I have a 2009 957 3.6l v6 Cayenne. The battery was dead a few days ago so I replaced it. It now starts up just as it should but when run a diagnostic it says the alternator voltage is high reading 14.72. I’m assuming I need to replace the alternator to remedy this. I can’t find any information about replacing the alternator. Has anyone attempted this? It looks like it might be straightforward but my concern is whether or not the intake manifold has to be removed in order to get clear access. If anyone has any insight on this I would greatly appreciate it.
Having issues rebuilding alternator and with the coolant clips as well... Help videos guides would be appreciated...
A voltage problem that has been plaguing my 2002 996 C2 , 911, for ages, is when I first start the car, according to a cigarette lighter type electrical gauge device, everything is ok showing 'about' 13.3 to 13.8 volts, and a green light on the gauge. It remains that way ( 13.3 to 13.8 volts) for about 5 miles or about 10 minute or so, being driven or just idling. Then after that (a few miles or 10 mins) it starts dropping to as low as 12.8 to 12.2 volts,and in the red ? This always happens after the motor etc heats up,hence it appears to be a heat issue I think ? Last year I removed the alternator took it to a local alternator specialist that replaced the voltage regulator with an updated version ? And when bench tested it appeared fine. However once back on the car, it happened all over again ? Brand new battery, all connections appear ok, it's only AFTER the car gets up to a normal operating temperature, after about 10 mins or so. It baffles the hell out of me, and I always carry my jump start box , just in case. Any ideas as to what it is ? I was thinking of just buying another alternator and taking a chance on thats what it is ? Speaking of that, Pep Boys, Auto zone , O'Reilly's etc, sell them for about $155.00 with a lifetime guarantee ! The dealer wants an outrageous price, silly money, and a foreign car part place wants about $375.00 for a re-built Bosch. Any thoughts on the cheaper ones , and what my problem/issue could be ? This is a great car save for this alternator, electrical issue ??? Thanks a lot Dave.
