Hi, Please double check that your car is in the "P" or "Park" mode before attempting to use the key again. Please remove the key and re-insert and attempt to start again 3 times. If you have a spare key, please use that key as well. If this doesn't work, please call 1 (800) 367-6372 to get further help with your issue. Thank you.

You will need to trace the wire back towards the supply of power, could be a loose connection for example

It is called Parasitic Draw, one item is being left on and is draining power. Attach an ammeter to the battery. Remove fuses one at a time, keeping an eye on the ammeter. When you pull one fuse, you will see the reading drop a lot. That circuit is the one causing the problem. When you know the fuse, you can check all the things it covers. There will always be some draw because items like the clock and a number of modules are constantly powered. In general terms, you can't find work-arounds for problems like this, you have to fix them. Or, you can take the vehicle to a good auto-electrician.

The most common 3 reason why your Mercedes is running rough are a vacuum leak, an issue with the spark plugs, or a problem with the ignition coil. Clean out the throttle body and make sure there is no ware at the butterfly pivot shaft .

Sounds like you have blown a hydraulic hose that operates the top mechanism. You will probably need to find a local mechanic that is experienced with hydraulic operated tops or a dealership. But check you owners manual. Most manufacturers have a manual way of operating the top to allow you to secure it until repairs can be made.

check fluid level and all connections

It probably lost the rolling code, you need to find your owners manual and reprogram the system with your garage door opener, or the learning button on your garage door unit.

I think you could use this manual method instead.. My nephew use it to repair my car and it's totally repaired now. Here's the website he bought it from. reliable-store

If you're finding it difficult to service/repair your car, get one of those online manuals. You'll not have to wait for others to answer, or rely on mec hanics and all. Plus i know a website that sells very cheap but very very good manuals online, without expiry i.e. for lifetime. for this u can try reliable-store which is pretty good

I've had a few Mercedes and I seem to remember they had a fusible link between the fuse box and battery. It is a metal strap that will open under excessively high current.

Possibly chassis ground, loose, corroded, otherwise failing.

iring, schematic, electrical diagrams, torq setting, error/fault codes, full assembly/dissembly, service instructions and a lot moreetc are basic contents of these online books they here on this website https://big-manuals.com/

I would check the fuse box for a blown fuse

sounds like bad battery connection

It is at the back of engine , at bottom of transmission bell housing in center
