This story has nothing to do with your MB's ticking but had a similar sound in my '72 Cadillac Eldorado.

Everybody who heard it said that they could fix it: Some thought it was the brakes, so after new calipers, pads, fuild, etc. it stilled ticked. I had to pay for the two calipers, the rest was free.

The pinnacle of this story was this: a transmission shop were sure that it was the tranny, so they guaranted that if a rebuilt tranny didn't fix the problem, I'd have it for free (just for the material).

As in the other cases, I told them that I thought it was in the engine but they were adament about the source being in the tranny. I will never forget the faces of the tech and manager as the car was started. The manager was in the back seat with me while the tech was in front. As soon as the car started, there was that 'tick, tick, tick' noise. Needless to say the car had a new tranny for $150 or so.

What caused the tick??? This is the sad part. About six months later as I was driving up a very steep hill (about 3 miles), the tick turned suddenly into a crash, smash, etc. One of the connecting rod's screws was loose (that was the tick) and it continued to work itself out. Finally it fell out and that was the end of this tune! Sold the car wholsale (about $1000).

Hope your story has a much better ending!
