Should I be worried at all...
Should I be worried at all...
Off the top of my head I think it's something that happens more when the A/C is working hard (in hot weather).

Mine does it more often than that, more so that I don't really notice it anymore. I'll try and pay attention to it and see how often if does it.

It is weird tho, because I cant say that even when I move from Park to Reverse/Drive and the idle drops from 2000rpm to ~600rpm I feel any change in the brake pedal. So probably not directly related to idle turnover?
Hmm I cant recall whether I had my AC on or not. Certainly wasn't a hot day, but I do often have it on to prevent the windows from steaming up.

Our Merc does even weirder stuff like you can hear what sounds like a motor whirring when stationary occasionally so no idea what these cars do while they're sitting still!

Yep it's not related to the idle itself, I think something changes while stationary that increases the load on the engine which makes the idle drop (and somehow also affects the brake servo I imagine).

Fry-Up ah yours idles at 2000 rpm too, I was always curious as that seems high and my 200 didn't idle that high even when cold, but my 300 does for a minut when first started
Yeah, cold starts at about 2k and slowly drops over the course of about 30 seconds. Normally before it settles though I've shifted it into gear and it instantly drops to around 600-700.
Although not directly related to this thread, I've seen lots of good words said about seafoam engine cleaner over on my.is, and how it helps improve idle + gets rid of some little niggly running issues. I might give it a shot.
