DV going bad??

[Aleks]

So, now with my mew intake I began to notice that I get sounds when accelerating (at any throttle w/boost) that are similar to blow off sounds, just like a constant noise...then ocassionally I can lift my foot off the throttle and burp it again, and the extra pssshhhht noise is gone (you can actually hear it go shhhhhhtpppp) and replaced with the proper clean turbo whistle...Almost like the fluctuation in pressure causes it to seal better....I also get a little more oompf out of it when its not "leaking", but I don't see anything different on the boost guage, still spiking at 14ish and holding 12-13.....Its not honking though, as I've heard they can do....anyone else had this problem, and maybe have an extra DV laying around?? I want to buy the forge, almost did the other day, but wanted to see if this was actually happening to me...Oh, and does the forge sound better than the funny factory DV sound?? I hate that horse like sound....The car has 40k on it now.....HELP!

Those sounds are normal, from how you describe them. Loud sucking noise under throttle is normal for CAI I think. Boost gauge will not be affected by CAI or intake.

If its not honking, and boost is the same, its probably fine.

pretty sure its just the CAI. i was amazed too when I first started it after installing mine, it has a loud sucking noise coming from the drivers side from the open air filter and then if yo ulet off throttle a bit it does a mini blow off.

I had to get the DV replaced on my old GTi - it was making sounds best described as 'fluttering'. If you're not hearing that, I'd say all is normal.

I replaced my DV a few months ago.

Symptoms:
1. Car would often go into limp mode (only 5 PSI) after a few minutes of driving.
2. CEL: Don't remember the exact code, but it was DV related.
3. Never got the honking noise, but would occassionally get what I would best describe as a creaking noise when I got off the throttle. Thought it was the suspension at first, but it would do it in 4th/5th gear as well when there wasn't so much loading/unloading of the suspensionwhen I got off the gas.

Re: DV going bad??

Hmmm, I'm unfortunately still not impressed by the whole thing.....its just not a good sound, and its not a sucking sound I'm thinking I'm hearing, and the sound is fluttering (good choice of word!) when it blows off.....I'll still weigh out my options, and probably buy another valve....

Re: DV going bad??

Are you getting the fluttering at part throttle or WOT?

[Aleks]

Re: DV going bad??

It does it at both, and sometimes not at all.....

Switch to a forge and you'll be fine =)

Hmmm, I get something similar to what you get every so often but I've only noticed it at part throttle. It happens to me under acceleration only.

Re: DV going bad??

The fluttering sound I experienced came when I lifted off the throttle after having my foot in it.

If you're fluttering at all, then your DV should most likely be replaced.
