You realize you've changed the variables. You've added jobs and parts.
Originally you said replacing an EGR valve was a complicated $800 job. It isn't.
In my opinion, it's one of the easier jobs a DIYer might try to do for the cost of parts. But EVEN IF you paid a competent mechanic to do it, they're not going to charge you 5 hours of labor. Here is a more realistic estimate for that job in your zip code:
https://www.yourmechanic.com/services/exhaust-gas-recirculation-egr-valve-replacement
$379.61 includes
$100.99 labor (not 5 hours),
$256.20 parts (while you can get it cheaper, that's a bit
more than buying a Motorcraft EGR valve at a parts store)
22.42 tax.
For comparison on a 4.0L (my truck), the estimate shows this in your zip code:
https://www.yourmechanic.com/services/exhaust-gas-recirculation-egr-valve-replacement
$273.70 That includes
$100.99 labor (ridiculous I did it in 5 minutes),
$158.81 (I can get a Motorcraft EGR valve for $87 at O'Reilly's), and
$13.90 tax.
I'd encourage anyone with a modest amount of mechanical skills or motivation to do it themselves. I stand by my statement; regardless of the book hours, a
competent mechanic can replace an EGR valve on a 4.6L in under 30 minutes. For 4,0L, 5 minutes. Neither jobs are complicated or expensive.
With that said, I think $379.61 is a lot closer to a fair estimate than $800.00, which is what you originally posted.
I don't know what rate Ford dealerships charge, but I know they will charge on the high side for labor because it's a dealership and some of these dealerships are absolutely beautiful.
Replacing the downpipe is easier, but it probably requires some heat and muscle to get it off. The biggest PIA on getting the EGR valve off on 4.6L is getting the (2)10mm bolts off that hold it on. Mainly because of their location and rear-facing orientation.
As to the other jobs you've listed, I can't imagine why your tech would have to replace the bracket or pigtail connector. Did he break it?
This isn't a contest. I'm a fairly competent wrench, and I'm talking from actual personal experience.
PS: IF you can't or don't want to do your own work, I suggest finding a competent and honest independent mechanic. Dealerships are good for recalls, warranty work, and perhaps electrical diagnostics. Otherwise, I would not use them; you are paying for beautiful dealerships.
