[W211 E220] Airmatic suspension is failing on nearside front and back. Front tyre also very flat despite tyre air pressure being correct.

The car has been to the garage and checked over but they couldn't find any leaks. I'm going to do some troubleshooting but I was hoping for some pointers along the way from you kind guys.

The rear suspension lifts, stops, lifts a bit more, drops, lifts and eventually settles quite low. (I have a video but need to shorten it in order to upload it to imgur)

Get some soapy water in a spray bottle and go wild - any bubbles will highlight a leak

I've just added two pictures which I stupidly forgot and will sort video out. I just wanted to get this post out as I'm super busy and don't have much time.
