I am having an array of issues with my 2006 Audi A3 Quattro.
Random misfire on all cylinders.
O2 Sensors randomly not functioning correctly
Random Engine Sensor issues
Headlights flickering
ECM reporting Low Voltage (12.3)
and a few other things I can't remember
I was convinced it had to be a ground issue, so into the ground straps I dove.
After I cleaned and tightened all of the straps, added a couple extras for good measure, the problem persisted. I went in with the powerprobe next, Around all of the above issues I noticed that I had a beeping on the 12+ side, it does it all the way in the fuse box, only when the engine is running.
Any Ideas?
