Thanks for your comment. I'm sure (and I hope) I'll be able to play the trills better next time, as part of the whole partita.
About the Tureck version however, I must strongly disagree. This is just my opinion and I really mean no offense, but this is by far the worst professional, or any, version I have heard of this piece. The left hand at the beginning (and in general often the weaker voice throughout) is barely audible, sometimes vanishes completely, and has no direction, it is just notes played in succession (sometimes not even that with the missing/inaudible notes inbetween). And the way she plays the trills is very irritating to me. I feel that at least a short stop should be played on the 16th note after the trill, I circled them here:

otherwise the feeling for the note durations is lost, and Bach would have written it differently if he wanted it to be played the way she does.
Another thing that bugs me is the tempo. I find it too slow and it adds to the overall boringness of her rendition. Also at places it feels sloppy and uneven.
I also listened to the other movements of the partita and although this is not what this topic is about, I just have to say: except for the gigue, it is absolutely horrendous.
I never liked the way Tureck plays Bach, because I feel her style of playing somehow sucks all the life out of the music, and this is no different.
Sorry that I react so emotionally to this performance, but I mean, I made a midi version of the prelude in musescore which sounds better than hers, and I feel for someone who is famous for their Bach playing this is just not acceptable.
Just to be sure we're talking about the same version, this is the one I listened to:
