Proven diagnostics modules, lifted into the cloud

How Lynk & Co builds new diagnostic services on licensed DiagStudio modules — UDS, DoIP, VCI and software over the air — serving Lynk & Co and Lotus.

In brief

  1. 01 · Technical

    DiagStudio software modules reused into the cloud, with unified diagnostic services, diagnostics over internet protocol, vehicle communication interface and software over the air.

  2. 02 · Business

    A faster route to new diagnostic services: license and reuse proven DiagStudio modules instead of writing the diagnostics core from scratch — one core now serving two Geely-family brands.

  3. 03 · Lifecycle

    Connected-car diagnostics built on the same verified foundations that already run workshop systems — one discipline from bench to cloud, now in ongoing production maintenance.

How Lynk & Co builds new diagnostic services on licensed, reused DiagStudio functionality — UDS, DoIP, VCI and software over the air — serving both Lynk & Co and Lotus.

A Diadrom development team, together with a licence to reuse functionality from Diadrom DiagStudio, develops new diagnostic services with Lynk & Co: software modules reused into the cloud, unified diagnostic services and diagnostics over internet protocol, vehicle communication interface and software over the air. The services serve both Lynk & Co and Lotus, and the engagement continues today with Diadrom maintaining them in production.

The connected car moves diagnostics off the bench

The rising importance of on- and off-board software for connected and autonomous vehicles changes where diagnostics happens. It is no longer only a workshop activity over a cable: it is a cloud service, reaching the vehicle over the internet, updating software over the air. The OEMs that move fastest are the ones that do not rebuild their diagnostics foundations to get there.

Lynk & Co

Lynk & Co develops connected mobility within the Geely family — vehicles where the digital service experience is as much the product as the car itself. New diagnostic services are part of that promise: knowing the state of the vehicle, tracing faults and delivering software wherever the car is.

New services, without a new core

Building cloud-based diagnostic services from scratch means re-solving problems that proven workshop diagnostics already solved: vehicle communication, unified diagnostic services, safe software delivery. The faster route is to reuse a verified core — if the supplier’s product is engineered so its functionality can be licensed and lifted into a new context.

A team and a licence

The engagement combines a Diadrom development team with a licence fee for the right to reuse functionality of Diadrom DiagStudio, developing new diagnostic services together with Lynk & Co. Concretely: DiagStudio software modules reused into the cloud; unified diagnostic services and diagnostics over internet protocol (DoIP); vehicle communication interface (VCI); and software over the air (SOTA). The services built on this core serve both Lynk & Co and Lotus, and the engagement continues today, with Diadrom maintaining them in production.

For the engineers in the room

  • Engagement: Development team + licence fee for the right to reuse DiagStudio functionality — ongoing, now in production maintenance
  • Reuse: DiagStudio software modules reused into the cloud
  • Protocols: Unified diagnostic services (UDS) · diagnostics over internet protocol (DoIP)
  • Delivery: Vehicle communication interface (VCI) · software over the air (SOTA)
  • Serves: Lynk & Co and Lotus (Geely family)

What it changed

The Lynk & Co engagement proves the reuse model that defines Diadrom’s product thinking: diagnostics functionality engineered once, verified hard, then licensed into new contexts — from workshop client to cloud service, and from one brand to two, with the same core now serving both Lynk & Co and Lotus. For the customer it compresses time-to-service; for the industry it shows that the connected car does not need a new diagnostics core, it needs a proven one with an API.

“The licence is the headline for us: when a customer pays to reuse your modules in their cloud, your product architecture has passed its hardest review.”

— Viktor Eliasson, CEO, Diadrom

Advice to peers

Software over the air and internet-protocol diagnostics are becoming the default delivery path for the software-defined vehicle. The module-reuse model scales with it — the same verified diagnostics core, surfacing wherever the vehicle’s software lifecycle needs it.
