    hi ive been having a reacurring 17705 code coming up. it takes about 4 days to come back once erased.The car doesnt seem to be driving much diffrently appart from what feels like a slight miss in the engine sometimes.i havent had the car all that long so i couldnt tell if there is a power loss.
    any ideas guys?i know its a loss of pressure code but ive had a smoke machine on the engine and no signs of a leak anywhere?
    please any advice greatful

    diverter valve seems to be a common one. also a few pipes under inlet manifold which are prone to cracking

    Have a look in that link i posted matey. It has causes and solutions in there. 1 of the main things to check is the dv as mentioned above.

    Could be woth checking you havn't split any pipes when fitting your dv, could happen by overtightening jubilee clips! some tool I know done this! :undwech:

    yea they look fine and there was no signs of a leak when the smoke machine was used. its weird that if i erase the code now it will take a few days to come back on?!ill see if i can book it into a garage. a boost gauge would be handy wouldnt it.
