Broken rear spring

Bear with me going the long way around the barn here. Just finished learning the hard way on a family member's BMW X5 with air rear suspension. It's a ridiculously complicated self-leveling system, with air bags, two sensors, a pump and a computer. The old car cheap fix is to remove the air rear suspension and replace it with steel coils. Yes, cheap, but ruined the feel of the Beemer; with the coils it sat too high in the rear and the ride and handling just felt wrong. After it was too late, I realized the cheapest fix, since the air bags were still functional, would have been to remove the sensors, compressor and computer and just run the air lines into a tee with a guage and a Shrader valve on it and manually add air if a heavy load was carried.
Same but different, I've got an extra set of air bags from a pickup truck kit. If I find the rear coils on our '18 Q5 broken, first thing I'm going to do is see if the bags are even close to a possibility.
Do I remember some of the SQ5s have air suspension? If so, anyone have a photo of the rears?

FWIW, I just spoke with an independent shop and it seems GM had the same problem with broken springs. They and probably Audi found a spring manufacturer who promised a smaller, lighter, cheaper spring and that's where we are today.
The second hand info is the NTSB was in the process of forcing a recall on millions of GM cars when the bankruptcy mess hit and GM ducked the damages.

I asked for closer pics on the previous victim and he never posted any. Because his looked like rust to me.
Even a blind man can tell rust is the cause on this one. We went through a few sets of rear springs on our B5 A4 always caused by rust. Haven't had any go bad since then.
Maybe some rust preventative not harmful to the lower mounts would be a good idea going forward.

FWIW, I just swapped winter-to-summer tires and wheels on our 55,000-mile 2018 Q5. While the rear tires were off, I carefully inspected the bottom of the coil springs. No rust, no signs of breakage. So far, so good.

2019 Q7 67k same issue
My 2019 Q7 just went into the dealer for a noise coming from the rear. Spring broke right off and the other side was about to go. The dealership didn’t hesitate to pay for the repair without me asking.
It is a concerning issue though.

Ok, I wasn't correct about the lower spring mounts causing this. I went to check the driver side (it was corroding last year), and when I looked at the passenger side (which was replaced last year), I was greeted by a broken spring. Arrrggggg... super disappointed on the build quality of this car. Apparently we are all still paying for diesel-gate....

If you are replacing the rears, I suspect you would be replacing the fronts as well. I think you have to really. I've replaced my OEM springs with ABT H.A.S kit. You could use the same, even if you don't want lowered ride height. It can be set at or close to the OEM ride height. Handling / feel are dramatically improved.
Outside of that kit (which is a little bit pricey), There are a number of reputable spring kits that would have modest lowering. The OEM ride height is honestly so ridiculously high that lowering an inch will just make it look "right".
If you want a modest improvement from a very reputable and reliable company, this kit would be my recommendation... https://eibach.com/eps-search?pf=PRO...attro+SQ5+3.0L
I had an Eibach Pro Kit on a BMW X5 and it was dramatically better than OEM, but still very much an OEM feel and height.

I bought a 2018 CPO Q5 'early production..Only 20,000 mi on it. Had it for 6 months ,& $4,000 warranty repairs. Traded for a 2020 CPO Q5. Have it 3 yrs and no problems. Strongly recommend the 2020 model. It has many features the 18/19 models lack.. If buying used get a 2020. Audi finally got it right.
