Using a vag-com 908 cable on my '99.5 2.8Q, I can't access the ABS module even though I have no trouble accessing other modules. Does this mean my module is dead or could it be a wiring issue? I've read that a dead module could still connect to vagcom, but could it be completely dead and unable to connect at all? If it helps, the ABS light turned on one day and hasn't turned off yet.
