Features
WrenchLane connects the dots between fault codes, symptoms, and real repair outcomes. Other tools show you a list. We show you the path.
How it works
Describe the symptoms and add the fault codes. WrenchLane helps you see how they connect, find the likely causes and know what to check first.
Add DTC codes, symptoms, or a short description of the issue, just like you would explain it to a colleague.
WrenchLane analyzes fault codes together with symptoms and real repair data to surface the most likely root cause.
Every likely cause comes with the checks to run: where the component sits, what to measure and the value to expect.
Follow a structured diagnostic path instead of guessing, reducing misdiagnoses and unnecessary part replacements.




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.
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.
Follow structured diagnostic paths and OEM repair instructions based on real repair data and outcomes, presented in a clear, step-by-step workflow.
Components, connectors and fuse maps for the exact vehicle, next to the diagnosis that sent you there.
Identify relevant service bulletins instantly based on fault codes, symptoms and vehicle.
Set the mileage or the age of the vehicle and WrenchLane will provide you with the correct service plan.
Add fluids, parts, and labour to a single job sheet as you work the vehicle. Nothing slips, and the RO writes itself.
Electronics
Wiring diagrams, component locations and guided multimeter tests for the exact car: which pin, what to measure, the value to expect.

Torques, oil grades, what a code means on this engine. Answers come with their sources.
Built for workshops that want faster diagnostics, guided repairs, fewer comebacks and better margins.
Find the car. Registration number or VIN, and the right model, engine and data load. Diagnostic, service, bulletins, manuals and wiring for that exact car, one click away.
Diagnose. Fault codes and symptoms in, ranked causes out. WrenchLane reads the codes together, the way an experienced mechanic would, and puts the most likely cause first.
Check. Guided tests confirm the cause before a part is ordered: where the component sits, what to measure and the value to expect.
Repair. OEM procedures, torques and labour times for the job, step by step, so the quote matches the work.
Invoice. Add fluids, parts and labour to a single job sheet as you work the vehicle. Nothing slips, and the invoice text writes itself.
What mechanics say
See every rating from the app“The integrated AI feature is a real game changer.”
The film

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.
