How can i proof total mileage


Recommended Posts

Hi

Wondering if there is any possibility to proof the mileage of a cayenne, maybe through some software!?

Sevice books are cooked many times and recently very easy to get a 200.000 km car but you believe you bought a 100.000 km car. Any help is welcome. Thank you all.

You need to scan the DME with either a PIWIS or Durametric software system to find what you are looking for. You should also be aware that it is rather difficult to alter the odometer read out.

Thank you. You mean with a porsche durametric system possible to find out? A porsche specialist should know how to do it?Thank you

The Cayenne uses a different system then the Porsche cars and contain different information. Neither PIWIS nor Durametric can display the mileage information from the DME. Additionally altering the odometer on a Cayenne is quite trivial with the right tools. Abritus among others makes tools for changing the odometer in the Cayenne, these tools work well on the clusters that do not have a color screen. For the color screen cluster the adjustments are inaccurate but can still be done with a bit more effort. The only way that I know of to get odometer out of a Cayenne ECU is if the car has stored faults that occurred prior to the mileage adjustment. Then the freeze frame data of the stored fault would have the mileage from the time the fault code was stored.

Wow ! New direction of investigation this point.Sorry for my question but english is not my native language:FREEZE FRAME DATA....... Is somewhat like a memory of all codes which where shown during cayennes entire life?Is it tricky to find out this or porsche schould know how to do it?Thankx a lot

Freeze frame data is operating parameters that are stored in the ECU when a fault condition occurs. It records the current state of the ECU at the time of the fault to help the mechanic trouble shoot the problem. When freeze frame data is stored it usually contains some information like odometer or operating hours so the tech can determine how long ago the fault happened. So this data will only be useful to you if you have a fault condition stored.

But it should be able to show hours run time and average speed, from which you can calculate (within certain bounds) the milage.

I am sure the operating hours is in the system somewhere along with the odometer, but this information is not displayed in the PIWIS or Durametric. Someone told me recently that there is more information available if you run a vehicle analysis using the PIWIS 2 but I do not know if this has the odometer or operating hours. I will have to try it and see.
