F15 X5 2017 Aftermarket air suspension

Under hot weather conditions, the rear air bags failed to inflate and the compressor even came to a halt, likely as a result of thermal cut-out. Once again began working approximately one hour later.
Finally decided to replace the rear air bags, compressor, and relay because the car is 8 years old and has 50,000 miles. Got a price of £1400 for these parts alone when I called a local supplier. When I asked about the price, they immediately brought up the BMW stock prices. I called BMW to get a quote for the entire job, and they said it would cost £3500 for three hours of labour. Holy cow!
I opted to handle the task on my own. Purchased OEM components on eBay for a total of £217. I was able to complete the DIY job in just 5 hours after receiving parts that were visually identical to the ones on the car. The parts arrived after 2 days and the instructions were very detailed, thanks to Google AI and YouTube. I was surprised by how easy it was. Just one thing to keep in mind - the instructions state to "Inflate new air bags with the car jacked and wheels just touching the ground." That's all. No coding required. This is incorrect because the compressor cannot be activated by the ride height sensors unless the car is lowered below its normal ride height.
Contrary to what Google suggests, neither the air bags nor the compressor have "Push fit" connections for airlines.
My sincere wish is that this data will allow other people to cut costs just like mine.
I should mention that the original compressor was actually manufactured in India and was not even badged as BMW.

Lol, AI is deceitful.
You must have installed the new "O" rings to prevent leakage.

In addition to the valve block and fittings, the new pump I purchased also came with "O" rings. For air spring bags, a "O" ring is not necessary. AI also mentioned that the black pipe connecting the compressor to the valve block had a 10 ml nut that, when unscrewed, would release pressure. Yet again, I am mistaken. In order to proceed, either use software deflation or release the red and blue lines.

It has been a long time since I last did mine, but I'm still confused because I thought the pipe to bag had an O-ring.

Even though I'm 81 years old, I won't be sleeping tonight because there are no leaks and the ride is much better.

So that I can adjust the ride height, I just bought a Launch diagnostic tool.
