Was taking a right turn at around 20-25mph when I clipped the passenger side rear wheel. I inspected it after, no cosmetic damage on the rim, have yet to take it to a tire shop because it wasn't flat. Car seems to drive as normal.

The problem: below 20mph, when Im pressing on the brakes, the yellow ESP exclamation point starts flashing 3-6 times and goes away when I come to a stop or depress the brake pedal.

After we checked the codes in the star diagnostic system, it just gave us a generic SBC ESP error, I think it was ABS error 6210.

We changed both rear speed sensors just less than a year ago.

I'm going to take it into a good Mercedes shop on Monday for them to diagnose... I also want to do an alignment because Im sure it's off, but again, ESP light when pressing the brakes only under 20mph? Really damn specific. Some people are saying brake lamp switch? (It was never replaced for the life of the car).

Any help would be greatly appreciated.

Did you also check the ABS rings on the rear? Those things deteriorate over time

Plutoe

did you double click on the fault as that would have told you what to test next

we replaced those rings when we changed both rear speed sensors.

I plan on going more into those faults tomorrow

Brake light switch is a easy swap and costs about nothing. I would recommend to swap that out anyway.

Did that yesterday, didn’t fix the issue

For anyone ever coming across this issue... ABS speed sensor rings were replaced and problem went away.
