Talked to the tech today. He said the Chrysler Tech Line suggested two different brake related parts be replaced. So they are trying that. They "hope" this will fix it. But in reality he said the same thing again. It is showing Mercedes codes and they are not sure what they mean. This is the 3rd trip in for this. It is getting old!!!! The parts were to be in today and supposedly I will pick it up on Monday. Let's hope the saga ends here. I will be keeping mine fingers crossed.
