Heater Recall Leading to Battery Issues?

[snstevens]

how long did it take to complete the recall? I've never gotten my vehicle back from Porsche within 1-2 days.

Mine was done in one day.

My range has also improved a bit since that service, but I think it’s all to do with the weather getting warmer.

Thanks! I saw one note here about it taking 5 days

mine was also done in a day... they probably have got a knack for it now.
I think, these range "improvements" are largely due to some software upgrade that wipes/recalculates the range...

2.5 days for me.

My car was is also waiting for the parts for this recall. It was in to repair small defects that were done the previous time it was there, but it has stayed waiting for parts for this recall.

Took 5 days, but then again I had them look at why my windows were rattling when music was being played. So should take 3-4 days

3) I don’t know exactly what it means, but when my heater stopped working, the 12v battery would be showing 14v. When they fixed the heater (and when the old one was functioning) the dash always shows 13.5v for me.

I noticed the same thing after my heater failed and I was waiting some days before taking it to dealer for replacement.
My conclusion is that 'higher than normal' dash readings for battery voltage is a trouble sign.

I just had the heater replaced, and the reprogramming of the Central Computer vis PIWIS.
Does anyone know what is included in this software update?
It took one day to do the work ( including two new front tires) and everything seems fine.

By the way, the code was WPN9
