s2 still makes strange noise

[Erikb]

My car still makes a strange noise when it reach 4000rpm, I keep the noise till 5500 rpm then it is gone. Is sounds like the noise when you use a open air filter.

I havent got the plastic air sucking pipe that goes to the front light, at the moment the air is sucked next to the turbo. I know this cant be good, but I am still looking for the part. But I dont think this can cause this sound. Is it possible that the MAF sensor of the Lambda sonde can cause the sound. It also doesnt run smooth when it is in idle.

The car isnt tuned, and runs on 0,65 bar max.

thanks in advance ,

boost leak mate - I would guess the hose to the throttle body since you can here it- usually underneath.

Ok, thanks Doug. I will look into it.

You got it. Does the noise sound like its from behind the dashboard??? I had this. Also stock 3B should boost to 0.8bar

Yeah it sounds like is is coming from behind the dashboard. I checked all the hoses there and most of the clamps i got a bit tighter. I havent tested it. I also got the wastegate cap off. I wanted to make the spring a bit tighter, but I dont understand how you can do this s, can someone explain this

thanks,

Erik

You dont want to be doing that on a stock car. No way. It will be the the hose going into the throttle body, where the idle speed valve goes in. These split underneath and you cant see it. You need to take the metal black pipe off and remove this hose. I will have split right next to the clip.

Does someone maybe have an etka picture of the wastegate?
