Could you shed some light on this one?
Thx
Any news/update on the 03 C-class dyno mode yet?
Another question on the dipstick for us?
Would either the 03 ML, E-class or CLK-class V6 dipstick work for us? What would be the limitations if they did?
Thanx for your time.

Drove a C230 coupe recently and found the autotran downshifted
itself during braking more agressively. As a result, less brake
pedal effort is required to hold the car at stop. That's nice.
Another C240 behaived similiarly. Both of these were of '03 model.
thanks


Wonder if there's been any software updates on engine or auto transmission for 2001 c320 model?
