i have a 2k TT Quat 180hp, normally the turbo with spool up around 3k-ish. recently that hasnt been the case, im getting no odd noises so i doubt it is the turbo itself, and no vacuum leaks, but sometimes the car will boost intermittantly and also at much higher rpms. can this be a N75? or is it something else. if anyone might know help would be appreciated. thanks

 

It could be your N75 valve.

 

is this a common fix for boost discrepancies? and where can i find one? a stock one that is. oh and how much $?

 

more than likely its the n75 valve, but doulble check all boost plumbing and the dv.

 

its a new dv, and i havent found any vacuum leaks so that leads me to the n75 i guess, anyone have a price or a place i can buy a stock one?

 

just go to the stealership there 76 bucks ecs has a upgrade for 90. Just curious, have you ran the computer codes?

 

The N75 will throw a CEL, or at least store a code.
VAG the car & see if there are any codes.

Could be...
Bad DV, boost leak, faulty sensor, or N75

 

i havent ran a VAG cause its not throwing me a light. i think ill grab me a new n75 and start from there, just reading through similar problems on a search alot of fingers point to n75.

 

Oh, your going the "just throwing parts at it" route.

Even if the CEL isn't on, there can be stored codes. It can be something as simple as a pinched line on the N75, or a faulty connection.

 

like i said theres no pinched lines or leaks, ive searched through the compartment and found nothing, if i could get my hands on a VAG then i would run it.
