OBD port not responding
Posted: Mon May 08, 2023 10:58 am
Hi, I picked up a 2016 2.0TDI SE Business Estate recently. The OBD port isn't responding, I don't believe there is power to it as the LED on my OBDEleven dongle doesn't even light up. I know the original dongle doesn't fit properly on the B8 due to the aperture in the trim being too small, got round this by removing the white cover from the dongle and it can definitely plug fully in then.
I have checked the Data bus diagnostic interface fuse (number 5 in the diagram below) and it has continuity. Anyone know what my next steps should be? Is there perhaps another fuse to check first or am I even checking the correct one? Thanks.
