'13 S6 factory ECU and TCU update

[Packy]

I took my 13 S6 in because the 1-2 shift was a neck snaper when cold at full throttle. it felt like mid shift someone would slam on the brakes.

The shop waited till next morning when it was cold but couldn't reproduce it. They went ahead and updated the TCU (had already been done at a year), ECU, and climate control.

What a difference. Much less drive by wire delay, faster shifts, quicker to get fully into gear from a start. In sport the shifts are quite fast. It also downshifts quicker and seems to have a smidge more power. Its the way the car should have been done from the start. I have always hated the slow starts from a light under normal throttle. No more, it goes. In sport its almost harsh for a luxury sedan, love it. For those who haven't had a tune done, you should request this.

Anybody know what the climate control reprogram was meant to accomplish? I've noticed no difference. Service writer is basically, its an update, what it does who knows.

On a side note, I scraped a wall pulling into the driveway. a very minor scratch hardly noticeable, most didn't even go through the clear bra. I had an estimate done and WAM, $3,600 for this little scratch. Cover has to come off then then the sensors have to be realigned ($1,800) damn! I'll live with it.

What was it you requested at the dealership? Shouldn't they so this upgrade for all S6 owners?

very hard 1-2 shifting when cold. lethargic shifting all else. throttle delay when starting from light.

I've heard Audi will not update unless you complain about a problem in which they have an update. Except in this case they threw in the climate control. I know there are some Audi techs here, can't recall who, sorry, maybe they can tell you what all updates are available. I'd like to know that also.

Good luck.

I hope you didn't get that estimate for paint work at the dealership, if you did it's no wonder it came back astronomically high.

paint and bodywork wasn't bad, it was the sensor and computer calibration. I wouldn't trust anybody but a dealer to do that.

Hey madyspop, have you tested 0-60 with all those mods? looks like yours is pretty well stocked. all I ever see is 1/4 mile times.

do you have the TSB numbers for the updates? They should be on the work order they gave you

I'll get the paperwork out when I'm at home and remember. I generally only pull up this site when its slow at work. :)

Sorry, I have the paperwork out and it only says performed SVM updates for ECM, TCM and comfort control. No numbers.
