2007 CLS 550 AMG
2007 CLS 550 air suspension problem, need scanner !
Hello, I have a 2007 CLS 550 AMG that the air suspension has went down. I am wondering, can anyone tell me what scanners are available that can scan all fault codes in this car, not just engine and emissions fault codes ? A generic OBD II scanner if it will scan everything I don't mind spending the bucks for. Or, how about these small model specific blue tooth devices, are any of them any good ?
This problem was first noticed when parking, the air pump continued to run for several minutes after the car was parked and off. Then we would occasionally get the air suspension problem. Now the front appears full down, and, when turning on the key or starting the car, the air pump NEVER runs. I will have the air ride relay tomorrow, I have checked the 40 amp fuse, it's good. Thinking a scanner would be good in case it is a ride height sensor fault or similar electrical electronic problem. Otherwise, if the new relay does not get the pump to run on start up, I would have to begin by replacing the compressor.
Thank you,
John

shopping for 06 cls55
According to this airmatic troubleshooting guide:

You will need an OBD II scanner such as Star Diagnostic or to read the fault codes.

I've had a similar problem. First thing, replace the relay. You can swap relays in the box to check if that's the problem. It's probably the pump if the relay got stuck and continued to run. Locate the pump, remove the wire connector and apply 12 volts to the terminals that had the heavier wires. Polarity doesn't matter, as it's just a motor. If it runs and pumps up the car, which I'm betting it won't, you have a possible wire or connector problem. Or the relay. Many other scenarios, but it's usually the pump and/or relay.
