Codes 17544 & 17546 '98 A4 2.8 30v

[Tony Hoffman]

First thing I'd be looking for is vac leak. Easiest way to find it smoke
machine, or thorough physical checkover. If no leaks are obvious, check the
purge valve (though usually this is accompanied with an EVAP code. If
thats' good, possible bad MAF.
