wastegate control unit next to coil
Posted by Paul Willis [Email] (more from Paul Willis) on Sat, 29 Feb 2020 15:13:06
Hi. On my 91 turbo on the radiator support right next to the coil is a little round unit with two leads going into the top and three small hoses going to it. I think this is the wastegate controller as part of the APC system. I noticed that center hose had come off as the nipple broke. I am not sure how long it has been that way. Maybe for a while. I get good boost (have the Hot box). That little hose seems to go to the intake plumbing so must send a pressure signal.
1. What if it is off--What will that do? 2. What is that control unit called if I need to replace it?
