Plug-in OBD2 code readers like this GOANDO scanner sit at the budget end of the diagnostic tool range, competing with basic units from brands such as Autel and Ancel. It is meant for quick checks when the check engine light comes on, letting you read fault codes yourself before paying for a garage visit, and clear codes after a fix (or to confirm whether a warning returns).

Who is this for?

Useful for everyday drivers who want a simple first step in fault-finding, especially on older cars where a single stored code can point you towards a common sensor or emissions issue. It is less suited to deeper troubleshooting, because low-cost readers typically focus on engine and emissions codes rather than manufacturer-specific systems like ABS, airbags, or service resets.

  • Reads and clears OBD2 codes, helping you understand why the engine light is on and reset it once the underlying issue is addressed.
  • Works across OBD2 protocols, so it should cover most petrol cars from 2001 and diesel cars from 2004 onwards in the UK.
