There are two types of preconditioning.
Cabin / Climate preconditioning - set from the app or PCM to either warm the car's cabin to your preset temperature. This has little or no impact on preconditioning the HV battery for DC charging.
HV battery preconditioning - can only be set when...
Switch what on or off?
PIRM:
NAV --> Settings --> Charging Planning
Then adjust your % for minimum charge at destination or charging stops as necessary.
Ok so the car was actually preconditioned then unless you were driving like you stole the car in Sports Plus to get to such a temp. Wasted energy in the end (not good for range!) if you don't intend to use it.
32C is the normal target to optimise charging speed at DC EVSEs. There may be a variance between J1.1 and J1.2 Taycans due to the battery type / chemistry.
Preconditioning is only for DC charging where the EVSE is 50kW or more.
Given you skipped the PIRM nominated charging location and not clear whether an AC or DC was the target I suspect the cooling wasn't optimised if indeed it was needed. When you got home and powered off the car logically the...
PAR not essential but desirable. Too expensive IMHO which explains why it's not common on UK cars.
RAS worth every penny.
HD Matrix lights are superior to standard Matrix.
Burmester I'd baulk at and Bose is good enough.
HUD I would skip as you already have excellent displays and this just...
I never had an issue with a profile and a recurring timer - it just worked and was always 100% reliable.
When I switched to OVO Charge Anytime I then ditched the location based profile and associated timer for my main home and relied exclusively on the OVO app for controlling charging...
Porsche EVSEs don't have programmatic capability and so My Porsche app / PCM controls the charging session unless using your energy provider's app (common kn UK) which in some cases can talk to the PCM directly.
Agreed but in my case I always had to use a profile (location based as I had two private charging locations) and a recurring timer set otherwise I did not have total control of the charging session. This was then superseded by using my energy providers app which could talk directly to the PCM.
It will have been sent to the car - how else would the car have charged (!) based on the parameters you set (% and time)?
Which generation of Taycan do you have? J1.1 has both a Profile and Departure Timer which was then changed with the J1.2 which has a Departure Timer with advanced settings...
Slow charge speeds from what I assume was a 350kW EVSE.
No info provided on battery SoC prior to each charging session.
Gen 1.1 Taycan with older battery tech and battery chemistry with a shortened peak charging profile.
Results are what I'd reasonably expect so no surprise.
It costs more to service a base Macan (UK) ICE than either a Taycan or Macan EV by as much as 50% on the same 2 year schedule.. I paid £750 for my Taycan's first scheduled service and £1200 for my wife's Macan T. Pretty sure if I had chosen the Audi equivalent vehicles it would have been...
...and reluctant to read the Owner's manual - https://manual.porsche.com/#/wpi/Y1A-2025-20241125-3B-RDW-1.0.4/en_GB/topic/id/59e8eb5920cbdeac8d24c0b364e5d713
I've been following prices in UK and don't see any evidence of this. Porsche EVs are premium / expensive and generally operate in their own 'bubble'. Taycan forecourt prices for 2nd hand don't appear to be rising but until you show interest / make a deal the truth will never be known.
Other...
As per the details I posted for Weissach UK 'YES' is the answer (PCCS update mentioned in the pricing) - check the website, contact them and seek assurance. Not all Indies are equal but worth exploring for routine items such as servicing. Software updates may be limited - I'm not sure.
