What to look for
- Every petrol car sold in the UK since 2001 (and diesel since 2004) has an OBD2 port.
- Enhanced codes for ABS, airbags and transmissions need a more capable scanner.
- Check for subscriptions: some cheap sensors lock key features behind monthly plans.
- Emissions readiness data helps before a state smog or inspection appointment.
How much to spend
Typical prices run from £18 to £109. Budget models cover the basics; spending more usually buys phone-based scanner with repair reports and no subscription. Only pay for features you will use.
Who should skip what
- Skip the BlueDriver Bluetooth Pro OBDII Scan Tool if you want a standalone handheld with its own screen
- Skip the FOXWELL NT301 OBD2 Scanner if you need ABS, airbag or transmission codes
- Skip the ANCEL AD310 Classic Enhanced if you want live data graphs, ABS or airbag codes, or repair guidance
Buying tips
Auto parts stores like AutoZone and O’Reilly will often read codes free, so a scanner pays off if you like to fix things yourself. Scanners go on sale on Prime Day and Black Friday.

Frequently asked questions
Can an OBD2 scanner tell me what is wrong?
It gives you codes and data that point to a system. Good apps suggest likely fixes, but a code is a starting point, not a final diagnosis.
Is it OK to clear a check engine light?
Clearing hides the problem; it does not fix it. Clear codes only after a repair, and note that clearing also resets emissions readiness.
Will a scanner work on my car?
Almost every petrol car from 2001 and diesel from 2004 in the UK is covered for engine codes. Enhanced coverage varies by brand.
