Mein Auto: 2005 545i Sport
Refreshing info as my dealer says the car's ('05 545) "fuel-saving" program tells it to up-shift when cruising at about 37 mph and I should shift it into sport mode to keep the car from surging. This tactic does indeed keep the car from surging at this speed but it consumes more fuel and the transmission shouldn't behave this way. Looks like from these threads there is a software fix and it's covered under warranty. I'm calling my dealer now. Still kicking myself from parting with my beloved '94 540.
