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.
