Hi there! This SL55 AMG that I am looking at purchasing has an... interesting ABC suspension issue. When the car is off, the front sags a little, the left far more than the right. However, when I get into the car and I hit the raise suspension button, it shoots right up with no issue at all, and it doesn't sag when I'm sitting in it for a while. Now, the battery is also going. Is this something that could be caused by the battery being an issue with sitting for long periods of time? When I get into the car it throws the "Convenience Features Unavailable" and all the things that go with that. Could that cause it to sag? I included pictures of it sagging.
Convenience Features Unavailable is from the battery. The sag is from a contaminated control block. You can clean them. Do a search for the instructional.

Thanks! Is there another name for a control block? I'm not finding anything online for that right now.
When you don't drive your car for awhile, the consumer battery in the rear will throw a light, and you will not be able to open the roof, you'll need to drive it around and charge it up to its proper level and then you'll get a message saying convenience features now available. As for sagging, check the strut for leaks, and check your valve blocks, maybe something is lodged in the line, you'll need to take it apart and clean it out.
