N75 Testing?

[Y83OLK]

Hi ASN.

Just a quicky, I have been having a few boost issues recently... and seems im just chasing my tail.
I have no boost leaks (multiple smoke tests have confirmed.)
Whats it worth logging via vcds?.
[003,020,115 + 002,106,118?]

Im using Vagcom 3.11 so not sure if all these blocks are available?

And is there any physical way of testing the N75 valve? (ohms reading?)
or simple power run disconnected to see what it makes on actuator pressure vs. N75 controlled?.

TPS quoted me £73 (trade) today for a new n75..
They also told me my 2001 AMK has 2x n75 valves?. are they confusing one with the n249?.
Surely this isnt right.

If you run unplugged, it will only tell you that the actuator is working at the correct psi. It's only when a voltage is applied to the n75 that it diverts boost and thus controls the waste gate.

Have you checked it's plumbed in correctly?

Calllum I've got the latest VCDS loaded on laptop and a genuine VAG-COM cable if you need it buddy.
