Hi guys,
Hope you don’t mind me posting this here, the tt section seems dry..
Recently bought a tt 225 and I’m struggling with a few boost problems.
First off when I first got it there was a definite leak.
Found plenty of splits in the pvc system which has now been simplified.
I’ve replaced the DV and N75 as I was experiencing a surge of boost to 19-20psi then slowly dropping to 12.
I’ve just replaced the n75 and it now stays at 10 psi.
I’m hoping to mock up a bung to pressurize the system and find anymore leaks. I’ve tested from the charge pipe to the inlet manifold and that is sound.
Really stuck for ideas, ideally next move would be vagcom? New to it but I’ll give it ago.
TIA
Tom.
