    Bugger...new accumulator fitted, bit better but not much:(.
    Pump runs 2nd pedal press rather than the 1st.
    Ignore and hope it fixes itself or....o_O

    No fluid came out when removing the old one btw. Maybe it needs bleeding again ?

    I'd dribbled some fluid into my new accumulator with it upside down before fitting. There was a little seep when I fitted it but not much. Only firmly hand tightened, but I did notice it was just weeping from the accumulator mount after a few applications, so I gave it about an extra 5-10 degrees of tightening with the strap wrench and that stopped. No issues since with it, apart from the telling off when I checked on the first drive that the brakes were better and SWMBO got a bruised collarbone as a result.

    I'm sure i read earlier in RAVE, accumulator ships at 80 bar, minimum pressure should be 50bar

    Possibly not getting pressure from the pump? Pump not pumping or that valve playing up.

    As said, air in the system will affect it.

    What valve is that?
    Pump pumps when I do the brake bleed.
    Out of desperation I'm going to do a full bleed again this morning.
    If that doesn't improve things what would be my next move?
    Anyone got a known good accumulator I could borrow incase my new one is faulty? Just to eliminate?
    All costs covered plus a drink:D

    I was told i didn't need to bleed, just swap.
    Mines by no means new, pump comes on during the fourth pedal press. Might have fitted it in 2016

    Check your flexis and callipers aren’t weeping anywhere and bleed it, always worth a try with these. I thought I’d got away with just a top up until I started driving around.
    New accumulator won’t hurt, should just bolt off/on no bleeding.

    Just bled it all again, no air anywhere just lovely new brake fluid.
    Following the manual word for word too. Something I did notice, the manual says to only use the lower 2/3rds of the pedal travel when rebleeding the front calipers after the modulator/front calipers/modulator/rear calipers, when the bleed nipples on the front calipers are opened, fluid flowing, ign on, the pump doesn't run, I suspect that's normal though.
    Been all around the system, no leaks.
    That's why I'm mentioning the above front caliper thing, massive leak(bleed nipples open) but pump doesn't run .
    Not tested it yet, decided to have a cuppa then try it in a bit.
    Edit to say, no leaks anywhere, all calipers, flexies new.
