[Clueless E55]

I just got an E55 AMG from 2005 a week or so ago. The seller notified me that the battery is bad. I had the battery tested and it’s not bad. But it gives me a red pop up warning in the instrument cluster that says “service battery, conven functions temporarily disabled” then my AC will shut off and turn back on 15 or so seconds later once the message disappears. Then it comes back on some time later. I noticed it doesn’t happen when I’m on the road and not stopping like highway driving, but if I’m stuck at a light or in a drive thru it pops up.

Secondly. I left the headlights on for like half an hour, I know it has an auto feature, but it was accident. when I started the car after shutting them off and my head unit wouldn’t turn on. I’ll press power and the MB logo illuminates but then goes away after about 30 seconds oppose the the usual 2, and instead of turning on it just goes black. I know it’s not the command unit.

And lastly, the airmatic suspension. The owner notified me that the car has an air leak. He said that it’s in the rear only and it’s the rear passenger airbag. The whole rear end sags tho, and also he said he got a regular shock from a junk yard and replaced the rear passenger one because the airmatic suspension breaks often. That can’t be good for the torque, speed, drifting, and burnouts, and cornering I’m doing with this car. To have one wheel that has completely different suspension characteristics than the rest can’t be good. I can feel that it corners very unstable when turning left. It must have something to do with that junk yard shock.

I’m not mechanical inclined, and owning a AMG MB when you’re not mechanically inclined, and also don’t have loads of cash can be difficult. I already have high ass insurance, and gas cost. But that’s why I turn to BenzWorld for answers. Maybe someone out there knows something about my battery or stereo issues that won’t run me up thousands when serviced at an MB center.

Sounds dangerous, the suspension sounds like an accident waiting to happen.
Poor car has had a bad time with its PO by the sounds of it.
You might consider posting in the AMG W211 section too.

Find sombody with SDS Xentry and have it scanned or get your own otherwise you will be lost with all these issues.

Wait you bought an E55 with known electrical issues, bad air suspension with no possible DIY repairs and no cash in the bank to get anything fixed?

At 15 years of age. the suspension air bags are definitely due for replacement and since compressor was grind for some time- rebuild it.
The electrical problems sounds like alternator brushes aka voltage regulator, but check and clean all electrical connections from the battery as computer is very sensitive.
I hope you did your homework before buying and are familiar with common wisdom >>> "there are not many thing that can get expensive as fast as cheap Mercedes Benz"

Your user name is very appropriate👍

Do you do your own maintenance? If not, then you should. Pick up an SDS setup and diagnose that car. That's first.

Second, get some tools and put your thinking cap on. You're going to need to do some troubleshooting based on what SDS is telling you.

Third, whatever needs to be replaced, buy good parts, not the cheap crap on FleaBay. Get either Genuine-MB or actual OEM parts for any repairs.

Once you get this car into good repair, you're going to love it. But you need to first get it into good repair, and that means doing it right.

For the battery issue, check or have checked the aux battery located in the engine bay, passenger side rear, under the cabin filter.
