Twenty-five yearsof aftermarket tools,one modern platform
Introduction
01A vehicle spends almost all of its life in the aftermarket, and the platform that diagnoses it decides how fast a workshop turns a fault into a fix. Replacing that platform is not a rewrite — it is a migration that has to happen while the world's workshops keep working.
Volvo Group's Aftermarket Tool is the application a workshop reaches for, anywhere in the world, to find out what is wrong with a vehicle and put it right. It is proven — and it is a 'fat' PC client, monolithic and built for a local, workshop-only world. Volvo Group Digital & IT set out to replace it with a modern, modularised ecosystem: a service platform that carries multiple end-user applications, serves both remote and workshop scenarios, and puts all the Group's brands on one diagnostics foundation.
Diadrom has worked in Volvo Group's central IT systems and aftermarket tools since 1999. That quarter-century in the Group's diagnostics domain is what makes the migration a continuation rather than a restart: the team supporting Digital & IT works in the core of the new platform, not alongside it.
Diadrom has always supplied high skilled consultants, with a great attitude, and profound knowledge of the business. The 'getting things done' attitude of Diadrom is impressive.
Impact
02Continuity,not a restart
The risk in replacing a legacy toolchain is not writing the new one. It is losing the accumulated domain knowledge that tells you which of its behaviours were deliberate — and every workshop day that the migration cannot afford to interrupt.

Capabilities
03One foundation, every brand and every market
The platform has to do what the fat client did, for every Group brand worldwide — and then do it again for scenarios the fat client was never built to reach.
- 01Unified diagnostic services (UDS) as a platform service
- 02Software download to the vehicle
- 03Fault tracing and troubleshooting
- 04Multiple end-user applications on one service platform
- 05Workshop and remote scenarios from the same diagnostics core
- 06All Volvo Group brands, in every market they serve
The system
04Insidethe migration
From fat client to service platform
- A monolithic PC client decomposed into services that end-user applications consume
- Diagnostics logic moved out of the client and into the platform, where every brand can reach it
In practice
- Add a new end-user application without reimplementing the diagnostics underneath it
- Change a diagnostic service once instead of once per brand-specific build
Core functions
- Unified diagnostic services
- Software download
- Fault tracing
- Troubleshooting
The workshop and the connected vehicle
- One diagnostics core serving both the technician in the bay and the remote scenario
- A foundation built to absorb the shift as more fixes begin before the vehicle arrives
In practice
- Serve a local, technician-operated session and a connected remote session from the same services
- Raise what the tool does as the mechanic's job grows more demanding, rather than replacing the tool again
Scenarios
- Workshop
- Remote
- Connected vehicle
- Over-the-air
A team inside the process
- More than ten Diadrom system developers integrated with Volvo Group Digital & IT
- Domain knowledge applied at design time, not recovered afterwards from the legacy code
In practice
- Carry the reasoning behind two decades of tooling decisions into the new architecture
- Keep the migration running while the existing client stays in daily service worldwide
Engagement model
- Long-term team
- Inside the customer's process
- Design-phase involvement
Heritage
- Volvo Group central IT since 1999
- Aftermarket tools
- Cross-brand
Outcome
05Built to absorbwhat comes next
By modularising the toolchain, Volvo Group gets a foundation that serves today's workshop bay and tomorrow's remote scenario from the same diagnostics core — one platform behind every brand, in every market, instead of a client that has to be rebuilt each time the world moves.
The direction is set by the connected vehicle: more remote diagnostics, more over-the-air capability, and a growing share of fixes that begin before the vehicle reaches the workshop. The platform is built to absorb that shift — and Diadrom's quarter-century in the Group's diagnostics domain is what turned the migration into a continuation.
You cannot modernise two decades of aftermarket tooling from the outside. It takes a team that already knows where the bodies are buried — and stays until the new platform carries the load.
