For car enthusiasts and DIYers in the UK, an OBD2 scanner is an invaluable tool. But with so many options on the market, finding the best DIY OBD2 scanner can be overwhelming. Are they all the same, or are some better than others for home use? Based on real user experiences and recommendations, we delve into the world of OBD2 scanners to help you choose the right one for your needs.
What to Look for in a DIY OBD2 Scanner
The original forum discussion highlights a few key considerations when selecting an OBD2 scanner for DIY car maintenance in the UK. Users are looking for tools that are user-friendly, reliable, and offer good value for money without necessarily breaking the bank. Here are some factors to consider:
- Vehicle Compatibility: Some scanners are brand-specific, like OBD Eleven and VCDS which are popular for VAG (Volkswagen Audi Group) vehicles, and Bimmerlink for BMW. Others, like Thinkdiag and Topdon Artidiag 500s, offer broader multi-brand compatibility. Consider the make and model of your car and whether you need a scanner for multiple vehicles.
- Functionality: Basic OBD2 scanners can read and clear generic fault codes, which is often sufficient for simple diagnostics like resetting an engine warning light. More advanced scanners offer deeper diagnostics, access to specific control modules, live data, and even coding/programming capabilities. Determine what level of functionality you require for your DIY repairs.
- Ease of Use: For DIYers, a scanner should be easy to use and understand. Many users appreciate smartphone-based apps like Torque Pro and Carista for their intuitive interfaces. Dedicated handheld scanners like Topdon Artidiag 500s are also popular for their ease of use and portability.
- Subscription vs. One-Off Cost: Some scanners, like OBDEleven and Thinkdiag, operate on a subscription model, offering ongoing updates and access to advanced features. Others, like Carista (for basic OBD2 functionality with a suitable adapter) and Torque Pro (app purchase), involve a one-off purchase. Consider your budget and how frequently you plan to use the scanner.
- Price: Prices range from budget-friendly generic scanners on Amazon to more professional and expensive tools. The “cheapest Amazon gizmo” mentioned in the discussion can handle basic code reading and resetting, proving that you don’t always need to spend a fortune.

Based on the forum discussion, here are some of the top OBD2 scanners recommended by UK car owners for DIY use:
-
OBDEleven: Highly praised for VAG vehicles (VW, Audi, Skoda, SEAT), OBDEleven offers advanced diagnostics, coding, and adaptations. It’s now also expanding to BMW. While it often requires a subscription for full functionality, users find it “exceptional” for in-depth work on VAG cars.

Choosing the Right OBD2 Scanner for You
The “best” DIY OBD2 scanner ultimately depends on your specific needs and budget. If you primarily work on VAG vehicles and want advanced capabilities, OBDEleven or VCDS are excellent choices.

If you need a user-friendly and affordable option for basic diagnostics and customization, Carista or Torque Pro offer great value.
Before making a purchase, consider:
- The make and model of your car(s).
- Your budget.
- The level of diagnostic capability you require.
- Whether you prefer a subscription-based or one-off purchase.
- Ease of use and user interface.
