Pressure Drop!! Help...

[Aviry]

Hi guys my name is Omry and im from Israel (think im the only one from israel here), i drive a 2004 seat leon fr (180).
mods s far = KN inbox filter, "Frilling racing" remap and a boost gauge.

in the last weeks i noticed a bit less power, i went the a my garage and got it checked it with VAGCOM, there was an "Pressure drop between turbo and throttle valve (check DV)" fault.

so i was happy, no big deal, only a damaged silicon hose or something like that.
I WAS WRONG!
No air getting out of no where when we check the system under pressure...
and still after we cleared all faults, 1 min of driving and its coming right back.

I think its the DV (i have the original "Bosch" one) am i right?? should a new Forge 007p or splliter solve the problem?

And another question. when i turn my Leon on after a long time (more then 5-6 hours) it terns on in limp mode and i have the turn it off and on again. is it because of the fault of pressure drop i've got, because no one heard of this problem here?

Thanks for helping, Omry

I'd suggest that perhaps the standard DV is leaking with the increased turbo pressure from the remap

 

[Aviry]

the remap was 2 years ago, so its possible. but the remap is a solid one and not so aggressive as the revo. only 1.1-1.2 BAR. is it still possible?

 

[Leigh15]

More likely to happen as the valve ages I would imagine

 

[Aviry]

please anyone?!?!?!?

as Leigh says my thoughts are that it's the DV to be honest, they're know to be fragile, and when the boost is upped even more so!

upgrade the bosch dv! 1st thing i suggest

 

[Aviry]

ok its the first thing i'll do but do you guys think th other strange problem of limp mode will stop too???

Its difficult to tell until you elimate this problem
It won't do you any hard to upgrade DV

 

[Aviry]

im sure im gonna replace the DV just not sure if im gonna put the 007p or the splitter, are they any differences besides the noise? i wont my DV to hold the pressure and my car to go faster, dont care so much if it has a "whoosh" sound or not...

 

[Willie]

Price and noise
007p worked well for ages so no reason why not use it
I'd go for this over splitter
Gives you more money to spend on other things

 

[Aviry]

10x 4 the quick answer! i'll post here again if after the upgrade i'll still have problems

if you dont care about the sound get a 007p on there..

Think thats definately the problem you are having!
