The Konwei OBD scanner is a substantial piece of kit measuring approx 200X100mm. It feels well made and comes in a strong zip case with a useful instruction booklet. After servicing our Nissan Note the dreaded engine warning light appeared. Thought I knew the cause and the Konwei was able to read the error code and confirm the diagnosis. When the engine management system did not reset itself automatically I was able to delete the error code and remove the warning light. Easily paid for itself compared to a visit to a mechanic and will be useful in the future no doubt. Follow the warnings in the instruction booklet and don't remove error codes immediately before going for an M.O.T because the emission control software may need time to gather readings and set itself prior to the test. These functions can be checked with the Konwei.Read full review

Useful tool at a useful price. Gets rid of engine management light. Easy to use. Down side; it has a print option that doesn’t actually work. I’ve searched the internet for a usb cable to plug it into my pc but one doesn’t seem to exist.

This product extracts more information than I actually need, it is robust and easy to use, it turns off error messages and resets them, not the Volvo specific ones unfortunately, airbag and service are not included but for the price it is a valuable tool

This product is extremely well put together and the equipment "does what it says on the box", however unfortunately not on my vehicle but on my friends identical vehicle. It appears I have a fault somewhere in the electrics but this in no way detracts from the equipment.

Whilst it would not give vehicle VIN info, or show specific Citroen fault codes, it did provide some very useful information and gave real-time readouts of temperatures, pressures, rpm, ignition timing, etc. Liked the emission readouts and the general solidity of the unit. Well worth the money and a useful addition to anybody's toolkit
