Clutch Wear

Clutch wear, turned into a report the customer understands.

Read the clutch values off your diagnostic tester, type them in, and hand over a one-page report with one clear verdict. For the single-clutch automated manuals in Lamborghini, Audi R8 and Aston Martin cars, with the wear limits built in.

Coming soon to Google Play and the App Store.

How a job runs

  1. Read the tester. Put the car on the diagnostic tester and open the clutch measurement values for that model — the next section says exactly which ones.
  2. Type them in. Pick the model, enter the readings. The dial updates as you type, so a typo shows up immediately as a nonsense result.
  3. Add plate and technician. Scan or type the VIN if you want the car findable later.
  4. Print. The report is one page for the customer and the service advisor, and the job is saved to history at the same time.

Where the factory documents give a range for a reading, the app shows it under the field and turns the field red outside it, so a slipped digit is caught before it reaches a customer.

The app with a Lamborghini Gallardo MY04–08 selected and the two clutch position readings, Ch 19 and Ch 27, filled in.

Something to hand across the counter

One A4 page a service advisor can explain in a minute. The dial and a plain verdict at the top. Underneath, every reading that produced the number, the method, and lines for the technician and the service advisor to sign.

The page states the wear limit it was measured against, so another workshop can check the work. Print it, or save it as a PDF and send it.

A printed clutch wear report: 32% material left, plan the replacement, with the vehicle, the measured values and the method.

Supported cars

Each model has its own page in the user manual: where to read the values on the tester, how the wear is worked out, and the traps that catch people out.

Built into the app

The built-in guide open at the Lamborghini Gallardo MY04–08: control unit, where to read, and what each value is.

Where to read every value

Which control unit, which channel or measured value block, and what each line means, for every model. There is room to note the menu path on your own tester, so the next technician does not have to work it out again.

Read the user manual

Saved reports, each with its number plate, model, date and the percentage of material left.

Find the car again

Every report is saved on the phone and can be found by number plate, VIN, model or date. When the car comes back, you can show the customer how far the clutch has gone since the last visit.

Jobs can be backed up to a file before you change phone. Nothing is uploaded anywhere.

Free, and it stays that way

No purchase, no subscription, no advertising, no analytics. Everything is calculated on the phone, and the app makes no network connection at all: it works in a workshop basement with no signal, and nothing you type leaves the device.
