Scanners for Louro on iPhone
Compare the listed models, see which readings are covered and check what still depends on your car. Start with the exact scanner, not the price.
Free download · Optional in-app purchases · A new scan needs supported hardware.
Before choosing a scanner
A scanner plugs into the scanner port, the small opening it connects to in your car. It needs the right hardware to reach the readings you want. An app cannot add a missing part inside the scanner.
OBD-II is the common system for reading engine and emissions information. Cars can share a plug shape and still provide different readings. Check your exact car and the systems you want to read.
Louro needs to support the reading too. A feature advertised for another app is not automatically available in Louro. A higher scanner price does not guarantee more features in your car.
What you can do in Louro
Start with supported readings, keep useful context and prepare better questions for a mechanic.
Read a supported engine fault code and ask Opie to explain it in everyday words. A code is a starting point; further checks may be needed to find the cause.
See supported live readings from your car while connected to a compatible scanner. Available readings depend on the car and scanner.
Keep supported scan information with the right car. Check the current app for the history available on your plan.
See whether the car has completed its built-in emissions checks, where supported. A completed check does not guarantee the car will pass a test.

Check the exact scanner version and your car before buying. Features marked “Not confirmed” need a separate check.

The OBDLink maker describes extra Ford and GM network access for MX+. That hardware capability does not prove Louro supports extra car systems. Check the maker’s MX+ information and vehicle guidance for its scope. Veepeak OBDCheck BLE and generic ELM327-type scanners are not verified with Louro on this page; a similar-looking case is not the same model.
Keep the car parked. Find the scanner port using your car’s guide, line up the shapes and plug in gently. Follow the car and scanner guides for when to turn the car on. Check the scanner’s power light. If the engine needs to run, keep the car outdoors.
Open iPhone Settings, choose Bluetooth and select OBDLink MX+. If it does not appear, press the scanner’s Pair button and look again. Then open Louro and connect your scanner. Follow the maker’s setup guide if you need help.
A connection has been reported for the pictured black-and-orange unit through iPhone Bluetooth settings, using a PIN. Check your unit’s guide for its name and PIN if asked. Other versions may connect inside Louro instead. Check that your unit matches before following the same steps.
Read the results carefully
Listed features depend on the scanner version, your car and the current Louro app. “Not confirmed” means you should check before buying, not that a feature has been proved to fail. Louro does not manufacture these scanners. Listing one does not mean approval by its maker or support for every car.
How a scan goes
A scanner port alone does not guarantee every reading is available. Check your car's guide and the scanner maker's vehicle information before buying.
The Louro scanners listed here connect by Bluetooth. A Bluetooth label alone does not prove iPhone or Louro support. Wi-Fi scanners are not supported by Louro.
Louro helps explain what the car reports. A code does not prove which part needs replacing. A qualified mechanic may need further tests.
Ask about a code you already have and start organizing your car’s information. A new physical scan needs supported hardware. Louro is free to download, with optional in-app purchases.
