vendt 1 Report post Posted November 30, 2012 What a lazy mechanic.Ha's a very good mechanic,he just said there's no point spending $$$$ on a part you don't need, ask your mechanic if the part is needed if he say's yes then maybe you should change mechanics Quote Share this post Link to post Share on other sites

NZ BMW 368 Report post Posted December 1, 2012 No it won't, it's simply an air pump for emissions. I'm aware of that... the reason I asked is that the CEL is designed to monitor the emissions system, or rather the systems of the car that keep it running with the lowest possible emissions. At least that's what my manual leads me to believe. I just find it strange that they wouldn't connect this pump to the system which monitors everything, perhaps because it was not market specific.

Greg111 13 Report post Posted December 1, 2012 It seems it bypasses all that, it pumps air into the system to burn off all the excess gas, the 02 sensors are constantly reading and adjusting. Quote Share this post Link to post Share on other sites
