In short, as stated in other reviews, this reader works with essences from 2001 and diesel from 2004. Some manufacturers had already made their compatible vehicles before these dates so the only thing to do is to try and see.
Attention, this drive requires that contact be put to work. Otherwise you will have the message "link error" on the screen.
The manual is in English but the codes that the device gives are universal. Just type the fault code on google and you will find no problem what it is (in French). The reader is manufactured in China and the quality is not fantastic (orange shell is not terrible) but it does what I ask him. It is not as sharp as the suitcase of a dealer, do not expect to erase airbag fault eg. However, it will read the trouble-free engine defects.
For the price, it's honest. I amortized on first use.
