Advice on new (to me) 25-plate Scala SE 116 TSI

Hi,

Note: my previous car was a 59-plate Hyundai i30, so all of this is very new to me.

Had my Scala for nearly two weeks now. Happy with it, but have noticed a few gremlins/niggles that I'm not sure about. I have done mostly short urban trips, but recently did an 80 mile motorway drive.

Things I have questions about:

1. The Stop/Start system keeps restarting at random before I depress the clutch or touch anything. Research suggests this is probably because of a low state of charge in the battery, and it does seem better after the motorway drive. Since I'll be doing mostly local trips with the occasional longer journey, is it better to disable this and/or is this something that needs investigating further?

2. The brakes feel as if the ABS is always working; there is a mild pulsing feel from the pedal even with only moderate braking. Is this normal?

3. On the motorway the cruise control worked OK, but on two occasions it behaved oddly; with an indicated steady 60mph the engine seemed to be surging then braking about every second, the effect was pronounced enough that my wife could feel it from the passenger seat. As far as I know the car doesn't have ACC and on the first occasion there was no nearby traffic anyway.

4. Again on the motorway journey, for about 1/2 mile, the tacho display was flashing the gear indicator "6" off and on as though it thought I was dipping the clutch. On two occasions it suggested changing from 6th to 1st, showing "6 > 1" !

5. I haven't used the radio much, but when I have, on at least 50% of the occasions it has randomly changed station itself.

6. The speed warning system only seems to activate when 3+mph over the limit even though it is set to "Standard".

Are any of these known issues, should I be concerned about any of them, and do any require taking the car back to the dealer?

Thanks.
