I had the same issue and they said it was the crankshaft or cam sensor. Ended up being a misfiring cylinder. Had it replaced and it starts like it’s brand new.

My 2000 s500 is doing the same thing now. I tried to start it a few times and stopped. I'll try your method now, give it some time to see if a blessing falls out of the sky. 👍

I have a 2003 Mercedes S500..my car had the same issue..wouldn’t start for days then randomly would start..there was an issue with the damaged FOB I was using and the car wasn’t connecting to the FOB. I used an extra FOB with new batteries and now my car starts. Also, if the inside of your FOB is dirty, it will cause the same issue, it needs taken apart and cleaned. Hope this helps.

Hello good, I have another Mercedes Benz like yours and I get the same fault, can you tell me what happened to yours? greetings from Spain thank you.

wire or ground point corrosion can cause such problems or the fuse board would push a small wd40

I have the same issue 🥺 I almost broke my car today with my own hands😅

I know im late.. if you removed the battery and esp and bas lights come on ..all you need to do is to a turn the steering wheel all the way to the left and immediately turn it to the right, then back to the center position ..( do this kinda fast).. that will resynchronize the sensors .. then get out your obd2 scanner and plug it into the port under the dash on the driver side .. see what codes are showing .. it looks like your ignition switch and key are not sync together..ignition switches maybe a issue.. but look for obd2 codes first !!!!

We have a 2000 S500 with the same problem of not starting. We let more time go by but still no crank or start. Checked with Info Scan/OBDII and have No Codes. What Relay did you replace?

proposes to remove the ignition switch and leave it on the warm radiator for some time, when it is warm, install it and check if the car fires. in my case it worked and it was the ignition switch that was to blame. PROCESSOR IN THE STATION FOR REPLACEMENT AND PROGRAMMING

Any luck? I'm having the same issue

find the problem ? running into the same thing. Everyone is saying crankshaft sensor or ecu ?

i have a 04 s500.. my taillights stay on and the battery ends up dead all the time. once i jump it, it runs smooth until the srs message pops up and radio shuts off, turn signals don’t work, and much of the electrical things like windows won’t go down. i’m not sure what the problem could be..

My friend, everything works, even the lights of the buttons are on, but the engine does not start.... What is the problem?

Scan the car, it will tell you what the issue may be. If the gear in which the car is in (next to time display) does not show it is likely the gear selector or the EIS

how do you fix this? I have a 2000 s430 same problem, anybody please help

the noise is coming from the pump for the airmatic suspension.

Had the same problem with my S350, car wont start after i replace the battery, first time it was fine then after i took it home it wont start. It was the starter motor. The computer does not power the starter motor if its damaged to prevent it from damaging the engine

Starter malfunction

Try Scotty Kilmer ASAP

Take out the starter motor and clean it with electrical cleaner and make that you disconnect the battery before take it out

Sam or computer issue you fried something

Turn steering wheel to the left and hold 5 seconds, then to the right for 5 seconds, then back to the center and it will go out
