ABC filter and flush gone WRONG! Need Advice

I was attempting a flush on my 2013 r231 with 106K miles and I believe got air in the system while changing the filter and pouring in CHF 11s. The car is in the lowest possible position and it will not pump back up. and is give the ABC Failure/Stop Car error. The fluid level is good but it won't prime any fluid to fill the shock.

I am going to try and raise the car up and get it off its wheels to allow the shocks to expand and see if this helps but any advice would be super helpful. I'm totally bummed and appreciate your time.

Thanks,
Ryan

Or put the pressure in right before you start it. But make sure to not over pressurize the tank with a compressor that gives constant airflow. This only takes about 30 seconds or so and should get you fixed up.
