Hello everyone. As a result of asking a master, who is familiar in the forum or industry, I got advice about having cars with OBD and I learned that the car did not burn the FAULT LAMP easily when it was obd, so this piece is so that the malfunction lamp does not light up but financially OBD is a bit expensive. I heard positive things about Zavoli and I definitely decided to get it on, says 1.650, who is obdless on his site. My question is, if I get it without OBD, what problems do I have or if I don't have OBD? Or what would your suggestions be?
