Well 4 weeks all good, and then today the blue code is back, and getting overflow reservoir, wonder if its an air pocket? Might flush the system and see what happens

I had this type of problem, just a guess but I'll bet it is an accumulator or pulsation dampener. If the ride is rough I'll bet on an accumulator, if it's not rough I'll try the pulsation dampener. Before a flush I'd try to drive the code out having adequate fluid and pressing the button a lot. When my dampener went out the dash display went to "no Codes" soon after refilling . Members say it makes a hum noise upon a dampener going out but for me not so. I did not know what part failed to cause the overflow till I pulled it out of the wheel well and dropped the screwdriver down it. Hopefully the pump is still fine and pressure is good after refilling the fluid. I'm betting the new pump was hard on the old pressure reservoirs.

White (blue) warning could be many things though, I'd check the codes first just to be sure, but another rodeo (actually, pitch front and rear is more thorough for bleeding) can't hurt, if something breaks during the procedure it was gonna die soon anyway.

I have replaced the front and back accumulator, the only thing I have not replaced is the front dampner behind the rear wheel and the pressure switch. I will see what happens, it was fine until I had reposition a rear valve block line as it didn't seal(it does now).....I am thinking maybe I have an air pocket somewhere...

I had the same problem with a 2004 SL500 and the Troubleshooting ABC problem on Youcanic helped a lot. Here is the link: https://www.youcanic.com/wiki/merced...nsion-problems
