Default Problems calibrating air suspension

Hello!

I really need some advice here.

I recently replaced my left front air strut with a used one. After replacing I initiated calibration/leveling of the air suspension. But it seems like it never actually finish the process, so I now have an error message on my dash saying Air Suspension Fault. The calibration just goes in a loop. The compressor runs for approximately 20 seconds then stops for 10, and so it keeps going. The new struts seems to work fine.

The car is a 2003 x350.

What seems to be the problem here?

I have an Ancel with features for the x350. I ordered an SDD cable the other day just in case I might be the tool. So will try that as soon as it arrives

I can confirm that the SDD did the trick. Seems like my tool did not have the function for manually inputting the hight for each corner, but the SDD had.
