Code P0029900
Anyone else ever had this code? Turbo underboost
My car sometimes doesnt run perfect when you drive in the city for a while at low speed! when you throttle than it stutters a little! (Like the turbo’s has to wake up)
so bought the Carly app and gives me this error code!
CEL wont light up ?
Anyone now what this can be?

Pop the hood and have someone give the car small revs to spoil up the turbos, listen for a whistle if you don’t see any issues with the hoses
