I am cross posting this question. My Cayenne (955) has been in my lift for two weeks whilst I did a valve cover gasket/intake refresh/ starter r&r. The battery has been disconnected. I hooked it back up today and went for a drove to check my work. The odometer has reset itself to 8 miles (14 now). I want it to read 180,200 like before I disconnected the battery. I have a durametric enthusiast kit but don't know the limitations of it or the pro version either. Can I set my odometer back to the correct mileage? I recall the 928 being able to be adjusted for the first couple hundred kilometers or something. Does this hold true with the 955? Dealer is 90 miles away.

Impossible for the odometer to reset isdelf like that. The miles are stored on a chip in the actual cluster, same as 89+ 928's. Me thinks you're leaving out parts of the story

I am leaving nothing out of the story. Here's a photo from a few weeks ago and a photo from today. If you believe I have a 14 mile 2005 Cayenne S I'll sell it to you for list price. I enjoyed having the mileage show 180,000+ and wanted to see how high I could get it. I need help fixing this. August 27th, 2017 before I drove to vail
odometer now, December 27th, 2017 after sitting with battery disconnected for two weeks
This is above my pay grade but if the discussion at the link I found is correct the Durametric won't touch the odometer. Sounds like you need a PIWIS 2.
Jeff, I'm not familiar with the Cayenne, but does it have two trip odometers, or showing a diagnostic code, or a message?
In other words, try pushing the trip odometer button a few times?

Yep, tried that. Just resets the trip odometer but doesn't change the total mileage odometer.

Quite a blanket statement that is wrong. It happens to 996, 928, 955. Thanks for sharing.
Now, to those that actually contributed, thank you. It looks like I'll be getting an obd2 odometer reset tool thanks to the suggestions from you guys.
The odometer chip which is housed in the cluster is tamper proof, it is highly unlikely it would just reset itself.
It appears you know everything about odometers. So, tell me what I did when I used a 13mm wrench to disconnect the negative post on the floor that goes to the battery and then closed the door to be opened two weeks later and reconnected.

You should really try hard to remember the exact sequence of events. I know that a lot of people over their lease mile allowances would pay good money for a You Tube video of this trick...

I disconnected the battery negative cable at the floor mount under driver's side floor mat. I wrapped it in a large towel. Two weeks later, when all the work was done, I took the ground out of the towel, placed it on the negative stud on the floor (probably sparked a few times as it came in contact with the stud) and tightened it with a 13mm wrench. I put the floor mat back and started the car. The odometer then said 8 and the trip odometer said 8.4.
I hooked up my durametric enthusiast edition yesterday. The mileage in the cluster says 40km (what it was after driving it a bit), the alternate mileage indicator also said 40km. I have no fault codes so there are no stored miles for any codes. I then hooked up a durametric pro edition and went into coding to see if there was a way to set the mileage. There was not.
I called two separate Porsche dealers. They both said the factory tech system they use cannot set the odometer. I tried pressing them to tell them this was basically a new cluster but they wouldnt hear of it.
I have two options now. Do nothing and just record the date and mileage change in my records or spend $250 on an internet sold device that will let me change the mileage via OBDII. I am probably going to just leave it.
Anyone want to buy a 2005 Cayenne S with 37 miles on it? To make me feel better, I just got my Blackstone oil report back. It says my engine is doing fine with less than average wear. So, my cold climate V8 seems to be holding up just fine.
I'm gonna guess that the dealer is being "less than truthful."
But if they are telling you they can't do it, it is another way of saying they won't.
The PO of mine had the display in the cluster go out, and found a used remanufactured one. The dealer here reset the odo to the correct mileage when installing it.
Given the fraud potential of resetting the odo, I'd be a bit skeptical of an 'internet sold device' that claims can do it.
And, FWIW, I "reset" the odo in my 928 to zero as of my purchase. Odo gear was bad when I bought it, and PO's records showed the same mileage for about 18 months prior to my buying it. Add in the fact that it's a grey market Euro, and there's no way to ascertain the actual miles on it (cluster was changed when it was federalized). I have the old reading (about 61k) both in my record book and written on the back of the cluster.
Kind of a shame. It would be cool to see one with 200k+ showing on the dash.
Edit to add: After a couple PMs with Jeff, I dug out the records. The cluster that was put in was a remanufactured, not a used one. It may have been 'rebuilt' with the ability for the dealer to set the miles to match the car it was installed in. I don't know. Correcting this for archival purposes.

I had a quick dig through the manuals I have.. I don't have Cayenne ones, but 996 and 997 manuals both refer to recoding the cluster using Porsche tools, so guessing its the same procedure for 05 Cayenne.
Relevant parts of their manuals here - looks like the PIWIS Tester II is what you need.. but they're $13k.. so making nice to a friendly workshop is the way to go.
