I have been driving a C220 Coupe Sequentronic for about 6 months
(20,000 miles), and am not at all impressed with the gearbox - a shame
as the rest of the car is great!
Sequentronic is mercedes semi-automatic, and it feels like a first
prototype. It is sequential, but also has an automatic mode. The car
has now been into the dealer for 2 services, during which they have
loaned me an A-Class. The gearboxes in the A Class (semi auto and
manual) are far better than the Sequentronic in my car!
In manual mode the changes are OK if you accelerate gently, and lift
off the accelerator before changing - although a friend said 'a bit
like a learner'.
However the auto mode is a joke - in traffic, when gradually
acelerating the change to second is terrible, and if you lift off,
then accelerate it often seems to get confused and takes a few seconds
to decide which gear to be in. The car has a cruise control function,
but in auto mode if this is set to a limit, sixth gear is not used.
Anyone else with a Sequentronic know if this is normal or a fault on
This is the first auto I have driven, but it seems like the auto mode
is set for a petrol rather than a diesel as it doesn't change until
pretty close to the red line, even with only half throttle - a waste
of time in a diesel.
The dealer said that the gearbox is 'not one of mercedes best' and
that they have has to replace a few, although when I complained they
made it clear that if a fault is not registered by the computer there
is nothing they can do.
What experiences do other Sequentronic owners have, and what has the
dealer done about it?
