I drive a 2004 330Ci with the M-Sport package, featuring a six speed manual
transmission. I've observed something that I consider a little odd: when I
go to up shift (say, 2nd to 3rd), just as I go off the gas and begin to
press on the clutch, the car will jump forward briefly. It's like the car
had a sudden, short-lived burst of acceleration, though not caused by
stepping on the gas pedal.
I'm at a loss to explain how or why it happens. I've never noticed it in
any other manual transmission car I've driven over the years.
Any thoughts? Anybody else experience this?
