Pkelvin, you were the first one to refer me to this forum. Now you can see why I was so frustrated with my car. With this video to share, I hope some of you could shed some light on this.

ZF and MBCL had spent 3 months on it to no avail. My car is in the shop. They called me in monday to explain this in addition to the first explanation of rusting due to car washing.

I just received my call today confirming my meeting and apparently they briefed me on the meeting's agenda.

I will see if other forum people have experienced this if at all. No TSB ever issued.

Apparently, I was INFORMED today that this problem (despite repeated fixing) was a state of art and they were able to REPLICATE this problem on a few other R171s. Monday's meeting is to demo to me this so called Phenomenon. I wait to hear.

Now I am even more apprehensive that my new R171 will also have this feature.

To be specific, this phenomenon stems from the brake system and it was absent in R170. It supposedly can be replicated (at least for my R171) under the following conditions:

1. When the car is cold started
2. When the wheels, rear ones, are wet
3. When you put the car in reverse gear
4. When the car's disc has a small amount of rust or unsmooth surface

I wait to hear and stay positive. At this point, I have nothing to lose and rather be informed.

 

Handbrake shoes. pull handbrake on a little to see if it goes away.

you must be in hongkong because the car is LHD.

the noise is coming from the brake.

it sounds like the friction between the pad/lining to the rotor/drum.

i think the problem can be solved by modifying the brake caliper or other brake components.
