Features

See how AI diagnostics can help you save time

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

Diagnose smarter and faster

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.

  1. 01 / 04

    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.

  2. 02 / 04

    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.

  3. 03 / 04

    Check it on the car before you buy the part

    Every likely cause comes with the checks to run: where the component sits, what to measure and the value to expect.

  4. 04 / 04

    Fix it right the first time with OEM guidelines

    Follow a structured diagnostic path instead of guessing, reducing misdiagnoses and unnecessary part replacements.

Everything you need to diagnose with confidence

  • 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.

    Vehicle header: BMW X5 xDrive 25d, engine code B47D20B, 170 kW, diesel, 148,310 km, with the ask-anything bar and Chat, Wear parts, Fluids, Manuals, Electronics and OEM info
  • 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.

  • Repair guidance and context

    Follow structured diagnostic paths and OEM repair instructions based on real repair data and outcomes, presented in a clear, step-by-step workflow.

  • Wiring diagrams and fuses for the car in the bay

    Components, connectors and fuse maps for the exact vehicle, next to the diagnosis that sent you there.

  • TSB matching and bulletins

    Identify relevant service bulletins instantly based on fault codes, symptoms and vehicle.

  • OEM Service Selector

    Set the mileage or the age of the vehicle and WrenchLane will provide you with the correct service plan.

    Selected service: 30 minutes combined, with the mandatory task list for engine, brakes and electrics
  • 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.

    AI-written invoice text for a completed diagnosis: complaint, cause, action and labour time, with Edit and Copy

Electronics

From the fault code to the pin you measure.

Wiring diagrams, component locations and guided multimeter tests for the exact car: which pin, what to measure, the value to expect.

01

Find it

Where the component sits in the engine bay, drawn for this exact car.

Locate tab for the H11 boost pressure control motor: an engine-bay drawing with the component marked, and where it sits on the car

02

Measure it

The pin, the meter setting and the value to expect. Answer yes or no and move on.

Guided check 1 of 5: turn the ignition on and measure the voltage on pin 3, expected 0.1 V, answer Yes or No

03

Follow the wire

The wiring diagram for the component, connectors and pin numbers included.

Ask it like you would ask a colleague.

Torques, oil grades, what a code means on this engine. Answers come with their sources.

From the car in the bay to the invoice.

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.

The film

Every feature, in 10 minutes.

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.
