    Slow traffic it starts to tilt to the right, also sometimes on the straight as higher speeds

    Yet start up it is level. ORM level, Newish bags

    Manual control via Hawkeye works.

    Also cornering seems to eventually relevel it.

    No faults on SLABS

    Can make cornering interesting when it can't make its mind up.

    Just when you've convinced yourself that it isn't the bags, it's the bags!
    You say "newish" when were they changed?
    My advice? Get a new set of bags on the car before you delve any deeper into the suspension system, otherwise you could end up over-analysing everything and just tearing your hair out getting nowhere.

    Bit expensive to fit a new set on the offchance, but at least you would have spare set on the shelf, if it wasn't the bag after all.

    Dunlop and I do not suspect pipe leak as still up overnight, unlike the originals

    Does it have ACE? If so remove R14 relay, and see if it still does it. If it does its suspension. Removal of R14 stops the ACE working, and puts it into locked bars mode, in case it is this. If it stops check the connections to /or the accelerators themselves.

    I can assure you Tony that @MJI is an ACE ace. However while he will no doubt thank you for your input, I fail to see how the ACE system could have an effect such as you talk of on the Self Levelling Suspension.

    Actually I will run Hawkeye on the G meters just in case as I replaced the ECU and did not recalibrate as it worked fine.

    Just in case it is trying to push that end down

    ACE is strong enough to lighten inside front on hard corners

    -0.68 was lowest seen, 0.5something highest on upper

    Parked on flat -0.02 upper -0.06 lower at one stage

    Upper went to -0.11 when it sagged at right rear

    Will recalibrate at near to work Tesco as flat

    Still the same

    Drops about 25mm or so, gap bigger both left wheels over right so very odd.

    Could it be broken tail or a something on front right spring?

    Both coils look OK, stationary right is half inch lower than left. Calibration wants blocks.

    I do not have the chassis blocks so want to recalibrate without them. I do have a jack and 2 axle stands.

    Another thing, is when I turned off the ignition before measuring the left dropped about 25mm

    If you unbolt the bump stops you can just use accurately sawn blocks of wood to calibrate.

    I use a tape measure ctr wheel to wheel arch. If you search the block number you may find the heights on the web.
