the esp light comes on whent is doing that

alx

what does it do? does the light only comes on or it tries to interfere with your braking?

have the car read. does it store any codes?

also, abs and esp may act up when the battery is on its way out.

do you run aftermarket wheels? tires? if speed/ rpm/ air intake ratio is not within factory specs esp will not be happy.

when turning esp light flashes and brakes are applied. no codes. battery is ok. i have swaped 4 tryres including rims from another vehicle still it does the same. above 30 kmph it starts to activate esp when turning either side

Correct size tires?

sandesh - you didn't say what year your 350 is or if it is still under warranty. If it is in warranty, the control module for the ESP probably needs to be replaced. Otherwise you may have to live with it.
