I would advise doing a reset if the fluid has not been changed. You should be changing your fluid every 30k - 50k depending on what works for you ($$$). You might have other issues that plagues your model. I don't know if being on the 5 series site will help you out much. It might get you in the general ball park but actually fixing your issues might be correctly detailed on other sites that cover the model you have.

I read an old post of yours pointing somebody to the KyleB thread, which I think I found on Google but seems to have evaporated...also, any advice/instructions you can provide on using INPA or some other software to update the trans computer would be great.
