airmatic code 5507

[Jack1255]

Hey all,

C219 with airmatic, front left strut just changed due to split and caused red car too low message. Strut changed over but now after a min or two white message saying airmatic visit workshop.

Have scanned and cleared all airmatic faults but code 5507 - “suspension strut is unreasonable”

have unplugged and reconnected both connections to the strut, height sensor works as pump kicks in when raised / lowered by jack.

Does 5507 mean the strut is defective?

Have got a new compressor but is that code related to the pump or not?

Thanks in advance for any ideas

Well the relay may need taking out and changing or just give it a tap.

Was the strut an mb unit or a pattern part.

Thanks, I’ll give it a go today.

It was a brand new Arnott.

The new strut is raising and lowering but it’s not reaching the correct height, when pressing the raise button you can get it up higher but after 30secs of compressor running the white visit workshop appears.

I took the relay out and tapped it a few times, still same issue - have ordered a new one though just to rule it out.

Had another scan and I get the following info
How does it all look?

Voltages - 244, terminal 30 14V
091 - terminal 87 - ON

level sensors
Left 040 B22/8 - 2.49V
Left 041 B22/8 - 2.49V

front right is 2.63V
Rear is 2.53V

vehicle level
042 left = -9mm
045 right = 5mm
048 rear = 4mm

acceleration sensors
030 B24/3 (left) 2509.80mV
031 B24/4 (right) 2490.20mV

AIRmatic pressure
049 B7 = 17.16 bar


Is the left sensor in the tolerance range at 2.49V?

Am going to get the front up again so I can check the wiring connectors.

Thanks in advance
