My car's trip odometer has recently started to randomly reset to "0.0" while I'm driving the car. The odometer itself works fine and just keeps rolling up the miles. Anyone have any ideas of what might cause the spontaneous resets on the trip odometer?

That's a good call-out! I did install a new PCCM+, and the spontaneous reset issue did actually start following the install. I never thought about that being the cause. Choosing between a reliable trip odometer and the new PCCM+? No brainer, - PCCM+. I'll just live with the spontaneous resets.

If it helps to echo, I had a PCCM+ installed in Feb and the trip odometer started "spontaneously" resetting. As @spooltime mentioned - I will take the PCCM+ over the spontaneuos resets all day long, but if there's a patch or a fix, I would love to hear about it. I will be at the dealer and will mention this next week. Thanks for highlighting. I felt like I was "alone" and losing a small bit of my mind....

During that time, the tripometer did not reset (about 300 miles). Brought it back to the dealer to reseat PCCM. They did not see anything that could cause the reset issue.
a day later the reset returned.
considering this sequence of events, it doesn’t seem like a software update is needed. Doesn’t it seem more electrical ? Crossed wire or perhaps a wire that is affecting something controlling the tripometer ?

I started having the problem when PCCM+ was installed in my 996 cabrio. However, PCCM recently was loose in the dashboard , sliding out about an inch or so until I pushed it back in.
During that time, the tripometer did not reset (about 300 miles). Brought it back to the dealer to reseat PCCM. They did not see anything that could cause the reset issue.
a day later the reset returned.

Tell your service department to install the fix for you. Better yet, see if they will give you the file and share with us. It’s very easy to install.

This is tantamount to Apple making you bring your iPhone into the Apple store for an IOS upgrade and charging you.

Guys over in Europe originally discovered the issue and their dealer worked with the Porsche Center in the UK to implement the fix. The dealers refuse to give their customers the fix, unless they pay for the service which they are charging 2 hours for a 5 minute effort.

I have been searching and I haven’t found a download. I was hoping my friends in the UK would be successful getting the download, but they haven’t. There is a navigation fix posted on 911UK, but that is for a different problem. I will wait until next year, then get a new unit under warranty, if the fix is still unavailable.
