Sbc Rebuild W211 is it really works
That said, yes. The system needs to be reset via STAR. Plenty of reading on the subject in this forum.




Look for the information listed below using STAR. These numbers are from my W211's last service; the numbers indicate I'm still good but need to monitor more often rather than waiting for the red stop sign of death to appear on the instrument cluster. I would bet your remaining pump life is zero. And there is a good chance that the pretensioning reservoir pressure is below nominal.
-Brake system actual values:
-Bremsenzaehler (brake system solenoid actuations IIRC) – 301,454
-Pump cycles – 11,224,600
-Estimated remaining pump life in % - 23.2% (DJ_GetPmpLD)
Get to the above values by this route:
-Control units/Chassis/SBC sensotronic brake control/Development data/Actuations/Complete index of Actuations
The pretensioning value will be found under actual values under SBC folder.
-Pretensioning pressure in reservoir – 73 Bar (72-102 optimal)
