Can say about the NOISE without listening to the car however the
performance is
a common "fault" of the gearbox ECU remembering how you drive or if a
secondhand
car how the previous owners drove it.
Read this carefully:
Get in the car and close the door
insert key/fob into socket (DO NOT START ENGINE)
DO NOT PUT FOOT ON THE BRAKE PEDAL
Press the engine start button - all idiot lights should come on but engine
will
not start.
Press foot hard down to the floor on the accelerator pedal and leave it on
the
floor for 25 seconds (THAT IS 25 SECONDS)
After 25 seconds release the accelerator and press the engine stop/start
button
let the car sit there for a FULL 2 minutes - this is imperative.
Without removing the key/fob - now start the car and go for a test drive.
You
should feel more response from the throttle. Car should now start off in
first
instead of 2nd. Acceleration should be snappier.
Do this occasionally like every 3 months - some people that know of this
do it
at every fill up but that's taking it a bit too far.
I must add that you will also notice a slight increase in fuel consumption
or
decrease in mpg as you will be using the lower gears more and playing with
the
throttle more - have fun.
Where about's are you in the UK? (not your address but general location)
There are other tricks for the E65 range like how to reset the service
lights
and reboot the onboard computers.
What sat-nave DVD are you using?
