Car 10 months old, last week received a text through tracker to say there was a possible intruder and car may have been stolen. Its locked safely underground. Went to car to find I couldn't unlock it. Called the AA who suggested the battery was flat even though I did 200 miles the week before. The garage called to say new software needed to be added so is having that done now. The garage cannot find a fault with the battery.

Anyone had this problem? Could it be linked to the My Porsche App or the tracker?

Many thanks.


 
Yeah exactly the same issue - had a software upgrade now have an ongoing problem with the tracker not working - very frustrating
 
I had the flat battery issue on the last 992 I had. It would go flat after 4 - 5 days or eveb less. They traced it to the instrument binacle and it needed to be replaced.

I have read that if modern batteries go completely flat they are irrepairably damaged. To quote:

Why Is Discharging a Car Battery Too Far So Bad?
Even though 80 percent of the capacity remains when a car battery dips to around 10.5 volts, the battery is considered to be fully discharged because taking the cycle any deeper will cause irreversible damage to the plates through excessive sulfation.While normal sulfation is reversible, excessively draining a battery, or leaving it in a state of discharge, will allow the soft lead sulfate to crystallize. At that point, charging the battery will still cause some of the sulfation to reverse, but any crystallized lead sulfate will remain on the plates. This sulfate cannot, under normal circumstances, return to a solution in the electrolyte, which permanently reduces the available output of the battery.
The other detrimental effect of allowing crystallized lead sulfate to form is that it effectively shortens the lifespan of the battery in an empirically measurable way. If too much of this crystallization is allowed to occur, the battery will no longer be able to provide enough amperage to start the engine, and it will have to be replaced. https://www.lifewire.com/car-batteries-are-made-to-die-534765
