Going to replace the #6 coil with OEM. Also replace the air box seal as well as the missing wire retaining clip for the airbox.
I promised 20 minutes but we'll see.
I do have a broader work plan so let my organize my thoughts:
- Check generic OBD2 codes. Looking for maybe a history code for coil ...

Re: 14 E63S: forged wheel search
Unfortunately the dealer says the wheels are just no longer available. Here I was dragging my feet due to the cost but I can't even buy them from the dealer. Damn. So now I will be forced to act on an eBay ad for used wheels and then deal with any refurbishment they may require. This sucks.

Re: W221 S550 hunt
It's not clear if there is a single P/N to order the entire mirror assembly. My experience is EPC is difficult with that but the online parts catalog that they have at the dealer now will often show a new P/N that orders the entire thing, so I could call and ask. Or ask when I pick up the M272 ...

Re: 2017 GLS550 Turbo A Underboost CEL
There's a blank spot on the radiator support plastic cover that I think is where the label was supposed to be. There's no sticker there now.
Those can be ordered. In my case it was $16.
Here you go.

Re: 2017 GLS550 Turbo A Underboost CEL
How does it drive, specifically under boost and transitioning in and out of boost?

There was a place in EPC to view the labels.

Wasn't there a sticker under the hood somewhere for refrigerant capacity? I'd also double check that it's r134a....

Re: 2017 GLS550 Turbo A Underboost CEL
A lot of suspension bolts want to be very tight. In fact so tight that the alignment guy didn't tighten them on my E63 enough at my local shop (before I went to the dealer) and I had to tighten them myself because the lower control arm was moving under load and making an unsettling clunk. Then there ...

Usually non-steel bolts are one-time use (in the Mercedes world). There wasn't a note in WIS?

Re: W221 S550 hunt
The only current code is for the dead pass door mirror heater, which has been like this the entire time I've had the car. I should pop some new glass in there and hopefully solve that.
The power folding also gets stuck sometimes and got stuck today worse than it ever has. Had to drive around at ...
