Required vehicle update 37F1 to Transmission Control Module
RVU 37F1 is a required update to the S-tronic transmission control module (TCM, not ECM) to "optimize gear shift comfort". Per Momentum Audi it will have no effect on performance since it does not alter the ECM, it should just make the shifts smoother. It was issued on October 30, 2009 and applies to 2010 S4 vins 003862-075320 and S5 Cab vins 005233-013475. It expires on December 30, 2012 and the dealer is requried to install this patch on all vehicles in dealer inventory prior to being sold. By the way, I'm reading this straight off the technical service bulletin since I had it done to my S4 on Monday. I've been tied up at work with visitors from Japan & haven't had time to test it, but from what little driving I've done I've seen no negative impact. I hope that answers some of the questions that are starting to pop up on the net.

Please post your impressions about this update....
I don't see any problems with my S-tronic shifts right now and i don't know if I want some new update?
Like the bios on the computer - the latest is not always the best

I had this done about three weeks ago. There is noticeably less 'jerkiness' in the lower gears at low revs since the update. It is still there occasionally, but less than it was. No performance degradation noted.

S4 VIN 063618 here. Took delivery in very early November, and remember getting an email from my sales advisor telling me not to hurry back from out of town because his shop foreman had "grabbed the car for a required update." I can only assume this was it. Like Chris, I have attributed any residual rough shifting to adapting my driving style to the shift patterns of a new car (and vice versa, as I assume the transmission "learns" my patterns as well).
