Wastegate actuator/solenoid

[rgsheehan]

Hello all,

2020 Edge 2.0 Ecoboost SEL AWD

 

While passing some trucks on the freeway, on boost, the wrench light comes on.  Stop for coffee, start back up and the wrench is gone, but the CEL is on.  Back to the freeway, power way down, cruise control doesn't work.  Finish my trip, go home and Forscan (using that to try and figure out the low speed surging issue, unsuccessfully so far) shows two codes:

 

P0243 Supercharger Wastegate Actuator 'A' Status (-68)

P0299 Turbo/Supercharger 'A' Underboost Condition   Status (EB)

 

In to the dealer, who said the problem was the 'wastegate solenoid'.  It would be covered under the powertrain warranty.  There was a two week wait for the part to come in.  I asked if I could have the part after they installed the new one and was told 'No, we have to send the part back to Ford', but you can look at it in the parts department after the repair.

 

While waiting, I tried to look up the part just to see what it looks like, how much an aftermarket part would have cost, etc.  Everything I found showed a part that looks a lot like one of the hundreds of other sensors on this engine, with some vacuum hoses sticking out and an electrical connection.

 

Okay, two weeks later I bring the car in, get a loaner, come back later that day, and ask to see the broken part.  The lazy POS behind the parts counter started giving me a bunch of BS about having no way to find it, needed a number, blah blah.  Another guy, sitting two chairs away, said he would handle it.  In 60 seconds, he looked at the computer, got up and went straight to the shelves, and came back with a box and some parts:

 

That, along with the arm that connects it to the wastegate and some nuts and/or bolts.

At first I did not believe that was the part from my car, which led me to wonder whether they did anything at all, and just cleared out the codes in the PCM.

But I climbed under the car and sure enough, I could (just barely) see a new version of that part on my engine.

 

It appears my engine has parts from the 2021+ Lincoln Nautilus:

 

 

Okay, whatever.  So my car (original window sticker mentions a twin-scroll turbo) has a motor controlled wastegate rather that the vacuum operated one.

The build date on my car is December 2020 (yeah I know, Covid car) and it was built on the same line as the Nautilus, so maybe it makes some sense it has some 2021 Lincoln parts on it.

 

But now I'm left with more unanswered questions:

 

Does the PCM in my Edge -know- it is controlling parts from a Nautilus?

Is there special software for one or the other?

Are the folks at Ford dealer service dept. up to the task of keeping track of all this?

Could the mixup be causing the surging and/or schizo shifting issues?

 

The only thing I know for sure is, if you have a modern car and don't have an extended warranty (a good one if there is such a thing), you are so screwed.

Don't know the answer to your questions, but is the car fixed now?  All the issues cleared?
