Just found this fault code after using vag-com,17956 boost pressure regulation valve(n75) open circuit,can any one shed some light on it newbie to this sort of thing to.how do i clear the fault code using vag-com.

Thanks in advance

Take a look at this http://wiki.ross-tech.com/wiki/index.php/17956/P1548/005448

Is there a way of checking the N75 valve,i've just changed the diverter valve can this cause the fault to appear aswell.

Thanks
