Dialogys and its numbering
Renault numbers are ten digits, usually written in groups — 8200 123 456. The leading block indicates the era and family of the number rather than the assembly group, which means a Renault number is less self-describing than a BMW or VAG one and the diagram carries more of the weight.
Dialogys is more than a parts catalog: it also carries labour times and service documentation, which is why a workshop quoting a job from it is working from the manufacturer's own figures rather than an estimate.
Renault and Dacia on one catalog
Dacia models are built on Renault platforms, and on shared components the number is the same for both. A Duster and a Captur can take one part under one number, which makes a single catalog the practical way to work on either.
The difference between the badges is mostly equipment level and market specification rather than mechanical architecture — and both of those are in the build record the VIN resolves.
Engine families drive the splits
Renault's parts splits follow the engine and gearbox codes closely: the dCi diesels and the TCe petrols each span several variants with different service parts, and the same nominal engine can differ by emissions standard across build dates.
Commercial models — Kangoo, Trafic, Master — add the usual van variables of wheelbase, roof height and weight rating on top, all of which the VIN carries.
Common Renault nameplates
These nameplates help you find the right vehicle family. Confirm the exact model, market and production period against the active catalog before quoting a part:
| Model | Production years |
|---|---|
| Renault Clio | 2019–present |
| Renault Megane | 2016–present |
| Renault Captur | 2019–present |
| Renault Duster | 2018–present |
| Renault Kangoo | — |
| Renault Trafic | — |
Frequently asked questions
What is Dialogys?
Renault Group's official electronic parts catalog, covering Renault and Dacia. It also carries labour times and service documentation alongside the parts data.
Does Dialogys cover Dacia?
Yes. Renault and Dacia are catalogued together, and on shared platforms they share part numbers.
How is a Renault part number structured?
Ten digits, usually written in groups such as 8200 123 456. The leading block identifies the number family rather than the assembly group, so the diagram does more of the identifying work.
