Thank you very much for the explanation. Its ordered. I will report the test results when i get it. -
I will order it. Looks like a very useful tool. Thank you!

Its not the lighter socket which i used for charging device. I used on of the sockets which are in the car. Footwell, backside of the armrest, There are many of them. But as mentioned before, there must be some relation betwenn this electric gramlins and the sockets. Do i have to get them tested in some way or is the best advice: dont use it. Thank you to everybody for supporting me ! Donation is on the way:-)

Looking at the car today. No power drain. Starting not a problem at all .Driving normal. No battery warning signal. For me its like a miracle. I remember what members here always recommand. Look at things or changings which you did lately. The only thing i did: I used a external navi system and charged it via power outlet. The charging cable was still plugged in yesterday. I removed it. And today the problem dissapeared. Maybe this was the reason? I will see. By the way, with my cayenne s i had random PSM problems. In the end i found out, most of these problems appeared when i used a aftermarket charging cable for my iphone. I believe there is a relation between using power outlets and electric problems. I am dreaming or this could be possible?!

GREAT GREAT . Thank you ! I will do this. I keep you posted

+1, you can actually run a true load test on the alternator with the correct equipment such as a battery load tester. JFP .... I know i have to get it tested in a professional way. The only reason why i want to do some research by myself: I know when i bring the car to the shop i will get it back with some parts changed and a bill which will be much more than 1000 Euro. My cayenne s was there many many times in the last 2 years and in total i spent 10.000 euro for changing parts and labour. Many of these service jobs where not neccessary i found out.

Yes the battery was only 11.3 after some days the car was not moved at all. You are right, There is some drain for shure. The high reading of 13.96 was with ac, headlight. Radio, defroster on.
-
JFP thank you! You said must be between 13,5 and 14,5 But my reading 13,98 is in the range you mentioned
-
Sorry for my mistakes. I am writing on mobile phone. Multileter Reading with engine shut down 12,... Multimeter Reading with running engine 13,9......

Here is the multimeter reading

Here i am again. I try some things today because the car is still at home. First of all, i dont have a second battery in the trunk. After replacing the new battery last weekend the car stay all week without driving. I open the hood and tested voltage in engine bay plus / minus port. Reading was 11.30 I try to start the car. Starter turning but engine not starting. Using my s to make a jump start. Car is starting and running. I left it for some minutes running, drive a few kilometers and shut down the engine. Waited a few minutes and tested the voltage again. Reading 12.30 I started the again Reading 13.96 Does this test show me that the alternator is ok and working Proper? Or is it possible that a mistaken alternator also would show This reading? Thank you again

Hi. I am pretty shure i have just one under drivers seat. In the rear i can see only black round box which is the bose system . I will have a closer look this weekend.
-
Maybe if you change the headline "pronto" and ask a little bit more polite the people arround your area are willing to give you advise.
-
Last question please about this subject. The car allways is cranking slowly. Even today with a new high power batterie. Is this also alternator related or different subject? I read many times that these kind of behaviour could be related to alternator batterie cable issue. Could it be possible?
-
To be on the safe side i have to call the tow away service:-(
-
Second round . Now the multimeter shows ZERO. So for me it looks like the alternator is not working proper. Now my question. How far is it possible to drive with a fully loaded battery and a faulty alternator? Porsche Service is about 20 km away. Can i drive there?
-
I changed the batterie for a new one. Starting normal. But after some minutes of running car starts to rev a little bit higher at 1000 and some time later batterie sign in display appears. I connect the multimeter to + and - in the engine bay. This is showing 13.8 / 14.00
-
I would like to try first to take out the fuse for the dash allumination if there is one. According my om it should be number 40. somebody can confirm this
-
Hello to Belgium. The battery is totaly down and i thought might be better to replace. I have one at home. The display problem occured just AFTER i did thid jump start. So i believe thats not the original problem. Thank you
-
Here i am again. The car stay for some days and now nothing is working. Dead. I had to use my other cayenne to start the turbo via cable. Car started without problem. After i used the multimeter i bought to messure the voltage. Looks like the alternator us ok. The multimeter is showing same numbers on the turbo like in the s. So as i understand it cant be the alternator. Tomorrow u will change the batterie. I will see what will happen after. What i am wondering about it the following subject. The car is locked. Lights switch off. But the dash is fully iluminated. What the ...... Is this?

Ok. Thankx. I will let you know whats going on
-
I got it. Thank you!
-
Thanks again. Its a turbo s with 500 hp with just one battery under the driver seat. If i am testing the voltage according your information, what i have to learn from the numbers? If the voltmeter is showing the numbers you mentioned? Sorry for the stupid question.

JFP... According our conversation i was talking to BOSCH today. I thought cars electric system is their main business and they should know what to do. I explained the situation and the guy made me feel affraid. He told me " if you have a bad alternator regulator it could cause serious damage on the cars electric system because of high voltage spikes. Better dont drive anymore even some meters. Disconnect the battery too because it could be completely discharged and broken. Best way to tow the car to the next service station" He was very serious. Could he be right?
