No more details and that is the only report, Indonesian leak, maybe a pinch of salt needed.
Also doesn't explain how a defective sensor was replaced and still the a/c is getting dud data on that side. Either there are a whole batch of defective sensors out there (so we should be seeing failure on NGs as well) or there were two problems co-occurring.
The sensor that was removed could have been defective in a way that doesn't produce a wrong AoA.
Actually the maintenance log indicates that before the AoA sensor replacement there was no "Airspeed disagree" or anything else that would indicate an "AoA disagree" but rather air data missing intermittently for the captain.
So to me it seems very likely that during that replacement the offset error/ AoA disagree was introduced.
But it's not at all clear if the new sensor was the problem or the act of replacing it introduced an cabling or other error down th eline.
