new X53 3.0L. got the P1074/1076 codes, the usual stuff from what I've seen on the board. I replace the lower boot, had a big crack in it. hoped that fixed things but no luck. X5 has 140k on it. not sure what has been done to it, only had it a month. runs/idles perfectly. just can't clear these codes. thinking about the CCV system, just replace it and get it over with. sooner or later, it needs it, right? tried spaying carb cleaner to find intake leak, nothing. pulled the DISA and it looks/feels tight with a nice oring still in good shape. got under it, checked the vac lines to the dip stick tube, all look good, not old and crumbly. So order the CCV and hose kit and just swap it out to get it done?
