Dear Pawel, I red the e-log, but it is actually not clear what the 1-D2 problem is. Assuming as you say it is a cabling problem it must have been present in eons i.e. even the dAu- run. Certainly I am not aware of changes beeing made since. Could you make both the problem as well as the remedy more clear. For the un-informed reader the e-log is not detailled enough ?
