I just had my 30k service on my 2015 Cayenne S eHybrid and they applied a software update. Now I am seeing 11 miles on my battery mileage display instead of the 14-16 that I normally saw after a full charge. I initially thought it was just the gauge, but noticed that my battery only mileage did drop to about 10-11 miles of driving (have run about 4 cycles so far). Same route as normal, so no other variables have changed.

Anyone else notice this after a recent update?

I have a note into the dealer asking for details. Wonder if they can roll it back or if this will correct itself after time.

 

I have had many hybrids, not a Porsche but tge idea is the same. I have an Audi so the tech is also the same. The range calculator is based on your electric consumption. If you drive a lot with your normal engine on, you will have a very low e consumption and high range. In the service they usually zero these and you will get a new range estimate. If you have been driving in emode more now, you will see a considerbly lower range. If you measure the total distance there shouldnt be a difference. This has been the case in my every hybrid. Also my Audi range has fallen 10km within 2 weeks, due to our temeratures dropping from 10c to 0c. Hope this helps. Range otgerwise shouldnt drop, unless they limited the available capacity of the battery, which I doubt.
