I think the stiffening suspension is urban legend. And I've never seen any option package listed that would allow for it either. However, it might be time for a reminder for the new owners on here who might not know about it about the ability to reset the memory on the adaptive trnasmission. Now that really does make a difference. I did it yesterday for the first time in a while.

2008 CLK 550
I reset the ecu and what a difference.
___________________________________________
My vehicle has only 3,700 miles on it...
bought it with just 1,800 miles on it at the beginning of the year.
Had been owned by an older man that passed away and his widow stored the
vehicle since May 2008. Still had factory cellophane covers on the mats, not
had its first service... like brand new.

I expect the vehicle had never been driven briskly...which makes sense.
No way did I ever think it was "sluggish" BUT now...
There is the thread on this reset... https://mbworld.org/forums/w211-amg/...set-works.html
___________________________________________
What I did worked:
Get in, CLOSE the doors and windows...
insert key and turn to second position...full lit display but NOT start...
depress gas pedal to floor for minimum 5 seconds...HOLD
turn key back to insert setting THEN release gas pedal.
The original poster stated that the reset needs a minimum of two minutes.
I did not know if this meant leave the key in situ and don't open the doors or
windows for two minutes OR that you could leave the vehicle and it would take
two minutes to reset.
Being goofy, I chose the former option, just in case.
Anyway....IT WORKS...unbelievable..!!!
Many thanks to the original poster - Jakpro1

I used to love dyno mode on my last C230k.. Until a big chuck of the rear differential pinion gear broke off. Haven't played with it on my CLK350 yet.
Question, I noticed someone said to set it back before bringing the car in for service. Dyno mode used to only last until you shut off the car. Has this changed?

It will default back to standard on shutting down & rebooting by starting. The event will be recorded for a while.

I would not do anything to jeopardize my warranty nor indeed the reliability of the vehicle.
The 5 second gas peddle reset DOES perk up the transmission setting quite noticeably; although my usual driving habits will no doubt have it reverting to "sensible" setting very soon
Merry Christmas to you and your family.

Since we're on this topic.. has anyone ever done any comparison in fuel milage between S/C modes? I notice when in comfort mode going up a hill it will try to stay in gear at the low end of the power band. When this happens I notice the mpg really goes down on the display. When in Sport mode it will downshift right away and go up the hill at a higer rpm. I would tend to think higer rpms would yield lower gas milage but can't be 100% sure here.
Back to the question, has anyone done a real comparison of mpg between the modes?
