Battery State of Charge (SOC)

[Mountainman]

What happens if you release the button when "Time" is displayed? Are there any options after "Battery"?

You can then adjust the time if necessary. Hour number then minute number flash and you press the odo button to adjust. it's an even quicker way of doing it than using the touch screen.

70% on my 90TSI DSG, start/stop has been active from day 1 - now travelled 4500kms.

60% on my batteries SOC, 900km's now travelled. I wonder if this is due to me not having done many long trips?
For the most part start stop is active, unless in built up traffic that is slowly rolling along

80% new delivery reading.
Noticed the battery condition/test card with the logbook - wonder how they test.

They would put a voltmeter on the battery at idle and under load, and check the voltage.

I use an Auto-polar FIS+ in my Mk6 GTI, and it reports (amongst many other things) the CANBUS-measured battery voltage in my MFD in real time - handy!

I wouldn't be surprised if the Mk7 percentage readout is based on a combination of this measured voltage and some other age-related metrics, but I'm only speculating.

AdamD: I'd never heard of an "Auto-polar FIS+". I just had a quick squiz on the net. What an intriguing little device? What do you use it for and is it model specific for the Golf seriess? Does it work on a mkVII? Also, how is it different to the measuring parameters that are available with a VCDS cable? Is one better than the other? If so, in what areas? So many questions - sorry

Had one on my Mk6 — it was an interesting device, as you say.
It can do some of the things the VCDS cable does, but not all (and, of course, vice-versa) — if forced to choose, Rosstech would win.

As yet it doesn't work with Mk7, which has had its electronics completely reworked and seemingly made as difficult as possible — I wish it did, for mine is now languishing on the shelf.

With the MK6 the Autopolar reads the current charge rate as you're driving which is really only an indicator that your alternator is charging the battery. To do a proper battery test you need so calibrated equipment and a load testing machine to put a load through the battery. The battery needs to be fully charged to perform the test as you get incorrect readings if the battery is below full charge.

Start/stop sounds like a great feature for economy but I believe that due to the chemistry and how a starting battery works, the constant starting will reduce the lifetime of the battery.

Idle: OK. So, from your saying, am I right in thinking of the Auto Polar as as a real-time measuring platform but it uses the MDF as the read-out screen. A bit like having a VCDS sitting beside you monitring "measurement parameters" while you drive. Is this correct?
I assume that it plugs into the ODBII plug (same as the VCDS)
Sounds neat! Pity that it doesn't support the 5G/5Q platform
