delfinis38 1 Posted February 22, 2011 (edited) what is that buzzing noise ?? It comes from the engine when the ignition is on, no engine running. seems to come from right hand side of the engine (pass side) just under the big round electrical plug that goes into the engine. I've never really noticed it before. is it the ECU buzzing ? Edited February 22, 2011 by delfinis38 Quote Share this post Link to post Share on other sites
