Revo Ceramic Intake - clonk noise!

[cupra_k1]

The "putting" noise sounds like the checkvalve in the rear PVC breather pipe to me.

Do you have a PVC revamp / catch can fitted?

[edition30jmr]

Nope I haven't got either fitted the car is completely standard apart from the revo kit!

Right then guys, Rich when the ignition is on but not engine when I press the throttle I get a click then once I release the throttle I get another click is that normal? And I checked the dv seems to be fine as does the pcv but I'm going to get it on a diagnostic machine for the sake of £50 and that will be piece of mind, oh and I tried it with the engine cold and it still does it then too, just thought id rule that out!

Anyone know if those clicks are normal?

The clicking will be the throttle body.

The clicking will be the throttle body.

So do you think the loud donk is the throttle body also?

Thanks

Hard to say, but I don't think so. Can't you locate the noise?

[edition30jmr]

I'm going to take the engine cover off tonight and have a good look and listen and try to feel in different places to see if when it makes the clonk if it vibrates or anything anywhere! I'm thinking of buying a VCDS cable so I've got one for future use!

Just asking but did you install the nylon washer on the bolt that secures the intake to the engine?

Yes and does it need any washers inbetween any of that? I used a washer the other side of the metal part (closest to engine) and another washer against the intake pipe after the plastic/nylon washer.

Thanks

As I said before.  Its the diverter valve.  Get a new 'G' on there and it will stop.  Had the same thing on a few cars now.

Doesn't cause any issues as it is anyway.

My S3 has always done this and its only noticeable when an intakes fitted.
I've already replaced the dv with a rev G and replaced the pcv but its still there.
On the Audi forum theres a few people mentioned it.
The noise comes through the intake and its not dependant on which intakes fitted.
Doesn't cause any problems and I only ever notice it when putting the car in the garage.

New DV Rev G fitted and it still makes the noise but slightly quieter! Hmm any ideas?

Normal
