2009 335i Hesitation on acceleration

Hi all,
The response during acceleration has changed drastically, where there was once a linear power delivery now it is slow to react and feels restricted, its also hangs onto gears (its a DTC)

Diagnostic software has been used to identify any faults and nothing has flagged that would indicate any issues.

has anyone else had a similar fault?

thanks
Beanster

Don't know what diag software your using, but based on my experience, I would seek out a BMW Indy who has the latest BMW diagnostic software. I had a mystery hesitation that I couldn't cure. My Indy's software showed the low pressure fuel pump controller was shot. Replacing the controller cured it immediately. I'd never have spotted that myself...
