Battery/Generator Warning

Recommended Posts

Thanks a ton for the responses on the idle dip. I will address the issue this weekend.

One other thing my '05 CS does...... Upon startup after a short drive (about 5-10 mins) in the morning, I get the Battery/Generator warning with three chimes.

This only happens in cooler weather and immediately following a cold start..... Not at any other time. I suspect the battery may be indicating a slow failure but i wanted to seek some guidance first.

BTW, no error codes stored per my Durametric scan.

Dunno if the Cayenne is different from every other vehicle I've owned, I assume not. The warning light is telling you the battery isn't being charged. Why? Could be bad connections somewhere, could be the alternator is failing. Take a look at what your voltmeter says when this happens (nice that they include it!).. you want it to be near 14V when the system is charging.
