dont just disable it because you cant fix it. Keep at it and you'll get it. run all the tests possible .. keep at it, the same thing happened to me a few months back and i kept at it and now MUHAHHAAH its 100% no specialist could fix it i found out the problem myself and then fixed it myself....and then i went down and stuck it up the arses of those "mechanics/specialists" who told me there was nothing wrong.!!!!! MUAHHAHAH
