Default half yellow engine light without error codes - 7th June 2015, 07:34 PM

When i step on the throttle, around 4000rpm, i get overboost which is fine. After that though, when i lift my foot from the pedal as the car slows down, i get a half engine yellow light. The car i believe gets in limp mode and i cannot get overboost, generally it seems as if the car has lost its power.
If i pull over, shut down the engine and start up again, the yellow engine light disappears and driving power is back again, but only just for once because if i push it, the same story happens (yellow half engine, lack of power, no overboost etc.) until i shut down engine again etc.
There is no error code diagnosed when using Torque from my smartphone, isnt this strange?

Check all the turbo pipes to look for a lose connection.
