Hello! Guys, i have a problem. My c63 have not a big knock from the front suspension when passing rough the road. Checked the suspension arms are all well. Official dealer can't find the problem. A knock is heard only on low speed. What could it be? Suspension with springs H&R (Springs are installed correctly). What to check, where to look?

Could be the engine mounts.

My car have a mileage of 17,000 kilometers. Can be the engine mounts so quickly deteriorate?

At that low 'mileage' I would suspect not. It was just a thought as your description somewhat matches what I experienced when my mount(s) went bad - at about 55k miles. Keep digging into other cause but keep this in mind. If you get your car up on a lift then you might as well look at the mounts just to be sure. GL
