N75 fault? VAGCOM experts welcomed!

[sion_kwl]

Yeah I changed the n75 coz logs were showing overboost. Immediately after I changed it there was no immediate result but the issue has gone away now I've cleaned the VAC pipes. ALL of my intake, boost, vac and breather pipes were full of oil. Have traced this to the PCV valve, or lack thereof. Previous owner has deleted it BUT no catch can, just recircs straight into the intake. Lots of oil in that area, reckon the old n75 got gunked up that way.

Quick advice do not start change anything.... Go down to the motorway give to 5 minutes in 3rd in high rev (red) and all your proble will solved.

Yes that's really good advice mate stick it in 3rd gear and red line it for 5 min on the motorway lol

did that, was solving issues for a while but as soon as I did any eco driving or dawdling around town etc it came back.

vac pipes, crank breather pipes, intercooler, all had puddles of oil in.
as soon as I cleaned all my vac pipes out connected to the N75 the problem went away. I've currently re-routed the crank breather into a temporary catch can and will be looking for a proper catch can shortly once I've resolved my new issue...

Yes catch can is the way to do it like most of us but not putting stress on the car doing what you said. That's just silly. Yes they do that when mapping a car but that's in 5th gear and not held for 5 min

when I say did that, I wasn't redlining it down the motorway, i was giving it a blast through the gears... I'm not a moron lol.

 

[Sami1219]

Not even me. Thats why i said 3rd maximum 80-85mph and it needs about two mins

Next time write properly then lol
