Same boat mate, I'm basically getting exactly the same symptoms but my code is 17963 which is an overboost one! Gonna bite the bullet and get it leak tested shortly, I'v had enough of no power!

Guest, New Stock alert: Premium CUPRA valve caps now available in the store ? Order now from the merchandise store
17705 - pressure loss between turbo and throttle valve,
- Thread starter Mk1 banana
- Start date
Spot on fella,mine is exactly the same symptoms,goin to plumb place see how much an end cap is to build a boost leak tester..
Good idea Richie, certainly a lot cheaper than buying a kit!
Mine is gradually gettg better, (jinxed myself now lol!) generally, I've even fiddling with the split r lately, (full recirc anyway) seems to b helping, I occasionally hit limp mode though, it's a little annoying but last time, I managed over 100 miles and she felt like a different car, then as soon as I say 'I think the split r is set up' (on another thread)I hit limp mode (0.3 bar boost) within 10 miles! Arghh!

Could be the variable vanes sticking in the turbo
Wynnes turbo cleaner=£10 worth a go
New turbo £250-700 parts alone (k03s) ouch
Maybe n75? £50 ish
Just an educated guess...

(DIAGNOSED) Here goes, I've jinxed myself already!
I think...
The problem was the recirc valve, I've established that the old unit holds less than 0.4 bar and the new one (holds 0.6-0.8 bar) its a split r
Need i say more to those of you against the splitters! (I agree, slightly)
I spoke to amd and they said its probably just the way the valve is as they have a tendency to leak regardless to how well serviced or set up they are.(even full recirc)
I didn't say I'm chucking it though!
It sounds too good!
I also have a slight leak from the 'pancake hose' so ill be taking the seal out for the 3rd time and making sure Tps get me the right one this time, as we now have oil drippage.

Yes. I know lol. You've been telling me for a while now, I just thought, as a friend has no issues with his, I'll be ok with mine, it'll be less of a problem when it's remapped
(hopefully)
If its that bad, I might just have to listen to you lol standard/ 007/008p
The fault code is Intermittent now, better than consistent, and feels better to drive...
Just out of interest, Where did you get your knowledge from lee? Are you a mechanic/ In the motor trade?

Split-R = Leaky DV
Replace it with something which works and does'nt leak and check your other pipes for leaks also..
smoke test it if you know somewhere local who have this kit (I do)
I want to, get it smoke tested but not sure who will do it locally...
Where are you based?
Any decent garage should have one. TC garage near east grinstead have one and looked after my car well. Try local tuners or vag specialists.
Considering how dependent the engines are on measured air its a no brainer. Certainly worth having it done after any power/pipework changes
Thanks mate, but its a little too far from hastings I'm affraid... How much for a stage one and how much for stage two from you?
4 things:
Check the pressure control valve in the crank breather system
Check the MAF wasn't manufactured in 2001
Go to seat and see if there is a software update for your ECU that will cure any intake air temp related issues
20vt engines don't use VNT turbos
Fault code 17705 was created to test every mechanics metal, I've come across it numerous times and always found the cause which seems to be different every time.
