I received my Tech2 from chinacardiags a couple a weeks ago. I noticed the DLC cable connector would not completely seat into the VCI connector. The cable connector has a molded boss that locks the VCI latching lever. I had to trim the boss on cable connector to clear the VCI latch.
Silver marker highlights trimmed corner on boss.
