Car headlights are flickering off and on while driving..

Started this evening on the way home. Also, car is feeling lethargic, like I have an anchor attached... Started this morning. I have no CEL or other warning lights...

Guess its time to call MB

if its just the lights flickering, you probably need a new Xenon bulb or the connection could be loose--this happened to me with my CLK when I had it.
It was within less than a year of new.
The lathargic part sounds a little strange and maybe unrelated--alternator?
call MB and get it checked out

Does sound like an alternator problem with the pulsing lights and lethargic performance (weak spark).

Actually I have had this before, it only happened twice, and I wouldn't have even noticed it the first time if someone hadn't pointed it out. 2nd time I definitely noticed. These happened months and months apart from each other. The headlights, not the lethargic feeling.

When it happened to me, it wasn't a flicker though, it turned off for about 1 second then turned back on. Not sure what happen, not sure if anything's loose but I tried to reproduce and couldn't.

Well, I have not had a chance to drop off the car at the stealership, but the good news is that I suspect the lethargy problem was bad gas, It's back to normal, and I recently filled up (and by recently, since I am doing 100 miles a day.. I am using alot of gas.. ugg). I will keep an eye on it, and avoid said gas station.

Bumping an old thread here, anyone have this issue on going? I thought I saw the last of it (it's been months and months since it's happened before) but it happened again to me tonight driving home.
