Trans has been good. Coolant leak has been stubborn. Accidentally put this in Sarah's Jetta thread a couple weeks ago, but it was Z4 info. The coolant loss and wet left side of the radiator has continued. Tempted to throw the radiator in it, but I really don't think it's a side seam tank leak issue. I think it's all the damn connections refusing to seal up right.
Of course when I did the below I was probably 4 more connections from pulling the radiator out.

All o-rings replaced on the driver side of the radiator. Couple hoses, trans cooler (which had a ton of RTV on it from a previous to me repair attempt) and the expansion tank I already replaced.
Hopefully good.
Only has distilled water in it for the moment, and I didn’t put the splash shield back under it. Hopefully done and can get some water out and antifreeze in after a could days not leaking.
Frighteningly little coolant drained out. Leak has been getting worse, like half gallon a day give or take, in a car size cooling system with single row radiator. Will be obvious if it’s fixed or not.
