Digital clock in main dash
Mike_H replied to WTL's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)
I picked up my 2008 Cayenne S (Nav & Bose, PCM 2.1) from the dealer a couple of weeks ago after having the battery changed. Right after I picked it up, sometimes when it starts, the clocks on the dash & “below PCM indicate either the correct or wrong time. When they indicate the wrong time, after driving for 30 seconds to 4 minutes the dash & “below PCM” clocks change to the correct time? Took the Cayenne back to the dealer to have them look at it. After several days and lots of diagnostic tests, the dealer reports that no system is reporting a problem. All they did was set the correct time zone since it wasn't correctly set when they changed the battery. So they reached out to Porsche NA for help. Porsche NA reported that they have recently started to see the issue with older systems. Something to do with an update of the world wide GPS system? Nothing they can do about it. Now, it has been two weeks since battery replacement/corrected time zone and the clock seems to be working. After reading a thread on another forum, I looked for the date and it no longer appears in the display! I found the date digging down into the sub menus and it is also wrong…it’s 2/23/00? Seems like the battery replacement also effected the clock but that was not fixed with the correction of the time zone. Is your clock at the correct date and properly indicating on the PCM2.1 display? Thanks for your help.
