Which OBD-II adapter do I need?

A Bluetooth LE or Wi-Fi ELM327 adapter, such as OBDLink CX or MX+, Vgate vLinker or Veepeak BLE. iPhones can't connect to older "classic Bluetooth" adapters.

The scanner won't connect

Turn the ignition on, check Bluetooth is on and that Diag Drive has Bluetooth permission (Settings › Diag Drive). For Wi-Fi adapters, join the adapter's Wi-Fi network first. You can try the scanner without a car using Scanner › Try demo.

How do AI credits work?

Restore or cancel a subscription

Tap Settings › Restore purchases in the app. To cancel on iPhone, open Settings › Apple ID › Subscriptions. On Android, open the Google Play Store › Profile › Payments & subscriptions › Subscriptions.

Delete my account

You can delete your Diag Drive account and its data at any time:

• In the app (iPhone or Android): go to Settings › Account › Delete account.
• Without the app: email support@motorlane.uk from the email address on your account (or tell us the email you signed in with) and ask us to delete it. We'll confirm and delete it within 30 days.

Deleting your account removes your account details, your synced garage (vehicles, service history, reminders), chat history and remaining credits from our servers. Records of purchases may be kept where the law requires it. Cancel any subscription in the App Store or Google Play as well, as deleting the account doesn't stop it. See our privacy policy for what we store.
