Professional vehicle diagnostics

Autel diagnostic equipment, used with realistic limits

Professional equipment gives access to far more vehicle systems and live data than a basic engine-code reader. The exact coverage still depends on the vehicle make, model, year, software and the function being requested.

What the equipment can help us investigate

Coverage is confirmed against your vehicle before any specialist programming or adaptation work is booked.

Full-system scanning

Engine, ABS, airbags, transmission, body control, parking, DPF and other available modules—not engine codes alone.

Live data

Sensor readings such as wheel speeds, temperatures, pressures, fuel trims and other supported values can be compared in real time.

Warning-light diagnosis

Fault codes and live readings help narrow down the cause and identify sensible next tests instead of guessing at parts.

Pre-purchase scans

Stored and current faults can reveal useful evidence before you commit to buying a car or van.

Service functions

Resets, adaptations and test routines may be available where the vehicle and equipment support them.

Selected key functions

Key or immobiliser work is limited to supported vehicles and must be agreed in advance with proof of ownership.

What a diagnostic visit gives you

Evidence

Fault codes, available module data and observations gathered during the booked visit.

Plain-English explanation

A clear description of what the results mean and which next step appears most sensible.

A report you can keep

A printed or emailed report where included in the agreed service, useful for your records or mechanic.

Important: no scanner is universal

A professional diagnostic tool is powerful, but it cannot guarantee access to every function on every vehicle or replace mechanical, electrical or manufacturer-specific testing. We do not promise that clearing a code will repair an active fault. Send the registration and symptoms first so the correct service can be agreed.
