If you’re going to wait until Jan Joe, I suspect you might get even better deals if you don’t mind the spec much.
Mine is a factory order, so the spec is in stone at this stage, as is the price!
Tyre pressure recommendation is 44 PSI, 40 ish PSI likely to further improve compliance.
44 is crazy high, 40 PSI is even too high in my opinion! The car must drive like its on solid wheels at that pressure! I think 35-36-ish would be more like it. Most tyre fitters tend to default to mid-30's PSI in my experience.
VW bump it up to 40+ for emissions regulations, its nothing to do with optimising the car's setup. Volkswizard's latest video talks about this.
- IOS 26 Update has forced google maps navigation inside the left hand view dial and I can’t turn it off. Anyone had better luck?
This shouldn't be anything to do with an iOS update. You just need to configure what views/screens are visible on the main dashboard screen by using the VIEW and arrow buttons on the steering wheel. There's loads of various options.
- 12v battery in these new cars are nuts. Within 10 secs of getting in I get the 12v battery is depleted error message. So I have to turn on the engine and let it idle whilst I belt up, connect phone, turn off ADAS. Perhaps I need a battery charger.
Yep, these cars hate sitting at idle, or worse, sitting unlocked or with the ignition on (but not engine started). The 12V battery warning tends to pop up very quickly. Also, you may find that if this happens, the infotainment screen has a bit of a "moment" and can get stuck on "Loading settings" for several minutes on your next startup. All part of the MK8 Golf experience I'm afraid

What’s the weather like where you are in the winter Donster to run pilot sport 4S for winter?
Both Donster and I are in Ireland... the winter weather tends to be very wet. Generally very little snow or freezing conditions, they'd be a fairly rare exception. Michelin PS4S's would be a very popular all-year-round choice here on performance cars. I believe Pirelli's PZ6 and Continental's SC7's are considered as good, or even better perhaps.
