SBC Braking power reduced. Press fully.
Hi everyone, I’ve been a long term follower of this website and you all are just lifesavers. I’m getting this SBC error on my third C219 but what’s confusing me is that I have good pressure in my brake accumulator(around 162 bars) but I’m also getting code C2131(pressure reservoir faulty). I have also checked all the pressures and they seem to be ok. I also have service brakes on my dashboard. Please see the attachments

Do a visual check on the accumulator, does it has traces of fluid around the connection on the SBC pump?

no leak around accumulator but I have noticed a few of the line connections are oily around the joint. Is this the issue.
