Troubleshooting some boost fluctuation
by Matt on Oct.17, 2009, under Logs, Repairs
I bought a MBC and a used N75 valve to try and correct my fluctuating boost. I don’t install the MBC but I do install the N75. The N75 doesn’t seem to help and after the install I have a “Signal too low” code for my MAF. Swapping the MAF with another doesn’t resolve the issue, it appears one of the wires in the harness may be broken. Dammit.

I am a B5 S4 owner that operates under the delusion that a single car can be comfortable, attractive, and fast. Join me as I journal the repairs, maintenance and mods of my S4 in the attempt to realize a possibly unobtainable goal.
