Ok I get DSC on these conditions :
1) when the road is bumpy and you drive around 30-70km/h , DSC kicks on landings
2) when you driving around 65km/h for example on 4th and if the car shifts to 5th , and you will cruise on that speed than try to pedal it and DSC kicks in
3) if you are driving about 80km/h on straigh road and doesn't matter if you push the pedal 5% or 90% , it won't accelerate , just flashing DSC
The interesting thing is that on 0km-60km/h launchesh it doesn't flash , aswell as just driving in city (only sometimes).
By my experience it only flashesh when you are in higher gear and low RPM and trying to accelerate.
Conditions : 5Celcium , foggy day , 225/45 fronts 255/40 rear on 18 , as factory setup Pirelli Sottozerro II (full winter tyres)
Car is 320XD Automatic
I believe we all have pretty serious problem here.
