boost control solenoid always clicking. why???
my 96 wrx boost control solenoid is always clicking, even when idling.
from what ive read it should only do this under boost.
does it just need a clean or does it sound like there is something seriously wrong?

Has it got a remapped chip in the ECU i.e does it run more then 13psi of boost.
I have seen this quite alot on the U8, 2C and W8 ECU's if the code and duty maps are not matched.
Although your car should have a Z4 ECU which shouldn't suffer exhibit this problem.
either that or the throttle position sensor/switch needs a slight tweak so that the switch comes into action when the throttle is closed.
This is mounted on slotted holes, so there is a degree of adjustment.
