i had this problem mate, if i put foot down from low revs by the time it got to around 4k it would just make a whoosh noise and then feel like driving just a 1.8 with no boost. and then all of a sudden go back to working normal again.

I've got this problem lol goes into limp mode then turn it off back on its ok. My code is that dreaded 17705

I dint get limp mode, car still felt smooth as anything just no boost lol, felt weird. what i did was unplug the n75 and it shud run normal still but there will be no boost, then this was exactly the same to what it was doin when it shudent off been, so i narrowed it down to n75 got a new one and never had the problem since
worth a try tho mate to unplug it and see what happens.

 

[Longy82]

Yeh will do mate and yeh few people said that's limp mode as they do drive perfect just no boost as mines doing that now but will try unplug the n75 and let u no what happens lol

I have the exact same problem it's so annoying lol, I've done the n249 bypass thought it was this but obviously not! Changed plugs, checked most the pipes I can see no boost leaks etc, my DV is sound, so like Ryanb said I'll try the n75 valve

 

[Longy82]

Same here av done the bypass put a 007p dv on replaced vac pipes and still the same so yeh n75 next lol

So I did reply to your thread I didn't even realise it was same person lol... Yeah the n75 valve aren't cheap tho.. Dearlers price is about £75 I think it was when I rang other day.. So ebay it is haha

 

[Longy82]

Haha yeh mate eBay there's some genuine ones for about 50 quid new I was hoping someone close to West Yorkshire would let me try there's first before I bought one lol

Lol it would be handy to see it it was the problem.. You can do a test tho can't you? Suppose to unplug the n75 valve and drive with it unplugged but they'll be no boost and if it doesn't do it then it's deffos the n75 valve lol

 

[Longy82]

I'm not sure mate there's mixed views on it tbh so think best thing is buy one try it see what happens that's what I'm going to and hope for the best lol

Can you not log the duty cycle on vag com? That would show if n75 was opening early... Think this is what mines doing as well as randomly dumping mid way through 1st and second gear

 

[Longy82]

I have no idear how to use it lol I'm going to buy a cable and give it a go

Yeah mate checked loads of pipes took them off and put them back on no splits but have replaced a few pipes tho as they was a bit f**ked lol can only think it been n75 valve na.

 

[Longy82]

No worries just I looked 5 times then thought fook it take them off and one right under the inlet was split but I'm removing the pcv system soon as I'm just on with making a catch can

What is the Pcv? I've seen loads of ppl talk about this and I havnt got a clue what it is lol

 

[Longy82]

positive crankcase ventilation.its all them annoying pipes to the inlet ect so remove with a catch can then your engine will breath better without all the crap going back into it
