A5 TFSi - jerky gear changes

[Audible]

I am seeking advice.  If this topic has been discussed, please direct me to the appropriate thread.

I bought my A5 nearly 2 years ago.  It was in excellent condition except for one thing, which I have tolerated.  Occasionally, and I cannot find any pattern to the occasions, it will jolt violently as I stop.  This does not happen every time, so I know it is not my driving technique, which I guess is what you might think.  I have tried to see if it occurs when on the flat, upslope, down slope, stop-start conditions or after a long run.  I can find no pattern.  I appears to be random.

Anyway, I have tolerated that until now.  Now, I am finding that gear changes, when in either normal Automatic or Sports mode are becoming jerky.  More worryingly, there can be a tiny delay in accelerating away from a standstill - no fun when you are entering a busy roundabout.  

Has anyone experienced this and can they give me a clue as to what the issue is?  I have an inherent distrust of garages who like to try all sorts of experiments at my expense before finally finding the solution.

Thanks in advance for your advice.

When was the last service of the gearbox? Oil change ?

Years ago.  Too long. Tens of thousands of miles.

I would start with this. Multitronic gearbox needs to be services every 38k miles

Thanks Niedzial.  Apols for the late response.  I have been living with the fault for a while to see if I could find a pattern.  No luck so far.   Your advice is much appreciated.
I'm taking the car to a gearbox specialist tomorrow.  There are various options suggested:

1. Transmission fluid
2. Software update
3. New & expensive Mechatronic system.

Wish me luck!

hey Carol, good luck with that & thanks; your enquiry has got me off my backside to do something about my own similarly misbehaving gearbox which I also have ingnored for too long.

happy motoring
