  1. Purchased today,read instruction manual,which had at least 4 spelling errors.Hope that no more important information errors.looking forward to using this unit. Thanks.

  2. kw808 can not be up dated and can not print there is no usb port on here

  3. absolute piece of crap, avoid at all costs, tried on three different cars, Mercedes e 320cdi, jaguar xk8 and Vauxhall astra 1.4 turbo, showed one code on all of them on first screen but none further on in current codes. none of the other functions worked on any of the cars even though listed as been able to connect.

    • Konnwei KW808 don’t mention clearly which brand/model actually this scanner support. I tested this tool my Ford R7 and Jaguar XE. It worked on Ford R7 but didn’t work Jaguar XE. I have mentioned this in my article setback area. However, I didn’t expect much from a $40 scanner. I will suggest, check this article scanners list https://theeffectiveguide.com/best-obd2-scanner/ and buy one of them. I didn’t get negative feedback from those scanners.

  4. Is there anybody who could help me how to start new Diagnostics on my KW808 scan tester? Every time I want to start new Diagnostics in Main Menu the following window will appear saying “Erase previously stored data to save data from this test?” If I ENTER YES shortly after will appear System Status for a very short period of time and after that, it jumps to Diagnostic Menu on the first item Read Codes. In other words if I enter yes, the previously stored data will do be erased and it makes me impossible to continue further with the test. Once again, how to erase all data before starting performing so that it allows me to perform a new diagnostic test. Thanks

  5. I bought a KW808 and can’t get it to read live data on my 2002 Kia Rio. Any ideas. Can it be upgraded on internet? All inputs will be appreciated. Mike

    • Yes, you can update via Internet.

  6. how do you upgrade konwei kw808 over internetbif it does not have usb support?
