When pulling away and coming on to boost in 1st or second i hear the sound of a horn coming from under the bonet. What could this be? Car is a x reg classic.

I had a similar noise on my old car after fitting a fmic ,that was the dumpvalve

samcowrx

My recirc oe dv did that noise, stuck slightly open, are you losing any boost?

Phildodd06

Or is it the IC spray coming on?
Is your IC spray button pressed onto AUTO? If so, its activated when on boost, and sprays for about 5 seconds

classic_fletch

Not got an ic spray. So it could be the original dump valve?

classic_fletch

Just fitted dump valve and the horn sound has gone. Is there anything i can do to the original to fix i. I cant stand the shooshing sound

classic_fletch

My car still has the horn in the low gears when coming on to boost then changing gear. Could this be the actuator on my turbo?

have same problem with mine now for nearly a year , my car only does it when i have my vta dump valve fitted annoying but i have just put up with it

sounds like a cow mooing or something only happens now and again

classic_fletch

Yes cow mooing. I would be interested to find out whats causing this.

doshwrx2007

it states in the haynes subaru impreza owning and maintaining manual that it is caused by over filling with oil which clogs the wastgate soltenoid but i think its plainley down to fitting vta dump valves as when i put my standard one back on it doesnt happen my opinion anyway

at first i thought my car was fooked .

My car has no aftermarket dump valve but I too am getting this intermittent 'mooing'. Took it into the dealer and they couldn't find anything wrong, I'm a bit worried....
