FAQ

The ADL H4 scan reveals electronic faults, codes, live data and system statuses. It helps identify likely issues but does not replace a full mechanical inspection for wear-and-tear components.

Typical onsite scans take 20–40 minutes. Comprehensive checks with road testing may take up to 60 minutes.

We do not clear codes during a pre-purchase scan unless requested. Clearing codes hides the vehicle history and is not recommended for buyers.
