No alerts for me. These are my recorded tyre pressures over last seven days: My rear right (orange dots) always loses pressure ever so slightly faster than the other tyres. Has done since day one. Can see the spread in pressure is ~ 0.16 bar = 16 kPa = ~ 2.3 psi. So I find it a bit strange...

Yeah, not so fast. The on board SOH number you'll get from plugging in an OBD reader is a "black box" estimate of the battery's real state of health. Unless and until the workings of that "black box" are made transparent, I would treat the number it provides with a large grain of salt.

Because someone brought up the issue of "why would a car company tell lies?". I gave an example - to make their cars appear to perform better than they actually do. Car companies try to pull the wool all the time. SAIC will be no different. I'm not the one who brought up SoH. Mind you, SoH (if...

None. I leave it blank. It only cares if it's a Tesla car.

I know it's an old post but I was unaware this was an issue before buying our 2022 ZS earlier this month. My first charge stop on the drive home was the Tesla Supercharger at Raymond Terrace. Would have been mighty inconvenient had it not worked! But it was fine. 30.309 kWh and took 39...

I have such drives with economy rates that can vary by 20% depending on the variables in play. Here's the variability in my car's economy rate:

What did VW have to gain by telling porkies about emission testing? Trust has to be earned, and to do that requires full transparency on how the SOH value is determined and how it can be independently validated. If neither of those exists, then frankly it's at best worthless, at worst misleading.

How do you control for all the variables? Temperature, barometric pressure, wind, rain, road surface conditions, tyre type, condition and pressure & alignment, total mass, onboard systems use, speed, driving style, driver aid settings. regen level, etc etc.

The only way to reliably determine the SOH is for standardised testing of the drive battery. Anything else is just an algorithm inferring it.

Maybe ask VW. Note that we have no validated information about how the internally reported SoH value is generated. There are no standards.

Looking over a few months of data, the most my EVSE drew from the AC supply was 7.2x kW, with the car reporting a DC charge rate of 6.4 kW. Peak power draw recorded (by my Iotawatt at the circuit board) in last 12 months was 7.25 kW. My EVSE never reports operating at more than 31 A even when...

What an abomination.

Not everyone has that option, requires a software update. I have to go though the menus. ELK/LKA has been pretty terrible for me, we are on country road with poor edges and again the other day it once again demonstrated this awful habit of trying to steer me hard to the right and into an...

Mine is set to false. My ABRP is still updated with my car's actual SOC.

Yes, I have that set up, except I don't use ABRP much.
