fix the fault

The Check Engine light is there for a reason. Something has gone wrong.
Take it to either a Mercedes dealer (expensive) or a good independent (better value, use the forum search function on the Mercedes specialists across the UK forum). They will put it on a STAR computer (MB's own diagnostic system) and give you the good news

I logged in looking for my issue and your question was somewhat relevant. My light came on at the weekend and the engine has two new behaviours.
At low or know trottle it will intermittently surge or pulse.
And now I have no kickdown and the engine is limited to about 2750 revs
CLK 270 cdi auto

i had the no kickdown issue... it was put into the diagnostics machine and it said that the emissions from the DPF was 2 high and the mechanic said to drive in the motorway for about 30 miles with a constant speed over 60mph..
i did that and the DPF' regenerated' so it started working normally again...
if not fixed it could be the MAP sensor or DPS

It could be many things causing it so no good guessing, just get it on a diagnostics machine and turn the light off then see if it comes back on.

true...bottom line: withouth a diagnostic we will just be guessing what it is... get it plugged into STAR it will be £30 well spent ... well it was for me

yeah, I think so. but I want to do it by myself first. If the problem sitll not be sloved, I will take it the professional car repair shop.
what is kickdown? I am not professional with that.before diagose, somebody told me that the check engine light is not actually an engine problem, it also may be O2 sensor, MAF sensor, fuel/air ratio, pyrometer or exhaust. but I put my om580 code reader to check, I got the fault code P0411.
ok, thanks you share your experience with me, I will do what you said if the check engine light is still on.
great, thanks Stratman.
