Does anyone here understand how the adaptive transmission on our BMWs work? I understand that the EGS will learn one's driving style and 'adapt' accordingly.
May I know what does the transmission adapt to. Does it adapt to the driver by:
1. adapting to shift points (i.e. shift at higher rpm if driver is heavy footed)?
2. staying in 2nd gear when moving off for a light footed driver?
To me it seems that these are the 2 most obvious way our transmission can adapt to our driving style... (am I having a too simplistic a thinking)?
I was driving my car (E46 N42) extensively to detect a rear axle knocking noise. This led me to drive in a weird manner... I was 'aggressively' stepping gas-let go-stepping gas to provoke a rear back lash knocking noise. The noise got more obvious after I tested more and more. Then it occured to me that the 'smart' adaptive EGS may be adapting to such a driving style and unneccessarily putting in more torque to the driveline as it 'believes' that's the way I drive - agressive depressing accelerator and letting go and agressive stepping again.
Having realised that the adaptive transmission is probably 'smarter' than me, I tried to drive as smooth as possible i.e. very gently stepping of gas and letting go and it seems that the frequency of the rear axle backlash noise is disappearing.. even when I do accelerate agressively on occasions.
My question: is the noise disappering because of my new drving style or the transmission has adapted to a smoother driving style.
How I wish that my car is not 'smarter' than me
Thanks for all feedback and advice!
