    Default Service soon and limp mode after added coolant

    Hello all my car said low coolant the other day so I added a bit, immediately it when into limp mode so I though I must have put too much in and took some out. Now when I'm driving her hard she will go into limp mode and come up service soon.

    Anyone got any ideas?

    I've never had in limp mode before this

    Coolant was added when car was cold

    The question is why some coolant was missing ?

    Any change in level since you refilled ?
    It could be a leak somewhere.

    Did you add a lot ? only water ?

    Hi, I know this is unrelated to the coolant but the car going into limp mode and a message saying service soon when driven hard sounds like it might be your boost solenoid playing up. Maybe the bit about low coolant could be coincidence.

    find someone with a decent code reader to see why its going into limp mode but if it resets every time you turn the engine off then i agree it could just be the sub £15 boost valve
