Except that the car displayed the problem described before the mechatronic replacement, and after.. and as you know the car was treated with care.
The only thing I can't vouch for is the gap in the mileage between when I traded the car and when thezoneR32 went for his drive (around 300-400km).
However the issue described sounded similar to the one that was driving me nuts as well. On the plus side the problem didn't appear to worsen and I never got any false neutrals or any other odd behaviour. I now completely understand the love/hate thing with the gearbox and the car itself that others have reported over the years.
