Are you still looking into this?

@Iroga did you buy an OEM harness and plug as well as the light? I have a light with backing plate on the way, but need to find a plug or wiring diagram for the 3 pins on the light itself. Thanks

Read through most of this thread. I recently acquired a 2019 Edge Titanium that exhibits the same stumble and stutter under feather light acceleration up to about 35 MPH. From what I have read in this thread it seems there are multiple possibilities. I will read through this thread again and see if I can come up with Step 1: unplug DPFE sensor and check driveability, Step 2.... and so on.   I have some other things to discuss with the place I bought it from, but that is another post...   If I drove like i did 30 years ago, I may have never noticed the problem. But under light acceleration, yup, the stumbles and stutters are there.

My advice would be to use a reliable scanner like Forscan as a first step in the diagnostics, and monitor the O2 and fuel trim data.      

I ran codes with my old Actron and my son's Blue Driver; no codes came up! I've had Forscan for a decade, but still haven't figured out how to use it beyond loading the stock info, of my 02 F150 Screw

Welcome.   The smell of rotten eggs comes from the CAT which only happens when un-burnt fuel get into the CAT which is a sign of an ignition or injector issue. If its been going on for a while you may need new CAT's by now but address the fuel issue first or the new CAT's will be toast in a short time.   The fact that its getting in to the cabin is a secondary issue.   Have you used a reliable scanner such as Forscan to check for codes?    

I just bought the '17 MKx 3.7 FWD in May. After a few weeks I noticed when I'm accelerating harder to merge into the Freeway, a few seconds later we smell the rotten egg! I never notice the smell any other time. I read a bunch of TSB's about the issue. beside the Cats, a lot about the vortex (behind hatch) sucking the smell into the interior.  Any ideas, beside new Cats?

Is this one of the models where Ford did away with the aesthetic / acoustic cover?

My 2024 has a similar sounding noise but certainly not near as loud.  I can't hear it inside the car, but pop the hood... and it sounds like a noise that not suppose to be there on a newer car.  I will try to pin point mine with a sethascope and I will be asking the dealer about it too.  I read somewhere the high pressure fuel pump can be noisy like this.   my daughter's 2006 focus has a similar noise and intensity and it almost sounds like the intake valves clattering under the valve cover.  Turns out the intake manifold runner has some wear and it clatters quite loudly.  Seems this was an issue in those early focus's.  Do let us know what you find out on yours.

Found it in BdCYM, plain english, search ramp and changed from disabled to enabled.
