Boost pressure regulator problem :(
Have some problem with the turbo boost pressure. I have changed the Boost pressure regulator and the problem is still there. A friend of me have an DAS and it tells the problem is Ground to short. Some problem with the red and green cabel is short to ground. The voltage between 1 and 2 should be 12 - 14 V but it is 0.75 V. Where does the red and green cabel end?? So I can make a test there. Any ideas?? (Mercedes w164 2007)
