Hey there,
i'm from Germany and new to this forum.
I own a e55 and have a Problem with the airmatic.


Star Diagnosis gives me the following error code (only this one):
5191 power supply valves short circuit to ground


Steps i tried to solve the Problem:
- New Airmatic relais
- Swapped the pressure drain valve at the compressor
- Looked at the wiring and cant see any anomalies


Also the 15a airmatic fuse in the Dashboard breaks all the time and the airmatic control Buttons stop working, until i put a new fuse in. But unfortunately the fuse breaks again after driving some minutes. I think there should be some kind of short circuit somewhere...


Maybe someone knows this issue and could lead me in the right direction, what i should check next?


thanks alot

Thanks for your reply
No i didnt, because i dont own a sd myself and got the error code from the Workshop which got an original sd in house. The Workshop couldnt find the issue yet, so im investigating the problem myself at the moment.

Did you check the fuse under the floor mat? And what exactly is the car doing?

The compressor works if i put in a new fuse in the Dashboard. So there is no need to check the big 40a fuse under the floor mat.
If a new fuse is in, im getting the error message in my Cluster (airmatic visit Workshop). But everything seems to work and i can lift the car up an everything. After driving some minutes, the airmatic fuse in the Dashboard blows and the airmatic control Buttons stop working and the airmatic gets hard.
I got the advice to check all the 4 vales and Connections located at every airmatic strut.
