I have a 2023 Audi A4 45 TFSI sedan, purchased in Germany. I reported this situation to Audi AG and they replied after some time that is "normal", "state of the art technology", ... According to the car dealer, this was successfully reproduced by himself on another car with same engine. How to reproduce:
- Drive off to a clear road or put the car in a dyno;
- On the gear box lever, switch from D/S to manual mode;
- Select 3rd, 4th, 5th or 6th (on 2nd is hard to reproduce), depending on the speed which can be reached and the road/dyno conditions;
- While the engine is revving around 1500 rpm, press the throttle above 50% and perform an up shift operation (lever or right paddle) when the engine is making some torque;
- No gear is changed until around 3200 rpm mark is reached and the up shift (lever or right paddle) is pressed only at that point.
The down shifting operation doesn't suffer from this issue.
But I found an ugly workaround: Remove the foot from the gas pedal, press up shift and then accelerate again. The engine then makes a small up-revving sound as if it accelerated when the clutch was on the way to get fully coupled.
I drove another cars, including one which has a similar gear box but FWD only (DQ381-7F), which none of them prevented me from up shifting when I think it was correct to do so.
Is there any software change which allows me to up shift when I think it's correct? Also, is there any technical reason which justifies this behavior?
