hi
i have a smart 450 for2. after resetting by my MB star diagnostic. it would run well for only a few kilometer then sluggish (slow to shift gear) again. if i plug in again on star diagnostic it would say boost pressure too high. i would clear it again then try it. the same cycle came back.after few kilometer again slows down.i tried to unplug by battery and reset.again it would run well only few kilometer then slow again in shifting. the star diagnostic says to check turbo.waste gate and the hoses which i already did clean the turbo and check the line,even the waste gate is moving. i think this is electrical or some electronic parts as sensor or solenoid but i dont know which. can anubody help?

Use a gauge and check if Boost pressure match whith values in Das.
