Help please - OBD port dead!!

[mk2vr6]

Have tried no end of things but cannot get power to obd port. Pins 4 and 16 in my audi show 12.4 volts with ignition off, Sharan shows nothing

If i give pin 16 a permanent live vagcom still comes up as no response from controller.

Was getting k1 short to earth when testing in options but disconnecting the airbag controller got rid of this, and now got ok on k1 and k2 - status ready.

Can Ecu be knackered even though car still starts and runs?

Anyone any ideas?

I had a Golf Mk4 like this.. Nothing could talk to it at all, we then discovered there was no engine management light in the dash coming on when we started it.. it run fine too & no issues but just wouldn't interface with anything & no engine light..

Might be your cable perhaps?
