I figured we need a thread like this just so we can see what others are up to.....
I'll start. My summer tires came in today hope to have them mounted and installed in a week or two or at least before summer ends. Just need to find the time to ceramic coat them and get them mounted and balanced.

Recharged air suspension reservoir/front & rear axles, drive tested and performed static leak-down testing. This is the post-compressor/valve-block swap out validation phase prior to install plastic protective cover/reinstall running board. Also performed the 'leveling' of car where you have to measure the exact distances on each corner from center of wheel to the fender lip and enter it/save the data so car can adjust itself to the correct ride height. This is a required step whenever you swap out the compressor or valve block/controller, BTW, if you want your car to be level anyway.
I learned that if you are replacing your air compressor for air suspension, then you'd best plan on replacing the valve-block for air suspension as well, as no doubt you will mount the compressor up only to find out that now the old valve block is failing since you have to break the old line seals loose to remove the air lines. Yikes! Knew i should've ordered both parts at the same time, but I hedged since the original valve block wasn't leaking, and thought I might be able to reuse it. No such luck. Once you break open the air line compression seals on these old valve-blocks to get the compressor off car, it's hit-or-miss as to whether it will seal back up again.

My new Q7 was very creaky compared to my last one (RIP), especially over rough roads.
I applied this G052141A2 grease to all the seals around the edges of the sunroof glass and it made a huge improvement. If you have a panoramic sunroof I would definitely do this to keep the seals happy and quiet.
Haven't had to touch the fog lights thankfully. My headlights have some oxidation and spots, not too bad though. Once I get a garage, I'm going to clean them with this:
man for a 2007, it looks awesome, even your headlights are not foggy. Any secret? Mine are foggy on 2014.
The UV protection doesn't last forever, and if it's been driven a lot on the highway, then you get micro-abrasions in the surface...kind of like sandblasting, that make it look 'cloudy'. Feel the surface of the lens and compare to a clear portion on top of lens where the hood covers it. Most cleaning kits are just about sanding down the rough surface to a very fine grit of paper, then buffing it with a polisher/UV protector, etc.
Whatever you use to clarify the lenses, it'll be easier if you do it off the car (they are modular and whole assembly slides straight out the front of car). This is a perfect time to swap out old HID bulbs too, since you have to remove the housings from car to swap the bulbs out, and HID bulbs degrade significantly in output over time. Once lenses are clean & clear again, they must be sealed against UV rays, or they will cloud over again in a short time frame. I consider headlight lens clarifying to be a 'Spring cleaning' event on our cars.
Lastly, you can DIY the headlight cleaning yourself, but so many places now offer this service at reasonable pricing; what's your time worth? At Sam's Club and other locales I frequent, I've seen it for $45 and up. Considering the cost of the kit, the time it takes to do it right, avoiding damaging your car's paint finish, etc., etc., I'd suggest to pay for it. The only reason I'd do it myself (as a first-timer...there is a learning curve), is primarily to change out he HID bulbs, then w/housing removed the job is much more straightforward w/o causing damage to the car's finish.

Look what I did to my Q7 today.....
