You have no detonation protection right now Posted by Bernie [Email] (#1501) [Profile/Gallery] (more from Bernie) on Sun, 1 Mar 2020 11:48:24 In Reply to: Re: wastegate control unit next to coil, Paul Willis, Sat, 29 Feb 2020 19:07:55 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Hello,
That solonoid is how the APC system controls boost and thus detonation. So you will want to replace it. The knock sensor sends a signal to the control unit which then controls the APC solonoid to control the boost. It is very likely that the solonoid was faulty before only allowing base boost and now that it is broken you have no boost control. Or you problem could be another component and you will only have base boost after replacement. But you want the APC system to function correctly so you don't melt pistons or worse. Good Luck, Bernie
