I just got a new 2008 E61, and the windshield is sandblasted pretty badly. Need a new one ASAP. Meanwhile, I have 9C55 and 9CC5 codes (fogging sensor, and rain/light sensor). Is a blasted windshield enough to cause these codes? When replacing a windshield, is it wise replace the sensors as well, or do they last and transfer easily enough?
If I had to do it all over again, I would replace it to leave out that the part is the issue. After I had my windshield replaced it was probably 6 years after I had it replaced again due to a crack and I got a fogging sensor error about a year later. I diagnosed it for a few days and decided it had to be an electrical issue. It was time to change my 7-year-old battery anyway, so I changed it and it wasn't the issue. I unplugged it cleaned the connector and plugged it back in, cleared the code and it hasn't been back since. A lot of people have issues with those sensors and have a hard time figuring out the issue. You decide what's best for you, but I would as I said. Now would your current state cause the error I highly doubt it. You'd have to barely be able see out of the windshield to make the sensor error.
I like the logic there... That said, I've circled two rock chips in yellow below:
I don't know what sensors are where (still getting my feet under me here), so that may or may not be the sensor associated with the codes being thrown... How do I figure out which sensor(s) I need here?
Your rain sensor looks like it was replaced/remounted before. Your fogging sensor sits towards the bottom of the black outline so you can't see it from outside. Your windshield at its current state would not affect the 2 sensors job. I would physically look at it to see what's going on with it.

What am I looking at exactly?
The 9C55 code says "IHKA (Integrated Automatic Heating and A/C System), fogging sensor", but that's about the extent of what I've been able to figure out so far. It's a noun without a verb. I genuinely don't know what the sensor is supposed to be doing, so not sure if it is or isn't doing what it should.
The 9CC5 code says "Light Module (LM), no message, LIN (RLS)", and that's even less helpful. Digging around shows that it comes up frequently with myriad other unrelated codes, but every time it comes up, it's pretty much never addressed directly. I found one person on some forum or another saying "the dreaded 9CC5", but I don't see any other such references. Finally, I found a few references to it coming up, but never being resolved. I truly don't know what to do about it. The only clue I have is that the two sensors are, I THINK in close proximity, and my windshield (also in the same proximity) is in extremely bad shape. The rain sensing wiper function does work. I don't know if it's working as well as it should, but it works well enough to say it works.
I'm not opposed to the idea of throwing parts at it while they can be thrown. My windshield guy says they usually transfer just fine and don't break, but they're difficult to get off and back on without the proper tools, and there's a risk of breaking the windshield in the process. This seems like one of those instances of get while the getting is good. I'm poking around on realoem.com, and having a hard time figuring out exactly which parts I should be throwing though...
I think the parts are:
64116928326 Set, Condensation sensors, bonded and
61359248398 Substitute visuals, RLS
Both of these are for auto climate but no lane departure.

It's easier to take apart the cover and see which ones you have otherwise you'd have to know the options your windshield and car has. Are you sure you have an 08 and not an 07. I thought the last US market E61 was built in early 2007 and it was a 530xi.
2010 was the last year for E61 in US. 530xi ended in 07 as did the pre-LCI E61s, LCI from 08-10, and 535xi for 08, and I think it was 535i xDrive for 09-10 (not sure if 09 was 535xi, or 535i xDrive). All E61, just different engine and branding for the all wheel drive system. All the name swapping in there made hunting for this car extra fun!
I dug around a bit, and found out how the cover comes off. I'm going to try to get in there tomorrow and see what sensors I have. I know the options, so I'm pretty sure, but I'd rather verify. Assuming I have the correct part numbers, I'll get them ordered tomorrow afternoon/evening.
My fogging sensor in my E61 has always reported an error since I bought it. I recently had my windshield replaced and I hoped they would replace the sensor since according to what I read in TIS, it is single-use and is bonded to the windshield. So I went back to the shop after the replacement since I still had the error and the guy there quickly popped the plastic cover off behind the rear view mirror and showed me that I had a sensor that has a bracket that holds it in place and he said it was never bonded to the windshield (not 100% sure I believe him, but I can't prove otherwise). RealOEM shows that I should have a bonded sensor (64116928326). RealOEM also shows another sensor for the X5 (64119115220) that it says is clipped but it uses the same photo with the mounting tool which I believe is incorrect. If I got one of the bonded sensors I'm not sure how I would get it in place because I would have to slide it under the plastic clip.
My question for you, would you be willing to take a look and see if yours is bonded or not? I'm sorry to say that I don't have a picture of mine. I ask because I'd like to replace mine but it's kind of expensive and I don't want to get the incorrect one.
Here is a video of what the bonded ones should look like:
Well, you’re in luck! I popped the cover off this morning before leaving the house and took those exact photos. Mine appears clipped and not bonded.
There’s a metal bracket bonded to the windshield, and the sensors appear to be clipped into it. Whether they’re bonded in addition to being clipped was not immediately obvious from where I was in the time available, but I was able to confirm my part numbers at least.
Ok the RLS was the one I didnt know which one you had. Your glass type was going to dictate that. From the original windshield pic it looked like the circle one but didnt want to guess at it.
