This is a top of the line OBDII code reader, I purchased this one to try and figure out the issues i was having with my car but after a little more investigation I was able to solve the problem myself. (I sold the car haha) I already have a basic code reader and I don't need this, it is still in its box, unopened and it came highly recommended, it really is one of the best on the market. They retail at around £140 so grab a bargain. It does require an app and my go to would be "Torque lite/pro" but there are lots to choose from nowadays.
