s211 320cdi ESP ABS message

[astamir]

Hi guys!
Needed a help from the forum members who experienced this kind of problem.
Three messages appeared on the dashboard ESP ABS AND BRAKE PERFORMANCE REDUCED with yellow abs sign on dashboard.
Plugged Delphi diagnostic tool and it gave me the following codes
C2534-hydraulic fault,right front separating valve.
C225c-unknown
C2412-left front speed sensor, carry out visual inspection.
C2235-inlet valve LF
C140-Front left speed sensor
Permanent
C14be-system faults:test SBC control module.
Permanent.
So far replaced the front t left abs sensor and brake switch sensor and here the description of the fault, after you start the engine and stay stationary nothing comes up.
As soon as you start driving first yellow abs sign then the messages appears, before they appear,you can feel something going on on the left side at the front wheel and then the messages comes up.
Sometimes before they appear the yellow triangle sign flashes with the action on the front left corner and then the messages comes up.
Can anyone help me please ?Would be very much appreciated.
Thanks

Reduced breaking, is that not an sbc fault?

SBC fault would give the red stop the vehicle sign with sound I guess.
Cheers.

I found a thread online of the guy who had the same problem and the abs ring was a problem on his.
Going to try this just wondering if anyone had the same problem?
Thanks

If the abs resets and the fault only comes on when the vehicle moves , it will be one of the speed signals abnormal or missing .

Since you changed the sensor it will most likely be the reluctor ring . Sometimes cleaning them helps .
