Suspension help please

[Madwelshman]

I have all round air suspension, and fitted a replacement head and seal on the pump the other day, now getting over 15 bar pressure.
The problem is the back end is low front end looks high and the system will not 0ut air in the back or operate on the raise lower controls.

Does anyone have any ideas as to the problem, no faults showing on the display so I am wondering if the EHC2 module is faulty or should I be looking elsewhere.

Need my car to get to work over 30 miles so can’t use a taxi, getting to the point of having to buy a runaround if I can’t sort it.

Any help would be appreciated

Thanks
