Hi. I have a 2003 E240 and got the service brakes warning. Deactivated SBC, Depressurized, Changed the pads and bled using the MB Star Diagnostics and came up with a C2131 (Pressure Reservoir Faulty) code.
Changed the Pressure Reservoir as advised by the MB Star and also after reading some forum posts to confirm that this should be done but still we are not getting the fault cleared.
The old pressure reservoir had a "pretensioning pressure" of 64 bar... Specific values should be 72 to 102 bar.
The NEW Pressure Reservoir is only giving me 62 bar. We've bled using the Star and also a pressure bleeder but the fault and warning are still there. Does this need to be programmed or something?
Thanks in advance for any tips or recommendations.
