S5 Tiptronic Shift Characteristics
I've had my S5 for a couple of months now and have a question about the shift characteristics.
This is kind of hard to explain, but I've noticed some "uneven" shifting when accelerating from a full stop. At a very conservative level of acceleration (throttle input around 10% maybe?) the transmission shifts very smoothly. I get the same when I accelerate aggressively. It shifts quickly and smoothly.
However, at a mid-throttle, medium acceleration (shift points in the 3K range?) there's an odd oscillation at the shift points. The transmission shifts and the RPM's drop for about a half second, but, then the RPM's jump up about 500 to 700 briefly before settling into the expected range. It's like I am "blipping" the throttle right after the shift.
I've got about 1400 miles on the car now and it seems to have smoothed out a bit, but I was wondering if that behavior is normal? Can those shift settings be tuned?
I don't have the sport diff or dynamic drive, by the way, so I don't have any way to change the setting myself.

I'm thinking about looking into software tuning options.

I recall reading somewhere that you can use VCDS to put the car into dynamic mode (save the diff or shock settings of course). Of course it's not dash selectable but even on cars without ADS the car has the ability to use the steering wheel and throttle/trans settings via the ECU. Might be worth a look.

I'm surprised I don't see much about these issues on this forum unless I'm just not using the correct search terms.
Taking mine to the service department to have it looked at soon.

Check with Audi. There is a software update that might address your issue. I had similar, but not exactly the same problem, and the update provided some improvement. However, you're likely to have to pay for this upgrade, its not part of normal service or covered by Audi's warranty.
