P1249 Wastegate control valve performance

With this code there will be a noticable loss of power, this is due to the waste gate not responding  It is important that you go to other code that are present with this code that  can cause this condition , if this is the only code, the turbo charger has to be closely inspected, What can set this code can be from the EGR to a air leakage getting past the MAF (mass airflow). and this includes the air charge cooler. If those are are correct it is to your advantage you take care of the ECM Recall first. There is Campaign 13B16 which is for the ECM update, Campaign 12B34 this is a update for the turbo Nox module. and 12B33 Nox sensor module update. and Campaign 10B 17S1 which is for ECM / TCM power increase calibration. .Some of these Recall can be contributing to P1249.especially if the MAP sensor is being affected
