Can anyone explain to me what this does and how they are going to fix it. It sounds like a major fix (thank god I am still under warranty ). This make me want to about my young XB. I haven't even hit a year yet.

 

Once you get involved with silicone, you pretty much do what the diagnostic tester tells you. At least you have a hard failure and not some intermitent problem that they have to chase. If you had a code reader you could decypher the codes but that's what warranties are for. Sh*t happens.
