Checked on 12 Nov 2026. Written by the WrenchLane team. WrenchLane licenses HaynesPro data from Infopro Digital Automotive for European cars, so HaynesPro is our data partner, not a competitor. That is also why this page has no HaynesPro prices: they are set by each distributor, and we leave them to them.
HaynesPro by Infopro Digital Automotive is one of the most widely used repair-data libraries in Europe. Many workshops ask us the same two questions: how do I actually buy it, and what does an AI tool add if I already have it? This guide answers both.
Who makes HaynesPro
HaynesPro WorkshopData comes from HaynesPro BV in Nieuwegein, the Netherlands. It is part of Infopro Digital Automotive, the group that also owns ETAI and Atelio in France and Isi Condal in Spain [1]. It covers 27 languages and, according to HaynesPro, 99% of the European car parc [2].
What you can buy
WorkshopData is built from packages and editions, so two workshops with "HaynesPro" can have quite different content [2]:
- Editions: Car, Truck and Moto. Check that the edition matches the vehicles you actually repair.
- Tech: technical data such as adjustment values, maintenance schedules, repair times, procedures and lubricants.
- Electronics: wiring diagrams, component tests and fuse and relay locations, plus VESA, HaynesPro's guided diagnosis that takes stored fault codes.
- Smart: SmartFIX technical bulletins and SmartCASE, a collection of validated fixes from real repairs.
HaynesPro data is also built into many scan tools through an API, so you may already have part of it inside your diagnostic tester [2].
How the buying works
You cannot buy WorkshopData directly from HaynesPro as an end workshop. HaynesPro issues licences to its distributors through its licence system (VOLT), and the distributor sells to you [3]. In practice that means one of three routes:
- Your parts distributor. Large parts wholesalers in many countries sell HaynesPro licences, often with support in your language.
- A scan-tool dealer. Several tool makers bundle a HaynesPro module with their scan tool, usually for a year at a time.
- A workshop concept or chain. Some chains and workshop programmes include HaynesPro for their members.
The usual model is an annual licence, per workshop or for a number of workstations [4]. The price is set by the distributor, so it differs by country, package and channel. The HaynesPro distributors page lists who sells it where [3].
What to ask your distributor
- Which edition and which packages (Tech, Electronics, Smart) are included?
- How many workstations or users does the licence cover?
- How long is the licence, and does it renew automatically?
- Which languages can your team use?
- Is it a standalone licence or tied to a scan tool, and what happens to it if you change tools?
What AI diagnosis adds on top
A library answers the question you ask it. The hard part of many jobs is knowing which question to ask, when a car comes in with four stored codes and a vague complaint.
That is the step WrenchLane adds. You get more with WrenchLane: HaynesPro data by Infopro plus AI diagnosis on top. You type the fault codes and the symptoms, or take a photo of your scan tool screen, and WrenchLane ranks the likely causes for that car and lists the checks that confirm or rule out each one. When a check needs a value, a pin table or a procedure, it comes from licensed HaynesPro data by Infopro: adjustment values with tolerances, lubricants and capacities, repair procedures with special tools, repair times, component tests, pin tables with wire colours and warning lights.
To be clear about what WrenchLane is and is not:
- WrenchLane licenses a selection of HaynesPro data, not the whole WorkshopData product. Truck and Moto editions, VESA and SmartCASE stay with a HaynesPro licence.
- WrenchLane is not a scan tool. It does no bi-directional control or coding. It works with the scan tool you already own.
- If you need the full library, buy HaynesPro by Infopro through your distributor. If you also want help getting from codes to a likely cause, add WrenchLane on top. Many workshops use both.
WrenchLane Small costs €69 per month (749 kr in Sweden, 299 zł in Poland), monthly, cancel any time, one plan for the whole workshop (wrenchlane.com/pricing, 12 Nov 2026).
