The unit reads codes and clears codes as needed, but when I perform basic "special functions" I keep getting communication errors or "Vehicle is not supported". I tried to update the device and got nowhere. I click refresh and it just says wait a minute. Half an hour. no update Nothing special. I have a 2001 325i (E46). *** REVIEW UPDATE *** The seller contacted me and was very polite and eager to fix the problem. I received a full refund and as I said the seller was very polite and easy to deal with in this situation.
