I did a search on the 06F 906 283 F N75 Valve as Im going to replace mine as some 'process of elimination fault finding',
Is it possible to fit the OEM N75 if I have the Forge DV fitted, I read on here Forge possibly modify the N75?
I can collect one from the dealer in the morning, would I need anything else?
Thanks in advance chaps

This is the thread that confuses me...

Collecting an N75 in the morning regardless just want to hit the ground running

I cant see how having the Forge DV would cause you any problems fitting a N75 valve?

Did you check out the link I found from my search? :happy2:
-
I flicked through it BUT at the end of the day, if you replace a part that is like for like how can there be a problem.
The thread in your link looks to me as if he has got the wrong part number..
-
Will ring Forge before my trip to VW to double check exactly which OEM part is used when installing the DV
-
I run the Forge DV with standard N75 valve :happy2:
-

Yes there are no contraindications to doing so.
I read on here Forge possibly modify the N75?
No they don't! The only way the N75 duty cycle is affected by a dv is if it's faulty or sticking open.
-
Looking at that thread I would be confused how the DV is linked to the N75, looks like one is on the turbo directly and the other especially on your car is miles away round the front of the engine bay. you should be able to monitor N75 duty cycle Mike, think it was dealt with and a funn flutter on boost in another thread recently.
-
i run a forge diverter valve with a standard n75 but instead of buying a new one i am thinking on changing to a forge manual boost controller and see how that works + they are pretty cheap, dunno if it will work but for 40 quid ill try it haha
-
So I hit the problem I was asking about...

I got the part no 06F 906 283F from my Seat parts contact in the Uk. Collected it from parts counter local to me this morning.
The N75 on my car has had the P/n ground off, you can just see the edge of the P from pierburg left. It makes me think the groove At the bottom right of the plug has been ground off by forge too. The new OEM won't fit in the plug on the car as it doesnt have the cut out. FFS :fighting: :fighting:
-
time to get the file out mike! that is so odd that you have to modify the N75 as well makes me think the forge is less than optimal, think they are based in gloucester do you want me to drop by and ask them what the feck they are doing! :confused: :wink:

I would say yes but they're closed lol.
Phoned Awesome where I bought the Forge;
The n75 next to my forge that I just tried replacing is from a tdi, apparently theres another N75 near the brake reservoir...
-
When I did a google search yesterday all that came up where on the turbo. So have they essentially told you your part is fine it will fit on the rear. maybe forge are using a TDI part for some sort of pressure sensor so the ECU knows what the forge DV is doing? i.e if it is open or closed?

I think it's to do with it being vacuum operated not electronically?
The N75 near the turbo too much of a ball ache to change on the driveway?
-
maybe go out for a drive and see if you can log the N75 duty cycle and the DV duty cycle along with the boost pressure and mass air flow and see what results you get might help you to know if you need to bothere changing it?
have you got your original DV to hand? just wondering if its worth re-fitting after logging to do a comparison run?

Original DV is the old diaphragm type & in the Uk, Doh. I would log & / or nip back to dealer and see if they'll fit it but I'm meant to be taking shelves down ready for moving out :sad1:

After lookin at this http://www.etuners.gr/eg/index.php?s=12&t=220 (http://www.etuners.gr/eg/index.php?s=12&t=220) (halfway down page)
I won't be able to do it outside the house.
Do I risk putting SWMBO in a bad mood and goin to see I Can get it fitted lol...
-
Be prepared to get annoyed if you do, they have those special clips on, which might need special tools, replacement ones...
-
I wouldn't be surprised if the dealer didn't have them ring clips in stock, they don't seem to hold anything :fighting:
I'm not attempting it on the drive looking at them clips (& the weather)
-
Will have it fitted Mon with smoke test. Waiting for rain to stop so I can pull MAF out.
Replace N75, 90 silicone inlet elbow, MAF check, smoke test this week.
Got REVO & BF decat DP to go on... Need her running right 1st though!
-
Would you like me to have a check of the p/n of my N75 tomorrow, Mike?

Thanks for the offer. Think I've cleared it up. The forge DV uses a tdi valve and I still have the OEM N75 by the turbo with the pn I originally posted.
Going to fit the new N75 as it's in for diagnostics anyway.

No worries matey :smiley:
Just actualy realised that the N75 actualy comes as part of the Forge DV, it was that long ago since I fitted it :ashamed:

You'll find if you unplug the n75 in your pic it will have the groove like the one I posted, Forge apparently use a tdi valve with the DV to allow it to work properly (vacuum operated?)
I will have another valve near the turbo (I'm ko4) that's the one I'll repose seeing as I have a new one sat here now :)
-
Did you find out a way to get that N75 valve without the groove to fit? I'm running into that problem. No groove, but I got a Forge DV on my MK5 GTI. In dire need cause I think it's whats causing the problem on my car. Thinking of just trying to manually carve a groove.
-
Im sorry it was so long ago, I'll re-read my thread and see if it refreshes my memory.
I'm back on OEM Revision G diverter now.
-
Would be awesome man! I'm thinking of just trimming the edge of the plastic myself. There shouldn't be a big difference between n75 valves. I'm sure the one they use is stock besides the groove.

There was one on ebay for £50 brand new delivered with everything two weeks ago.
