Well....something has changed for the worse on the Audi. Fuse #13 (located in left plenum just below windshield) powers many components such as Secondary Air Pump, Evaporative Purge Valve, both Fuel Metering Valves, both MAF's, etc. Earlier in this thread Jack stated that this fuse and related components need to be evaluated. All of the scans so far show that the Secondary Air Pump, and Evaporative Purge Valve, are shorted to ground - when I unplug these items the scan then shows an open circuit. I did measure the resistance of the Evap-Valve since its easy to get o...and it is within specs. - so I assume the "short" must be after this component. What is odd is that even thought the scans show these are shorted to ground, the fuse #13 does not blow. Well....all of that came to an end as of this morning as this fuse is now blowing at each start up. So the problem has escalated...maybe this will actually help me find the issue now. I will work on the Audi again tonight. Also...I still plan to contact the independent Garage today to consult with them about this....if I can't find the issue I'll have the Audi trucked to them.
Easy ..........now unplug each shared track until a lower AMP fuse doesn't blow and there you have it by isolation.
Then change that component or overlay the damaged wire harness......
No one needed to do that considering what you already accomplished.
