Never before seen leak. Need advice or will buy a Valve block CL55
So recently my ABC state in leaking from the valve block, more specifically the valves/syloniod area. I will post pics. It's odd and hard to explain. But if somebody could possibly tell me WHY it started to leak there and also HOW to fix it/ take the Valve apart from where it's leaking.
There was an O-ring sticking out of the valve and you can squish the valve down. Hence where the leak is at. I do my own work but am stumped on this particular job. I just can't seem to figure out if I can take the valve apart. In the pics I attached where my finger is pointed I can press is up and down on BOTH valves.
Any advice is appreciated. I'm also new to this MBWORLD so take it easy on me. I have been on EVERY thread(I think) about ABC. If not send me a link! I will also do a COMPLETE write up with pictures and detail when completed. I'm active so I will respond ASAP
Thanks- Max

Yeah I am stumped. But somebody on here I know has ran into this problem before. I thought it was the reservoir at first ( I wish, $80) and now I'm stuck with this leaky valve

keep us updated. love to see your write up with pictures. there is a u tube showing this, but not complete. do a search, there are also guys who rebuild them, on here and ebay. i think the hardest job is getting it out. you should be able to rebuild yourself if you get the proper instructions. it appears that your missing a top piece on the solenoid your pointing to, but i've never taken one out, only looked at pictures.

So I stopped at Evans Automotive in Columbus, Ohio.. What an amazing place. Maserati's, Ferraris and all types of AMG's just lined up getting their regular maintanc.. Anyway, I spoke with a fellow named Nathen and after looking at his schematics on the Front Valve block we concluded that you can NOT really get the pressure Sensor apart.. ( PS is what my finger was on in my pic) we also cross searched the part # and EBay has some for much cheaper. The valve block is $2,000 from a dealer and the Sensors are also a little less than $2,000. So there is a place I found called COimports based out of Colorado. I am pullin the trigger on buying the entire valve block and all sensors (rebuilt) for $400!!! they also give a 60 day money back warranty. So well worth it. I will keep posting to this thread with every step I go. Hopefully it all works out and somebody can gain knowledge/help as well. This is a real pain trying to track down parts for these that are cheap.
Also if anybody ever replaces the valve block, it's easier to take it to a dealer to go into "rodeo mode" where you can flush the system. It requires some special scanners. We also concluded at EVANS that my PS busted because of Dirty fluid. Hope this helps.
