TOPDONAL500 OBD2 Code Reader with Full OBD2 Functions, Universal Car Diagnostic Tool OBD Scanner for All Cars with 2.8＂TFT Display, Free Update, DTC Lookup, Print via PC, Built-in Help Menu, Black

Great item just what I wanted and at a good price

Easy to operate, sturdy. Already paid for itself by saving me a garage diagnostic visit.

Works fine on my 2006 Mercedes CLK 220 for picking up the fault and clearing it and the EMS warning light. Based on the fault code returned I traced the issue to a subtly split turbo hose.Many of the other features do not seem to work on this particular vehicle but it did what I bought it for so all good.

TOPDON Code Reader AL400 is the upgrade version of AL200/AL300.This OBD2 scanner comes with variety of OBD2 functions, including reading & erasing DTCs/resetting monitors/live streaming in graphs/viewing freeze frame data, and many more features that would usually be found in an expensive diagnostic tool. Determine the cause of "Check Engine" lights/monitor the running components of the engine, and use freeze-frame technology to focus on a car's trouble area. I replaced a sensor on my Campervan and used this to delete the DTC. It’s really straight forward to use and you can even use it in the dark due to the light built into the OBD plug. Comes with lifetime updates via a USB connection lead to connect to a computer so there’s no subscription to pay for which really appeals to me. This OBD2 reader is really easy to use, has loads of features, lifetime updates and a really great price! 💰👍

bought this just over 12 months ago . and i have a abs warning light on the dash .but the scanner fails to pick up any codes grr.maybe im unlucky or been given the wrong one .but they are getting very good reviews .i know have have a scanner which is of no use to me and out of warranty

Considering the price, a really good and fairly basic device. Bear in mind it is not strictly a diagnostic tool. It's a trouble code reader, eraser and "live" data viewer.Easy to update by visiting Topdon website and downloading the latest firmware April 2022 is the one that was available at the time of writing this. My Win 10 did disply a warning about downloading the update tool.Long, flexible cable and useful l.e.d. light incorporated into the plug. My car's OBD port is buried deep under the dash! No reference in the instructions about replacing the battery for the light. Probably a button cell and accessible by removing the small screws on the plug?Edited to add that there are two CR1220 cells in the plug. Without encouraging anyone to replace them, when necessary, they are easy to access with care. Doing so will probably invalidate any warranty though.Recommended for slightly more than very basic use.

If you know how to use it, good. I used it didn't know how to fix it, so had to return it.KNOW HOW TO FIX, NO POINT JUST BUYING

Really good code reader. Did have to add my car via the USB cable but no big issue.
