I have a sti typre R and when i accelerate the wastegate controller ( small cylinder thing on left of engine) or cellunoid makes a ripid clicking noise that can be heard from within the car, is this normal???

 

Get this on my MY98 also but not all the time. Mostly notice it a very light throttle openings ans at low revs. Also it occassionally runs on ticking for a second after the engine has been turned off.

 

yeah thats it. Any idea if it is a problem that needs to be fixed.

 

No idea mate.

Mine has been doing it since I bought it nearly 3 years and 30,000 miles ago and it's still going OK (he says looking for a bit of wood )

 

*passes scratch some 'wood'*

 

Damn noise. really winds me up. Just have to turn stereo up louder...

 

Cheers for the piece of wood Trem

 

Sorry its so small

 

mine does it too, MY97 wagon. samll solenoid thing just above/next to the air filter. on the left wing, does exactly the same as yours & carries on a bit when you swith the engine off too, not bothered too much though as it only does it every now & again.

 

could be injectors ticking away

 

It’s your boost solenoid, its suppose to tick… so don’t worry. Worry if it stops though

 

the fact that its ticking loud enough to be heard in the car could that be a bad thing? is it worth replacing? what could happen if it dies????

I’ve not heard of anybody’s totally failing but I’m sure it’s a possibility. You can clean them out every so often (you will find out the procedure if you do a search) But they are supposed to tick. You can mount them on a bit of rubber or sponge to reduce the ticking in car. I’m sorry I don’t know what would happen if it stopped working.

 

cheers i'll try some magic wd40 & see if that helps

 

I questioned my noisy Boost control solenoid. Its normal as already explained, but i changes it for a second hand one which is a hell of a lot quieter.
