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.Most diagnostic tools show fault codes in isolation — leaving technicians to guess the root 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

What mechanics say

Hear from shops using WrenchLane

"I tested the service to understand some fault codes on the car. I received a diagnosis that helped me confirm the problem. It worked well and was fairly quick."
Jacob Qvisth
Personal user, Stockholm
"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 , Nacka
"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
Levin Racing, Kungsör
