I have suspicious, that your car doesn't have OBD-II standart support.
Does OBD socket looks like OBD-II?

I just asking, because OBDuino32k support only OBD-II standart (ISO (9141-2) and ISO14230-4 (KWP2000); CAN - only with ELM327 chip).
Earlier in the cars was OBD-I standard and everyone producer used his own OBD-I implementation. For example, VW has 2 sockets with 4 wires.
If so, it's necessary to use
