LNVI Product System
Our in-house method

The LNVI Product System©

Repairing is a trade. Doing it with method is the proof.

In many workshops, every repair is improvised. At LNVI, every vehicle follows a documented industrial process, from reception to return. We drew inspiration from Japanese industrial excellence — the rigour of a production line — and applied it to trucks and vans.

"LNVI Product System" is the name of our internal method, specific to LNVI — an in-house workshop organisation, not a label or a certification issued by an outside body.

Two Japanese ideas,
applied to the workshop.

Kaizen — continuous improvement

Nothing is set in stone. Our methods, our standard times, our references evolve with every intervention. Each file feeds the next: the workshop keeps progressing.

Kensho — validation by proof

A diagnosis is not guessed, it is demonstrated: fault code, measurement, diagnostic tool report as evidence. And no vehicle leaves without an exit inspection.

The production line

Six steps. The same order, every time.

Every vehicle goes through the same stages — and each one produces a record added to its file.

01

Reception & admission

The vehicle enters the system: file opened, history reviewed, mileage and condition recorded. We check that recent work is not about to be redone for nothing.

Record: file opened, mileage & condition recorded
02

Diagnostics 検証 Kensho

Diagnostic tool readout, fault codes cross-checked with the driver's complaint, reception inspection. The cause is identified and documented — not assumed. The Bilan 360 applies this step →

Trace: fault codes & documented cause
03

Quote & written approval

Clear pricing based on manufacturer labour times, transparent, with no grey areas. Nothing starts without your signed approval.

Trace: itemised quote + signed approval
04

Repair

Work carried out to the highest professional standards, with original or quality equivalent parts and official labour times. Every operation is traced.

Trace: operations traced, parts referenced
05

Exit inspection

Road test, checks, restoration to compliance. The vehicle does not leave until it has been signed off.

Trace: workshop sign-off
06

Handover & proof

Detailed report backed by photos. You know exactly what was done, and why.

Trace: detailed report + photos
What it changes for you

You stay in control. We keep the trace.

No nasty surprises

Written approval before work, pricing based on manufacturer labour times.

One file per vehicle

History kept on record — your fleet followed over time.

The fault treated at its cause

Not the symptom: fewer return trips to the workshop.

A single point of contact

The same contact, from quote to handover.

Online tracking of your repairs

Report and photos at handover. Track my repair →
