Trying to help my daughter with her car. Multiple codes, reduced power and very sluggish acceleration up until 40mph. No check engine light. List of codes:   ABS Antilock braking system : DTC Description Status U0140:00:20 Lost Communication With Body Control Module CMDTC U0265:00:20 Lost Communication with Image Processing Sensor A CMDTC U2107:00:68 Collision Mitigation By Braking CMDTC U3003:16:60 Battery Voltage CMDTC   PCM Powertrain Control Module: DTC U0284:00:68 Description Lost Communication with Active Grille Air Shutter Module 'A' CMDTC  

They add a slice of light way down low that doesn't illuminate up high, they are effective fog lights.   If you are going to keep the LEDs, you need to clock them correctly (turn them if they have that adjustment) to get the best light out of them. It helps to know how the projector fog light works.   There is a slot the light goes across between the bulb and the lens: The projector lens actually flips the light (so any changes made to the slot or gate will affect it opposite, add a hot spot on bottom will add it to the top of the projected beam).   Most of these I saw in the junk yard (when working on a project, that I abandoned as it was counter productive) were pitted (with them being low to the ground and not protected behind a lens like the headlight).   The pitting on mine (mocking up some LED rings, which were actually brighter than the fogs, so I didn't finish it) is not quite as bad: Just the LED ring in, this is why I didn't go forward with it (you can see the halo in an artifact way up high): With fog light on, compare no halo with halo. This is what a non focused non projected light would look like, not a good fog light at all: What that non shaped (by fluted lens, projector beam, capped and reflector, etc) low power LED looks like:

Exactly what I use mine for as well.   They call them " fog lights " but in reality they only make things worse.  Adding more light, or certainly driving with high beams on in the fog scatters so much light you might as well just shut your eyes and hope for the best.   The term " fog lights " is a misnomer that has stuck around for far too long.

I guess it depends on what your expectations are. They are really only obviously on if your headlights are also on as a small strip down low and to the sides. They aren't driving lights, they don't throw, they don't add light up high, just low to the ground and close. I found that H11 LEDs made them worse. I don't actually drive in fog, but use them to illuminate the ground close to the car when going slow. They also help illuminate animal eyes that headlights might not.   My 2012 Fusion has the exact same fog lights. They are sorta pitted but maybe not that bad. They are available on the aftermarket for $25-50 each.   This a day shot on a wall:     fog lights only:  

My actual fog lights seem very pitted.  I added LED bulbs, but they are still very dim, or maybe I should say they don't throw light very well. If I just turn the fog lights on at night in the driveway you cant even tell they are on. I tried polishing the lenses, but it didn't help.  Is this just normal or should I just buy some new fog lights? The actual fog light itself, not the bulbs.  Its an 08 Edge.

And got a slightly smaller Ford emblem.  The non ST and ST line Edges got a 9” Ford emblem where the ST and ST lines got the 7.75” emblem.  I can’t help but stare at it more when I glance at it.  I park it at work and walk away and turn back and glance at it.  Guilty, I know…

Valve body came in yesterday and I dropped the car off this morning on the way home from work.  Back in another Bronco Sport.  Service advisor said he would call me tomorrow.  Wait and see…

Yep, they are doing their due diligence and they aren’t doing me wrong at all.  It is a shame the Ford dealership two miles from my house couldn’t do better.  Another story for another thread.

I thought I noticed it the day I picked it up, but I put about 400 miles on it and had a friend confirm I wasn’t hearing things before I called the dealership.  So it was within the week I picked it up that I was calling them back and telling them it was making the noise and jolt again.  I don’t know how good their dedicated transmission and engine guys are, but they are taking care of the car and honoring the warranty so I can’t complain.

I missed that detail - the Ford service shop were unlikely to have noticed the issue if it only manifest itself 500+ miles later.
