n75

[mark_20vt]

my cars currently got a n75j on it and have been told that when runnin a k03 this can cause probs... on vag com i've got 'boost control pressure: negative deviation.' under low boost and when cold the dv wil chatter (chchchch rather thn pchhhh noise!) hope this makes sense to some1 who has encountered similar, so would i be best off gettin a new n75? if so where is cheapest?
cheers peeps

 

[m0rk]

yes - put an original N75 on (C or F)

but the sound you're getting is most likely from a knackered DV

 

[mark_20vt]

wheres best to get a new n75? westec? i've recently serviced the dv (forge 007p) and everything looks spot on including the integrity of all the seals...

When the hose off the top of my DV blew off i got really loud "chatter" check all the hoses are on properly and clamped. i've just read that chatter will screw your turbo??!!!

 

[David_smith_909]

yup, chatter is very very bad for the life of your turbo

if you have serviced the dv and its still doing it (after checking all hoses etc ..) id get it changed mate, sooner the better as well

I have just bought a new N75 F valve to see if it fixes a problem, if it doesnt then it will be up for sale.

By the way they are £50ish from the dealer.

If you were running a KO3s would a n75j be required??? Wot gains??? I thought the valve was for requesting boost so surely this is changed when it gets mapped??

I have had the same sort of fault code but with 'Positive Deviation' although i think it still related to the N75 Valve

Like m0rk says, you need to get a C or F Valve although i would go for an F Valve really

Here is the Part Number (from the MK3 Cupra Part Numbers Sticky Thread) :-

N75 valve: 058906283F (?)

Well i saw on ebay a n75j off a tt225 and he said it can be used on a remapped 150/180bhp 1.8 20vt 's obviously running more boost than std.

Alex,

The part no on the LCR F valve is the same - 058906283F, so the answer is yes.

Thats bizarre!

I made sure i gave them the Part Number! I was quoted £58 including VAT and delivery from two places?

 

[sportbilly]

£58 was what I was quoted, asked for discount when I collected and he knocked off 10%

Really? How did you manage that?

 

[sportbilly]

Just ask, normal trade discount. I use them all the time for servicing so I am sure there not out of pocket - not the way the LCR gets through brakes!

Most garages I have used in the past will give 10% discount if you ask nicely.
