Hello MB family,
I am new to this forum but plan on sticking around. I am hoping you all can assist me with an issue that I am having. My GL was vandalized (Tire had a metal rod put through it). So I tried to put air in it but was driving it around 20 PSI to two different shops to patch the tire. After a while the ride became very bumpy. Once I got to the second shop (since the first shop could not do it) I was informed of the weird looking metal rod. They had difficulty pulling it out as it took time because it was about 4-6 inches long (i should have kept it). I was hoping my ride would return to normal height but it did not. I noticed how bumpy the ride was so I tried to raise the vehicle after the repair (this was my first time trying). After trying to raise the vehicle I noticed that it was taking longer than normal to raise and a "Cooling down" and "malfunction" appeared at different times. So I proceeded to drive home with the car raised some but eventually it dropped again (while driving) but never touched the tires. I waited about an hour and tried raising it right before the tow truck arrived which it did but I got the "Cooling Down" message again and I noticed that both times it took much longer to try and raise. So my question to you guys is what are the possible ways this can be related to the flat tire, riding on it with low tire pressure and also trying to continuously raise the vehicle automatically and manually (push of a button) after the fact ? The dealership informed me that my airmatic compressor, relay and valve block went bad. So can you guys inform me on how this is all relative because the tire situation started it all?
Thank you in advance!
I greatly appreciate it!

Mercedes is currently saying nothing is wrong with the airbag. Just the Compressor, relay and valve block. It was taking a very long time to lift the vehicle after the tire was put back on with the patch. That is when I notice the "malfunction" appear and also "cooling down" I don't remember which order though. So, could lifting the vehicle after the tire incident burn out those components?
Thanks again!
Thanks again!
On my previous airmatic equipped vehicle these symptoms were the sign a broken axle height sensor. The little connecting rod is plastic and it breaks with age or in your case, perhaps because of the trauma with the tire. The sensor needs to be physically inspected because the Star/SDS system may or may not pick it up on what position it was in when it broke.
