Last week or week before i did the N249 bypass....

now then as far as i can tell, i have checked all the pipes are in and there are no boost leaks at all...

the DV (forge 007) now sounds different....almost a flutter......when you lift on.....rather than the nice kinda darth vader breathing sound it was giving out.....mind u it does still seem to give that when accelerating its when u let off, u get a kinda of fluttery sound.....and ive heard this is bad...

Ive done a Vag.com scan and nothing came up apart from a excessive boost error which i have cleared and now seems to be ok.....

Any ideas or do people think everything is ok?

kink in your hose on top of DV?

check and recheck all your hoses, if it wasnt doing it before you bypassed it and it is now, then somthing is wrong, check for holes, kinks etc etc...

you have done it right as well havnt you? any pics?

Sounds like the dump valve isn't doing its job properly, as Dave said double check all hoses are free of leaks and connected properly. Are you sure its plumbed in correctly also is the little black and white check valve in the correct way round?

Might be worth doign a leak back test on dump... but would agree with others, if it wasn't doing it before and is now... check all hosing and connections are correct...

Have you checked that the black/white one way valve is the correct way round?

Right here are my pics...

I have checked all the piping and connections and moved things round a bit and it does seem to have made a little bit of difference. Not fluttering now, just dumping loudly :)

But here are the pics just to double check ive got everything done properly...
