Exclamation Air Suspension - Need Help !!!

Hello everyone.
I met a big problem of my 2009 GL320 Bluetec.
My right rear air bag was broken. So I just replaced a new one - bought from ebay (in pair, but I only use one) and same shape, same model number...
I did all jobs as following the video on Youtube - took fuse away, changed air tube fitting, took away the sensor, changed air spring and then put everything back.
BUT, after that, BOTH rear bags do not work... always stay at lowest position. Front bags work well, pump works well... The message shows malfunction...
(before I did this job, the left rear one works well, only the right bag leaks air.)
I went to a workshop yesterday. They use software to test the suspension system. During the test, the right rear bag (brand new one) lift high to 10 in. But "they told me", the system shows my right rear spring has no response...other three are all OK....
I went back home and took down the new bag, put the old, broken one back....
BUT, still same result - both rear bags stay at lowest position, two front ones work very well....
Please help me. I almost cry last night....how can I do.....

Hi, was there any solution to this? I did exactly what you did and my rear air springs are low. No error on Display. The ride is very bouncy. Is the a calibration procedure I can invoke? I was very careful with the leveling sensor.

Please help!

Thx,
