I took your advice regarding the battery. I discounted it and cleaned the terminals and connectors. However, the battery information was never entered in the car system. The make of the battery was not one of the 2 listed brands; therefore, selected the choice “reserved”. I was able to enter the serial number and was accepted; but was not able to enter the battery model/type despite entering the correct numbers that is on the battery sticker. I tried every possible way and order of letters and numbers but none was accepted.

Can you help please.

Any thoughts?

Do you think if I enter the information for any other previously accepted battery, it would work. 

On the battery itself it shows on 600109090 as the battery type.

Costly, troublesome, and requires its own special workshops. I am seriously thinking of getting rid of this Panamera after I get it running again. I have had endless problems with this car.

I have had a 2004 Carrera 911 for 20 years and never had any problems at all. All I do is the oil change and regular periodic services.

I have a question:

- what do the different LETTERS at the end of the same Porsche part numbers, and why.

- Are electronic parts with identical numbers but different ending letters interchangeable.
