Review on MUCAR CDL20 OBD2 Scanner - Check Engine Code Reader And Diagnostic Scan Tool For All OBD II Protocol Cars Since 1996, With O2 Sensor, EVAP System, And Smog Test Functions by Chris Hodges

Now and then we all get to see the check engine light. A light designed to put terror into you. You drive to a garage, they do some magic, give you a quote, and fix it.But was the quote right? Well, this will not tell you how much a repair will cost, but it will tell you exactly what the problem is. And for many issues, it will let you switch off the warning light (do use this with caution, switching off the light does not switch off the problem!).This small unit works very well. Some of the menus are a bit frustrating to work through, but most users won’t be accessing the more advanced features. Its strong, easy to clean, small, and easy to keep in your car. If you have a car that is more than 8 years old, you need this. Less than 8 years, this is still a great tool to have.
