hi friends,
recently , i changed all accumulators and there is no more ABC errors
but driving quality is getting worse again , i guess,,, front valve block's aging or pipe problem .

ABC pumps pressure bar is about 190 , dealer shop says it's in perfect condition .

i attach front left's pipe

rear one's had no problem at all.

As you see, green square and blue square have fluid leakage.

thank u !
i wish all u have good weekend

190 is a fine pressure. here are the diagrams for the front hoses. I can't quite tell which ones you have marked based on your pic as it is too close up. If it is the 2 going to the pressure relief valve they are about $90 each from MB, but you can also take them to any hydraulic shop and have them rebuilt.
