Tiptronic Gearbox Issue

[Lyons]

Folks, when in 5th at around 35-45 if I accelerate slightly but not hard enough to drop down a gear, there is a sound like the car is labouring. If I put the foot down a little further it drops down to 4th and all is well.

I have a warranty on my car and it was in with Audi a few months ago and they said there was nothing wrong with it, and the service advisor just said to blip the throttle when I wanted to change. Initially they told me if I do this it will learn my driving style, but then changed their mind and said the tiptronic box doesn't have the ability to learn.

My point is that I shouldn't have to do this surely? I don't have to do it in any other gear, its only in 5th. In all other gears the box changes automatically as it should when needed.

Can anyone offer any advice or thoughts on the matter?

Car is an 08 A8 3.0TDi.

I would definitely take it to you're local audi/vw specialist just for piece of mind they will know more about it and may tell you over the phone for nothing, the guys around my way are awesome. That sounds like one of those problems that you notice as you drive it every day but Audi think your mental

If I recall there is a way to reset the tcu, I Think you press the accelerator to kickdown then turn the key to ignition only for about 20 seconds whilst holding kickdown.
