Strange Electrical Issues

Last November my 06 Jetta flipped out - was hard to start (long cranking) and when it did start, the oil light was flashing with audible alarm, traction control light was on and tachometer went to zero (but the engine was running). I stopped the engine and restarted but the same thing. Given the symptoms, I suspected an electrical issue. I took it to a nearby O'Reilly and after testing it, they said the voltage regulator in the alternator was out.

I bought a new alternator and that seemed to fix the issue.

Fast-forward to today, when the very same thing happened. Same symptoms and the car would die when stopping unless I kept the RPMs up and held the brake.

Then the problems mysteriously went away. I just got done driving it to O'Reilly and they said the battery and alternator test fine. Battery is 3 weeks old.

Has anyone ever seen *intermittent* voltage regulator problems or does this sound more like a loose wire somewhere? The fact that a couple of systems are showing low voltage makes me suspect a common source (battery/alternator) rather than a locally loose/shorted wire. Ground straps are good and recently (month ago) polished and securely attached.

VCDS scan below. The radio is disconnected and the cruise switch is known faulty. So disregard those.

Thanks!

Always check grounds when "wierd" electrical issues happen in any VAG product.
Also, do you have the correct battery? 3-week old battery? Has it been LOAD tested?

The ground straps under/near the battery tray were polished up a few weeks ago. Are there others somewhere else?

The symptoms you described in the first part of your post are consistent with ECU to engine harness chafe. It is a common problem in the A5. http://forums.tdiclub.com/showthread.php?t=239987 Run a search for other threads.



The other symptoms you mention are consistent with corroded grounds or fusible link connections on the engine space E box forward face.

Good luck with it.
