Price and rating as shown on Amazon when we collected them. Both change.
The KINGBOLEN EDIAG Elite sits at number 4 in this guide. It is a £80 Bluetooth dongle that plugs into the OBD port and turns an Android or iOS phone into the diagnostic display. Its pitch is unusually specific for the price: 15+ reset functions including oil, brake, ABS bleeding, BMS, DPF, EGR, throttle, suspension and SAS, plus bi-directional active tests, all with lifetime free update and no subscription.
That last part is where it stands apart from the other Bluetooth reader in this list, which the article notes is only subscription-free for the first year. This one puts "Lifetime Update" in the product name itself, and repeats it in the bullet points. It also carries 1,306 reviews at 4.3 out of 5, and ranks 30th in Amazon's OBD-II Engine System Diagnostic Tools category.
The listing's own specification table is where the numbers stop agreeing with the description. A tool that pairs to your phone over Bluetooth and has no cable in the box is listed with "Screen Size: 20 Centimetres" and "Power Source: Corded Electric". The bullet points describe a 5.20 Bluetooth connection and an app, not a screen and a mains lead. The same listing says the app is for phones and not tablets, while the customer reviews below report it working on a tablet as well. Everything on this page comes from the Amazon listing and its customer reviews, not from our own testing.
