AUE (6683) might be a TI OPA727 in VSSOP-8 package.

Thank you for your suggestions, the BAV199 was also suggested to me from others, so I will order that. And the T4 yes I was also thinking some small signal diode like the 1n4148.

Yes I think so too, but still a bit suspicious because the TI datasheet says smd marking is only "AUE" no mentioning of "6682".

6682 will be a production/date code.
Datasheets normally show what it means.

There is some chance that the other marking is on the bottom side - if you end up pulling it to replace it, it's worth a check.
