Hi everyone

I would like to ask for help
I have w203 with illuminate 2 fault code on instrument panel
BAS and ESP fault

I scanned it with STAR and here are the codes
C1050 ( component N65/3 brake booster vacuum pump faulty or lead open circuit)
&
C1185 ( A7/7b1 BAS diaphragm travel sensor electrical fault )

So far, i changed BAS diaphragm travel sensor, and then check all fuse were OK. but both fault code still remain.

I tested it with STAR diagnostic to see the status relevant value of BAS diaphragm sensor it come out 0.000 value (but brake work normal)

Anyone can help me, please ?

Thank you

I fixed the BAS warning by clean the brake switch attached to the brake pedal
