- - Question on Turbocharger Wastegate Testing (http://forums.pelicanparts.com/mini-discussion-forum/945879-question-turbocharger-wastegate-testing.html)

I am experiencing similar problems to a previous thread MCS od JCW, code 2C57. I've replaced the diverter valve to no avail. The thread does not come to a conclusion. I've applied vacuum to my wastegate and it functions smoothly. Is my next move to check the wastegate? Is there anything aftermarket to cure this? 2012 N18 with 85K.

I have seen faulty turbocharger cause that fault if the diverter is OK.
