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 the team behind HaynesPro, OATS and DriveRightData, 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.

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.

What mechanics say

Hear from shops using WrenchLane

"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."

"We primarily use WrenchLane to troubleshoot complex diagnostics where there are multiple fault codes and an unknown root cause. It’s an effective way to validate different scenarios and significantly reduce troubleshooting time."
Kamil
Bilverkstad i Nacka AB , Stockhom Sweden
"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."
Anders Levin
