The Stoptech website covers modern brake theory very well.
Here is the bed in procedure but if you go back to Technical Information all of their white papers are excellent.

Knocking on turns...
I have a knocking noise that occurs when turning. Anyone else have this? I've only noticed at low speeds, and only at a certain degree of wheel turn occasionally. The tech at the dealer was able to replicate the issue, and I'm leaving the car there next week to fix. Disappointing on a brand new MB.
I also notice some scratches on the wood paneling in the car, that the dealer said they'd replace. On delivery, they seemed like smudges, but turned out to be scratches.
It's definitely disappointing to have these types of issues on a new car, but so far, the dealer service has been great; at least in terms of what they say they will do, as nothing has been done yet. Honestly, I hope the actual service works out the same, as I would love to have a working relationship with a dealer close to me; so far the signs are positive, and they come across as honest hard working folks.
I will update again after the actual service is completed.

Same scenario on the noise for you?

Slow turns at almost 90 degrees for you? It's a dulled "knock knock knock" only at certain degree turns; also inconsistent. I've usually noticed it turning into my driveway. They initially thought they knew what the issue was, had to do with fluid transfer on 4MATICS, but the soft fix didn't seem to work this time. Thus bringing it in again next week. I'm just glad they were able to replicate the issue, as I was previously.

You don't mention what location the knock seems to come from. Is it effected by fuel level in the tank? With W203 & W204 a few critical users hear a distant knocking that was traced to the dual fuel level sensor units under the back seat. 203 & 204 had the castor bush issue & sometimes soft rear tranny mount that caused knocks in certain conditions. It can be things as simple as exhaust routing & fitment.
With W205 having seen a complete suspension redesign even with steel underpinnings we don't yet know of potential minor gremlins.

I took a brief drive this morning and didn't notice anything this time.

Hmm! that could be many things including the rack mounting bushings. It will be interesting to see what the dealer diagnoses.

So, about people visiting this thread, half of them had problems with their new C-class ?
But maybe many didn't vote ?

As production continues, there will likely be fewer of these small issues popping up as the sources of the problems are identified and rectified.

Remember that forums concentrate complaints or issues. Some people only post when they have an issue.
Obviously a thread like this even more so.

Regarding the complaints about odd noises when turning the car at low speeds ....
... this may not be the cause of the problems mentioned at all, but there is a common problem concerning low speed turns with low profile tires. It is most pronounced in colder temperatures, and it is tire skipping. When turning slowly with low profile rubber, the tires can actually stick and then shudder or "skip" as they turn. This occurs at very low speeds, typically when parking or starting to move.
Again, this may not be what is actually happening here, but it is a very common complaint with cars equipped with low profile tires.

Just helped my sister pick up a C300 yesterday. Saw a few on the lot that still had really bad gas cap fitments, but her's which arrived at the dealership on Dec 24th had a perfect fit. I guess they fixed the issue already with later builds. However, the "radio" font still sticks higher than the surrounding buttons.

Its the top edge of the cap that doesn't stick flush right? Stan made a thread about it. Apparently, the cap cannot be adjusted and the entire cap must be replaced. He said the replacement was better but not perfect.

Yep! Pending means the number of times triggered is below CEL threshold. Hope they fix the issue.

The Xentry diagnosis used by authorized dealer is totally diffrent from cheap ODB readers, Xentry cannot use or translate the codes presented by other systems, so dont be surprised why your dealer cannot use your data.
