Worth trying upstream fixes first as omar referred to earlier - plug change, coil change (or at least resistance verify), Techron Concentrate Plus or BG 44K, even Cataclean. MAY clear up on its own may not. If the problem originated upstream, which is very likely, then the new cat will go down the same road. Pulling the plugs will at least tell you whether this approach has value.

A member of the MACT FORD EDGE group has installed the Magnaflow 16871 on his 2011 AWD, it fits fine. Audio clip

Make the call and give the guv the boot!

Need to get a visual on the PTU. I believe if it gets too hot, the car will revert to FWD. Same with the RDU.

Have been told the Magnaflow listed for the FWD does fit the AWD as well. It is tight, but it fits.

AWD always brings PTU to mind. I would check level and condition of the fluid via the fill plug. Would not be surprised if it is sludgy and well below the fill line. If you try a WOT launch from a stop, how does it behave? Does it feel like something is going to break? Or that the wheel is hopping? Then the PTU is done for.

In the absence of oil leaks, if the oil level is good, condition is good, I would not worry about it. I did not hear anything out of the ordinary for an Ecoboost engine. Maybe need to listen to it again ...

Welcome!

Sometimes when replacing the booster, the seal between the master cylinder and booster can be damaged. If that happens, fluid will leak into the booster over time and destroy the booster. So definitely have it checked as low as possible. Another possibility is that air was introduced into the ABS system. That needs special procedures to bleed, normally a shop with access to IDS/high level scan tool can do this. Forscan can now do this as well, so if you can get access to a Windows-based device to load it on, worth a shot.

hopefully the oil pressure switch is the leaky part. coolant hoses? https://parts.levittownfordparts.com/auto-parts/2011/ford/edge/sel-trim/3-5l-v6-gas-engine/cooling-system-cat/cooling-system-scat 2 AT4Z-8260-A Upper Hose EDGE $76.71 $48.52 3 AT4Z-8286-A Lower Hose EDGE $55.82 $35.31

Only in 2015-18 Sports, and probably 2019+ ST as well. But no drain plug and no temp sensor on 2007-14

Welcome! Sad to see the SHO go, but glad to see you are now in an ST! Congrats and rack up those miles of smiles!

Not unless it causes a demonstrable problem with warrantied items. Consumer Protection Act. Anyhoo, one of the reasons to stick with reputable and experienced tuners.
