Proud to work with industry leading partners
WrenchLane expands OEM data offering with Europe’s top OEM data supplier Infopro Digital Automotive
AI diagnostics + OEM data = WrenchLane
-
Manufacturer data, every make and model
Manufacturer specs and procedures for the European fleet, ready for whatever rolls into the bay. Techs stop switching between systems to find what they need.
-
Fluids and lubricants in one click
The specs techs use every day — engine oil, coolant, brake fluid — surfaced in a dropdown. No more digging through manuals to confirm the right grade.
-
Powered by trusted OEM data providers
Through our partnership with Infopro Digital Automotive, deeper OEM data sits inside the WrenchLane workflow.
-
Full image overview, find the part, then fix it
Components and procedures come illustrated, so techs can locate the part and follow the steps without second-guessing the description.
-
Every repair on one job sheet
Add fluids, parts, and labour to a single job sheet as you work the vehicle. Nothing slips, and the RO writes itself.
-
Time estimates that match the work
Get labour times for each repair, then watch them adjust when you bundle jobs that share teardown. Quotes reflect actual hours, not double-counted ones.

OEM Service Selector

How it works
Diagnose smarter and faster
Most diagnostic tools show fault codes in isolation, forcing technicians to rely on experience and guesswork to find the real cause. WrenchLane connects the dots. By analyzing multiple DTCs together with symptoms, real repair outcomes and OEM repair logic, WrenchLane identifies the most likely root cause — and guides you step by step through the repair.

How WrenchLane works
A simple workflow that fits how workshops already diagnose cars.
-
Step 1
Enter multiple fault codes or describe the problem
Add DTC codes, symptoms, or a short description of the issue — just like you would explain it to a colleague.
-
Step 2
Get a clear diagnostic direction to follow
WrenchLane analyzes fault codes together with symptoms and real repair data to surface the most likely root cause.
-
Step 3
Fix it right the first time with OEM guidelines
Follow a structured diagnostic path instead of guessing, reducing misdiagnoses and unnecessary part replacements.
Why workshops switch to WrenchLane
Built for workshops that want faster diagnostics, guided repairs, fewer comebacks and better margins.
- 7x
- Faster diagnosis
- 42%
- Fewer comebacks
- 20%
- Increased revenue
Built for real-world diagnostics and repairs, not just fault code lookups
WrenchLane goes beyond traditional diagnostic tools by analyzing how faults relate to each other across real repairs. Instead of treating DTCs as isolated issues, the platform helps workshops identify the true root cause and guides the repair accordingly. Just like experienced mechanics do, only faster and more consistent.
And when the fix needs a factory tool
Some repairs are not finished when the part is fitted. A new control unit arrives blank, a headlamp module has to be written to the car, an injector needs teaching in. Our partner AutoRemote connects to the vehicle and carries that out remotely, while the car stays on your lift, so the job stays in your workshop instead of going to the dealer.
Software updates, component programming, adaptation and teach-in. AutoRemote is responsible for the service, the hardware and the invoice, and charges per completed job.

A good complement on the workshop floor
We were a bit reluctant about the introduction of AI in troubleshooting cases. But WrenchLane has proven our concerns wrong. Everything from coming up with concrete suggestions when troubleshooting to measurement values and labour times for different jobs. We have tested fault codes that we know the answer to, and there WrenchLane is right a surprisingly high percentage of the time. WrenchLane has been a very good tool for the mechanic if you get stuck or need to find other angles. It has also helped the customer reception with times and repair instructions. WrenchLane is a good aid for the workshop.

A positive and instructive tool for technicians of all levels.
AI model is well versed in vehicle diagnosing and helping technician pinpoint and troubleshoot failures. Frequent updates help develop and improve UI. Search database is strong and feature friendly, including videos, schematics and forum searches but not limited to your basic Google search of an issue. Overall the software is a helpful tool for those who need help learning how to troubleshoot a car for the first time or those seasoned technicians who might have missed something during their diagnosis.

WrenchLane is the best repair program!
I came across the WrenchLane website by chance and was immediately impressed, and with this company the value for money is right! It is very clearly laid out and when there are problems, the support helps right away! Let’s be honest, which small workshop wants to spend 1,700.00 EUR on repair programs like Alldata? I have now been able to test WrenchLane long enough and it is much better than other repair programs. Anyone who keeps paying a lot for other programs has only themselves to blame. If I could, I would give WrenchLane 100 stars. Once again many thanks to WrenchLane and the good support.

It has already saved us both time and unnecessary parts replacements.
Really good for diagnostics and troubleshooting, recommended for all automotive workshops. WrenchLane provides fast, clear guidance and helps us move forward immediately when we get stuck. An extra plus is that everything is gathered in one place: fault codes, concrete troubleshooting steps, and relevant TSBs. It has already saved us both time and unnecessary parts replacements.

What great help
Used it to understand fault codes on my Audi. I also got instructions on how to continue troubleshooting, along with the part number of the component that was most likely faulty. I ordered the sensor it suggested and replaced it, and now the fault codes are gone.
