Hi all, I just joined the group and am having some problems with my 2005 Porsche Cayenne. When I drive a few miles it stalls and I see a message saying Reduction on and reduction off. I your help please, and thank you in advance for your assistance.
Hello all I'm a first time Porsche owner and I'm new to this site. The site looks amazing - I have already picked up a lot from the posts -essential given that the Cayenne seems to be full of surprises and quirks! I recently purschased a 2004 Cayenne Turbo with Bose system. Is there any way of telling whether my car has the second battery installed or not, without taking the trunk apart?
