Ticking noise???? WTF!!!!

[itsallgood]

Had a Gen 1 Apexi AVC-R installed last Thursday on Dyno and also had a tune and power run but after about a day of driving my car that felt brand new, i can hear a ticking noise coming from the passenger side floor when it reaches about 5 psi on my boost gauge. Don't get any power loss or gain just this annoying noise, was a little concerned at first that it was the turbo shaft coming a little loose but have had a few mechanics come for a drive with me and say that it isn't.

Spoke to the guys that installed it and they dont seem to think it's the turbo either. Any ideas of what it could be, am a little worried???

gasket leak possibly

Never goto those mechanics again, as they have ABSOLUTELY ZERO clue about the products that they install.

The ticking noise you hear is the AVC-R solenoid opening and closing, as it starts to control boost... Take your car for another drive... As soon as you start making meaningful boost, the ticking should start, because that's when the solenoid starts to control the boost levels.

The solenoid is mounted to your enginebay somewhere, and it "ticks" as it opens and closes because it's mounted against a steel panel. You could add more padding to reduce the noise, but there's no need as it doesn't affect the operation of the car at all(there should already be a thin sponge "gasket" between the solenoid and the steel panel)... In fact, the ticking noise tells you that the boost controller is actually doing something

HAHAHA... Owned....

In the instructions it says that mounting directlly on steel wall will cause ticking noise inside cabin. Suggestion was to mount up by air filter box or pad the mounting with double sidded tape etc....

Looks like they have studied the destructions (instructions)

Cool, thanks so much guys! Bit of a shame actually would have given me a reason to tell my fiance that i needed a new turbo

Will pad it with something over the weekend.

I have recently just had this noise happen to me. But it sounds quite bad when you floor it. Its from the Boost Controller I know cause it only happens when you go hard. And when you pop the bonnet straight afterwards and feel the boost controller its shaky just like the noise and thats where its coming from I think.

Why would it be fine and then just suddenly start doing it? Its mounted right next to the pod filter so I didn't think it would be this bad. If you turn the car off then on again it goes away but comes back after hard driving.

I hate saying this but it looks like Andrew has the goods here.

My AVC-R ticks a lot too on high boost settings. And it's apparently normal but I get your point, it is disconcerting if you were not otherwise aware.

Why would it suddenly start doing it though? It was fine before. Then suddenly it just happens all the time. Weird, grrr

[T0nyGTSt]

It only does it when you're boost up high. I can't get mine to do anything below 1.0 bar - above that however...

When you just idle is the ticking still there? Mine is there until I drive slowly for a period of time or turn the car off then on. It shouldn't be anything to worry about should it? Thanks!

[T0nyGTSt]

Nah mine is worse.

It makes a full on ticking noise when you power the accessories. That's just the electric power, not the starter motor.

1 out of every 10 starts.

Yeah I dunno.

I can hear ticking from my Profec, but usually only at idle. It's fairly muffled, being near my pod and inside the air box, so with even a moderate amount of exhaust noise I can't hear it. Even the stereo on at a moderate level will drown the tick out.
