Turbo - red circle of death, perhaps a fix for my car... but battery idle issue

[CHP]

28/11/2024: brand new turbo.

Hi byebye, sorry to hear about your problems.

Unfortunately red circle of death is more common than 1 member on the forum constantly want us to believe. It's simply wrong. I had two lemons and both taken back (last concluded yesterday) by dealer without any problems. @Petzi calculate minimum fault rate if you can. Simple probability calculation for one customer receiving two lemons.

I have no idea how leasing rights work but you may want to contact FirstEV directly. He had a similar experience.

Like you I didn't believe the software update would fix all problems. I explained the rational of my assumption in writing but agreed to follow dealer's proposal as they are the experts and were absolutely confident that software would fix the problem. I allowed them to keep the car as long as needed (I was provided with loaner) but made clear that I would return car without further discussion if fault would reoccur. The dealer agreed. The end is pretty obvious ;-).

The Macan is amazing to drive and my Porsche dealer has been brilliant. Porsche Germany support and communication for their electric cars however is suboptimal and certainly does not meet expectations. I am pretty sure Porsche is aware of this but mangers tend to like cutting costs for IT and customer services to increase their bonuses.

haha thats something. pretending that i am the minority.

I simply singled you out for always brushing off other forum members concerns. Numbers of those with problem are still stistcically small but there is no need to minoritize them.

On a second note, majority of those who did encounter more significant problems with Macan EV complain about poor handling of faults by Porsche.

I think there's a lot of misinformation about how our cars' batteries are managed. Porsche (and no other brand) provides details on how the battery is managed and the power consumption of its various components. It's truly outrageous that this information isn't provided to the rightful owners. That said, I'd like us to have access to reliable data on the causes of energy loss and to know what limits are considered normal and what aren't.

My car loses about 1% of its energy daily. I'm aware that a parked and locked vehicle consumes energy. The key is how much energy is "normal."

(The app isn't useful for checking this data because it doesn't update the information until the doors are unlocked. You have to open the car and check the System of Charge (SoC))

Facts:

There are known energy-consuming components:
- Alarm/immobilizer: permanently connected
- Wireless communications (5G): the car periodically connects to the Porsche central station
- Comfort access: constantly listens for the key being nearby
- BMS (Battery Management System): this could be the biggest energy consumer (I'm not sure)
- The battery's own chemistry consumes energy in the form of heat: my garage is currently at 12 degrees, but the battery is at 18 degrees
- Our car has dozens of ECUs (Engine Control Units), but I don't know how many are operational and consuming energy.

There are surely more energy consumers that I'm unaware of. The question is whether we can calculate this consumption.

A Raspberry Pi 5 can consume about 18W. Would it be reasonable for the car's electronics to be equivalent to about two Raspberry Pis? In that case, we would have 18W x 2 x 24h = 864W/day. If the SoH were 93kWh, that would represent almost 1% of daily consumption.

Is this calculation reasonable?

What do you think? Can anyone provide technical information about the energy-consuming components?
