Weird as it's intermittent, if something was leaking, it would doing all the time I'd have thought...??
Sometimes it goes a week without dropping, sometimes it'll drop every time I park it during the day....

As you already know there are too many codes to deal with. You will have to find a mechanic with a Mercedes SDS Scanner to read the codes.

Under the hood in top of the suspension mount there is a vacuum hose that goes into the air shock that has a brass compression hex nut. I think it’s a 10mm. I hear that those can loosen and leak.

See if that’s loose.

Every time I shut my 63 off when it’s in comfort or auto it goes down and rests on the bump stop. I hear a woosh when you close the door or if you sit in the car after you turn it off for about 20 seconds and it drops. The only time it stays up and not got down to the bump stop is if I press the raise button and it’s completely raised.

I bought the Autel scanner as all I've seen people saying this is definitely the best one etc etc...
But having now used it, I'd say that Carly is the better option, it knows there is 70 ECUs in the car and it will get an answer from almost half of them....
As you can see, it has checked the Airmatic ECU and it is showing no faults... And never has done...
So, no idea why the car is dropping like this...

I think the problem is that you have the Autel MD808 which only scans a few systems. My understanding is that you need the Autel MD802 Elite in order to scan all the car's systems. But I have no hands-on experience with the Autel units. I am only guessing based on reading the experiences of others in the forum. I use SDS myself.

Will check that, thank you....
Yeh, mine seems weird as it doesn't do it all the time, sometimes when it does, it can be one side or both, it only happens about 40% of the time too...
But yeh, I always here that woos of air tho as I'm walking away from the car...!!

Well, i did do a bit of homework before I bought it, you can see the model comparison on Autel website as to what each model does and doesn't do, looked to me like the 808 did everything the 802 does and more, there was about $10 difference in price, hence I went for the 808....
I wish I could afford SDS lol, but tbh, for what I need it for which is nothing more than checking, Carly is perfect and seems to do a lot more than the Autel does...
If there is any issue, it goes to the mechanic anyways and he has Star and SDS...

As you can see in the pics, Carly covers pretty much everything.... Plus all the OBD stuff and Live Data, I believe that includes steering angle as well.......
Only thing I noticed that Autel does that Carly doesn't yet is Battery Management...
