I have a 2006 LT35 2.5 diesel, would like to replace the N75 valve but there are two valves side be side
that appear to be the same. Can somebody please tell me why? do they do different functions?
thank you

Well where do I start. First of all, got a stage 1 code from Gavin Custom Code a few months ago. Car pulls well enough when the boost works.

So this morning (months after the ECU flash) I quickly installed a boost gauge. Started the car from cold, warmed it up to find that it boosts to...

anyone in Syd have a spare N75 I could borrow just while I do some logs?

Hi guys, I need a help, I bought 2006 polo gti and it runs Giac KO4 tune with 380 infectors on a 3 bar FPR. I drove it for couple of weeks and everything was ok until I took it for a dyno run last weekend and it only made 100kw at wheels. I drove it back home and I didn't have any boost. I have checked...

Hey guys,

I have done a lot of reading, as well as assuming, as well as listening to people perspectives on increasing the boost level on a modified though NOT chipped AGU 1.8t. It breathes much better than stock, and has a 3inch turbo back.

I understand that the n75 is basically...

Hey guys,

I've been searching the webs and have been getting some pretty conflicting reports on using a Manual Boost Controller to up the boost. I'm not looking to go retarded, just give myself an extra 4Psi. I'm punching 10Psi at the moment, and I think 14Psi would be pretty safe. I've...

Hi internet car friends,

I have a 2008 GT Sport TSI. Recently it has been exhibiting symptoms of N249 failure. Replaced the N75, but that didn't fix it so I sent it in for a checkup and the mechanic confirmed from the fault code that it is indeed an N249 failure.

He seems...

Hi,

I just thought I would put this out to the masses to see if anyone else has experienced a similar problem. Btw credit is to be given to Gavin who has been working through this problem with me as much as he can.

Questions:
- Does an N75 fail gradually? Or is it a part...

I'm having a bit of and issue with my 2000 gti. If the car is in 1st or 2nd in low revs (1500-2000rpm) and I press hard on the throttle the turbo goes nuts and I get a rush of boost untill about 3000rpm when it all settles down to regular boost levels. I'm pretty sure it's not going into limp mode as...
