I ordered an ELM327 v1.5 scanner (version 1.5), as I studied this issue on the net in advance, and found out that newer versions (for example, v2.1) do not work with older cars. The announcement indicated that they were selling the version of V1.5, but they sent 2.1 N A D U L I. To paraphrase the tsar from the Soviet cartoon "the merchant's word is stronger than peas", so it's not entrepreneurs (merchants), but liars and deceivers who work in this store.
