So, I have some imperfect behavio(u)r on my 150k-mile A8L. Sort of flares/slips a tiny bit, mainly when cold. I do have some codes, below, (brake light switch; and ABS, which I think is related to the BLS) which I will clear to see if they recur, and replace the BLS, but what is everyones' experience with changing the ATF? Is there a way to determine the current SW version in the trans, short of the $tealer $ervice dep't? Can I tell which (blue or yellow) fluid is in there or could it be brown enough to obscure its original colo(u)r? TIA for any empirical evidence!

Here are the most likely codes; I'll posted the whole scan in test forum
