Dear Maverickz,
I also have Belta 2010 1.0. What I experience is shared below.
1- When I start car and its in 1st gear and when it goes from 1st to 2nd gear , engine really roars. But afterwards engine sound is normal. That sound is normal ? {FARAZ} Roaring sound is there.. I've read its in all CVT based Auto cars so I didn't worry too much. Even when I try to get quick pick-up / acceleration it would roar for a while.
2- When Car is in D mode and I lift my foot from gas , car stops. Earlier I had Vitz and in Vitz when it was in D mode and even if I lift my foot from gas , car used to still accelerate with speed of 5 km.
{FARAZ}Mine would move ahead at 5-10 KM/h
3- When I stop car on signal or need to park it and move it to P mode , RPM meter shows value of 1 RPM , Shouldn't it goes to 0 ?
{FARAZ}It doesn't go to 0 RPM since engine is still running, how can it run at 0 revolutions.
{FARAZ}By the way, mine stays at around 1.5 so this might also be the reason your car doesn't move forward when you lift your feet off the breaks... just a thought, could be wrong.
