Whistling noise
« on: September 27, 2012, 09:08:42 pm »
i was out having a bit of a play earlier today in my gti and when i accelerate hard in 2nd and 3rd - above 5000rpm i get a whistling noise like air escaping from somewhere!

the diverter valve was replace a few years back by VW....is this the classic symptoms of a faulty DV?

If so how much are we talking to get it replaced by VW?

cheers

The DV is the first place I would look. The Revision G is about £40 or the Revision D is about 50. Do a search on them both and make your own mind up on which one you want to get, I would say G. If you've an ED30, super easy to fit yourself, it's right at the front of the engine bay at the top. Here's a "how to" guide...

If you have a k03 engine it's a little more difficult to change. Plenty have changed it, have a look through "Search"

When putting my foot down over about 5k revs I too get a noise I didn't notice when I first got the car... Maybe I was listening out for problems as I had some work done on the car and didn't notice it before, my noise is more of a sucking sound... maybe the turbo? Or the characteristics of the engine...

I took it to the Indy vw specialist this morning, when linked up to the computer it had a DV fault code. He wiped it then we went out a drive cane back and no fault codes this time....

Think I will get the DV changed as even if its intermittent there is still an issue!
