I have searched and searched for the DIY for installing a MBC for a 1.8T. I looked in this forum plus the MKIV Forum searching for both MBC and Manual boost Controller with no luck.
I tried installing one by disconnecting the two hoses that come of the N75 valve and plugging those into the MBC. I capped the N75 ends and left it plugged in. When I do this not matter which way I plugged the hoses in, I could not boost more than 5 lbs of boost.
Is there a write up or any pictures on what to do? I think I have done it correctly and perhaps have a faulty MBC (it is used.)
Any help would be greatly appreciated!
