Do you, or anyone have ford part #s of the valves, or hell the whole exhaust? (im away from the vehile for a while)At some point, some of you may see a message on the dash that looks something like this...
The dreaded "exhaust mode selection not available" message isn't new as GT350 owners get hit with it every now and then too. There are a number of reasons why the message can come up from melted harnesses, blown fuses, sticking butterfly valves, failed actuators, etc. Since I've spent a lot of time getting to know this exhaust system I figured I'd share what I've seen to date with this system.
I originally added a Lethal Performance resonator delete to my car not long after receiving it. It is a cut and clamp affair and while I was very happy with the sound I wanted to pull the section from the x-pipe back and tig weld it back up. Once reinstalled I wanted to tweak the mufflers so that the quad tips were more in line horizontally. You can tweak here and there a small amount. I wanted more freedom so I cut the mufflers at the fore end, aligned them to my satisfaction, and tack welded everything so I could pull the system again and weld it back up on the ground.
Pulling the system isn't that complicated, it just takes a little time. I removed the rear undertray, disconnected the actuator harnesses, loosened the exhaust clamps/hangers, lowered the system down, and got to work. I just figured this would also be an opportunity to show what you don't normally see regarding the actuators and their butterfly valves below. So with the system out this is what you see...
The actuators are perched up above the tips just aft of the mufflers. They are difficult to access from underneath the car. The shaft and plate (or butterfly valve) that they rotate when called upon resides beneath them.
So if you are this week's winner of the "exhaust mode selection not available" message you can either look yourself and/or drop the car off at your dealer for repair and enter the "that fucking dent wasn't there when I dropped the car off" contest.
I put this quick video together to help illustrate.
The above video should put the next few photos into context.
I'm not 100% sure this gets lubricant where I want but it shows that you could get something to the upper shaft "area" without pulling the actuator off...
I reassembled after cleaning/lubricating and reinstalled the system. It gets easier each time you do it.
Most importantly, inspect your harnesses in the area of the valves, ensuring they are not in contact with the mufflers or the tips as they exit the mufflers. Some have had issues with melted harness and blown fuses. When this happens you'll likely get a message regarding mode issues. One of my harnesses was sitting on the exhaust system as it's pushpin to hold it up and away was never put into place. I rerouted it giving it more clearance and zip tied it.
You can also have a valve that simply froze up or an actuator that died. But you should be in a better position now to try to identify for yourself what may happened.
Im having my whole exhaust changed out under warranty due to the valves
well that sucks.. But ive got 4k miles and constant changing, and never had a valve issue. iether its a QC issue, or i feel my car was really paid attentionto for some reason - an early build, through process fast, and 0 production issues.
Have you been open tracking the car?
I tracked the car once at sebring the valve issues have been ongoing since I took delivery It is under warranty and actually ford is working hard to figure the problem out since its not a one off problem not sure if heat would be an issue since the valve motor is above the exhaust and the motor is not burnt up the issue is in programming each movement is a permissive to tell the brain which mode is selected if there just a slight over travel or it gets slightly stuck due to carbon buildup u get exhaust valve not active on the dash and it blows a fuse due to the over travel or no travel from the valves
