Fluttering noise
« on: 18 May 2009, 12:17 »
I'm new here so pardon my ignorance  :wink:

I got a golf mk4 1.8 t nearly a year ago now and always had a fluttering noise from the dump valve when changing gear. I thought this was normal but was told its boost surging and can damage the turbo!!! :huh:

Was told a new dump valve would sort this out as the crappy standard bosch one don't last to long and can fail. So I was gonna fit a forge split-r anyway so went ahead and bought one and fitted it, but still getting the flutter and need help?!?!

Either I've been misinformed or something's up???   :undecided:

The split Rs can cause problems on some of the 1.8T engines your best off with the Forge 007p thats what most people on here use.

yeah I was in 2 minds if to get the split r or the 007p but went with the split r because wanted a blow off sound.

But even with the new valve on now I shouldn't get the fluttering should I??

Might have to purchase a 007p see if that sorts it out

Apparently if you contact Forge and say you have been having problems with the Split R and poor running they will exchange it for the 007p. If you want the tssssh sound fit an induction kit with the 007p.  :cool:

my bosch one used to make this noise too, i quite liked the noise tbh, i thought it sounded cool..lol
i have now changed to an R-spec one, not the most expensive but does the same job as the more expensive ones..

lol i quite like the noise to but if it's not spose to then it's gotta go!
So did it stop fluttering with the r-spec one then?

I'll get in touch with forge see what they say and get this sorted out.

Next stop induction kit slowly getting there...................!!!

means you need to replace the recirc valve, it happened to mine, luckily my brother had his one from his s3 sitting in his garage (he uprated his to the forge) you shouldnt really drive it like this, as the turbo is stalling?? i felt the difference instantly power wise, the second it went, i thought i was driving a 1.1 golf haha
