Hi

Could someone who's tech certified or experienced in this matter please lend some assistance.

17887 - Brake Boost Vaccum System: Mechanical Failure
P1479 - 008 - Implausible Signal - Intermittent


I'm assuming theres a leak in a vacuum line, how do I go about finding the problem and rectifying it.

Thank you.

 

17887/P1479 possibly your vacuum pump failed, needs to be checked out, or this is what searching the form can get you https://www.audiforums.com/m_364038/tm.htm

 

First clear the code and drive for a couple of hundred miles and see if it comes back. If not, it is an old code that happened some time in the past for some reason.

 

Thank you
