Question Boost control solenoid ticking / clicking

Last week a loud ticking sound started in my car. (about the same time I re-routed some hoses for a boost gauge.)

Today I figured out the sound was coming from the factory boost control solenoid. When it's unplugged, no sound. Plugged back in.... Tick tick tick.

It appears to be only at idle. As soon as i put load on the engine, it goes away. It doesnt appear to increase with RPM's... My wife noticed the ticking too.

-05 STi 3600 miles
-Utec Stage 1
-No ABC
-I have 1's in the boost map untill the 60% column.
-Boost gain set to 49

Has anybody else experienced this? I guess I could take it back to the dealer but i want to avoid them accusing the aftermarket parts for causing it.

i am having a ticking / clicking problem with my BCS either. I am using Greddy Type-S ebc and greddy boost selonoid is making the same noise after 0 psi. I would like to know how to fix it.

I dunno about the stock bcs(even though I would think that it's the same as aftermarket solenoids), but aftermarket solenoids are known for making a clicking sound(as far as I know). This is normal, since it's venting air from the wastegate actuator tubing to prevent the wastegate actuator from openning the wastegate and limiting boost. As always this is just from what I've heard......

peace

well i don't think that this sound is normal. It is very loud and annoying. I am sending back the unit to let them see it. I'll post the results.

get rid of the 1's in your boost map in the zero col. clicking will go away. the oem ecu keeps the bcs completely OFF, whereas the utec only pulses at very low duty cycle. not the same thing.

Sorry, I should have updated this thread. It was the 1's in the boost map. As soon as I changed the 1's back to ECU, the problem immediately went away.

If the problem is hearing the clicking at idle, you can obviously put ecu in the 0% column below 2000rpm. You obviously wanted to accomplish something by using 1 in your boost map though, so you might wanna leave it in the rest of the map where ya had it b4. It's not like the bcs doesn't make a sound while running normally(like while building boos), ya just don't usually hear it while the car isn't idling........

peace
