguan L, record the original configuration, installation positions, part models and the contractor. Changes involving load-bearing, electrical or safety systems should be assessed by staff with the appropriate capability; compatibility cannot be inferred from the model webpage, and no performance gains after modification may be promised.
The installation task can attach photos of the original vehicle, the use stated by the customer and the materials for the parts to be used. The reception staff confirm the customer's expectation, the installer states whether the work can be taken on, and the technical lead checks what fitment evidence is still needed. Photos provided by the customer count only as intent materials and are not written directly into a confirmed work plan.
Before the work starts, it is advisable to determine which original parts need to be kept, who receives them after removal, and how unauthorized items are handled. When checks involve electrical or safety areas, only people with the corresponding capability decide the work arrangements; sales does not add operating instructions to the site. If materials are insufficient, keep the item in a pending-assessment state rather than filling it in with generic installation experience.
Sign Acceptance Separately
| Acceptance item | Who provides the basis | What to do when it is missing |
|---|---|---|
| Part identity and fitment | Supplier | Stop using the unidentified part |
| Installation quality and function | Installer and inspector | Record rework by issue |
| Inspection and warranty impact | Local professionals and responsible parties | Confirm in writing before deciding on delivery |
Acceptance can collect signed opinions separately for part receipt, installation records and the whole-vehicle check. If a part's identity is unclear, return it to the supplier for verification; if the installation's appearance or function is in doubt, the contractor explains. For answers involving inspection and warranty, keep who issued them and their scope of application; do not turn a phone summary into unconditional approval.
When the customer asks to keep unresolved issues, first ask the person responsible for technical judgment whether the vehicle can be returned to them. State separately the delivery conditions that can be offered and the matters still to be handled. Additional costs, rework arrangements and the whereabouts of original parts are registered according to the actual agreement; the customer must not be left guessing the scope of responsibility only after installation is complete.
Do Not Let the Delivery Checklist Miss the Changes
HSE materials are a reference for repair risks, and the MTC portal is used for local inspection checks; neither is an approval of this modification. Give the customer the actual accessory items fitted and the maintenance precautions, and record where the original parts and the removed parts went.
What Still Needs Checking after Returning to the Original Configuration
Example, subject to the contract and the actual vehicle. The accessory fitment on one VIN was not accepted by the customer, and both sides discussed restoring the original configuration. The installer can first propose a removal plan, stating the original areas that need checking and the materials to keep, and the work proceeds only after the corresponding confirmations are obtained. The receiving person checks against the pre-installation records and refers any changes to the technical lead for review.
It is advisable to keep separate evidence for the removal, the re-check and the explanation to the customer. Items that remain unclear after the appearance is restored are still marked; the matter cannot end just because the original parts have been refitted. The delivery materials keep the work process that occurred and state which maintenance instructions currently apply, so that later service staff can find the modification history.
FAQ
Does a part specified by the customer exempt acceptance?
No. The installation responsibility and the customer's choice should be explained separately.
Does the original warranty definitely become void?
Check the affected scope with the responsible party; do not assert that it is either wholly valid or wholly void.
Is keeping only the installation invoice enough?
Part identity, work records and inspection results are also needed.
If it is returned to the original condition, can the vehicle be delivered directly?
The impact of the removal and reinstallation should be checked before the whole-vehicle condition is confirmed.
When discussing an accessory plan, provide the intended use of the part, the original vehicle version and the proposed installation method, and contact us through the Starvia contact page or WhatsApp.
