benny.boy2020 New Member 6 Member For: 12y 4m 27d Posted 19/12/13 10:05 AM Share Posted 19/12/13 10:05 AM Hi guys,My car is underboosting and getting an error P1228 wastegate open (under pressure).It doesn't run rough or anything. It is tuned at 18psi but only now making around 13-14psi.The car drives normal, wouldnt even be able to tell anything was wrong apart from less boost at high rpm.It pulls normal until around 4000rpm.Any ideas?I'm not sure if it is an intercooler hose split, as I was going through the papers when I bought my car and it did have the intercooler hose replaced under warranty with "wastegate error" done before. But cant be 100% as they didn't put the error code on the paperwork.Or not sure if it is the wastegate actuator.I cant take my car to my tuner until the 6th January as he is closed, any ideas so I can fix myself until I can take it to my tuner?Thank you.

I have been told previous that the B series had a poor position for the boost sensor which lead to a heap of issues Link to comment Share on other sites More sharing options...
