I am having a problem with my 2013 350 blue efficiency. The car drives faultless when it is just doing its thing but the problem occurs if I have to accelerate hard from a standstill. It will bog down and jump about till I lift my foot and accelerate slowly.
 
When it bogs down and starts jumping about is there a yellow flashing light on the dash ?

Turbo actuator is sticking, or the exhaust backupressure sensor is giving suprious values.

Both can be quite voilent. In the absense of diagnostics proccess, I would replace the backpressure sensor, as its easy and cheap.
 
Thanks for the info. Is it something I can see with the icarsoft diagnostics tool?
 
backpressure sensor reading can be viewed under actual values.
