Rank #3 in Best OBD2 Scanner 2026: 10 Ranked, and the Numbers That Don't Fit
TOPDON TopScan Lite Bluetooth OBD2 Scanner
Price and rating as shown on Amazon when we collected them. Both change.
Of the two Bluetooth readers in this guide, the TOPDON TopScan Lite is the cheaper at £55.92. It is a plug-in dongle that pairs with a phone rather than a handset with its own screen: the listing's included components are given as one "TOPSCAN code reader bluetooth", the operating system is Android and iOS, and the Bluetooth pairing is completed inside the app, named as TopGuru for iOS users and TopScan for Android. It takes third place in our top ten, and Amazon ranks it 7th in OBD-II Engine System Diagnostic Tools and 721st in Automotive overall.
The number to read carefully is the subscription. The headline position is that the TOPDON is free to subscribe for the first year — the same bullet then says there are "2 subscription optioins", before listing three of them: monthly, quarterly or yearly. The spec table also gives "Power Source: Bluetooth", which describes how the unit connects rather than what powers it. On ratings, the 4.2 average from 3,040 ratings hides a split: 68% of the rating breakdown is 5-star, and 10% is 1-star. Everything on this page comes from the Amazon listing for this product, not from our own testing.
