2000 Mercedes Benz S500
I really need some help, or advice!! Please

Ok so I just bought a 2000 Mercedes s500 about week ago... of course it's older, it's had its problems but it's well taken care of. But it did sit for a while.before we bought it. Ok, so today I'm on interstate notice only going 60 my RPMs are at like a 4 and felt like it wasn't wanting to switch.. so then that just worked its self out, next thing I stop at the gas station. Come back out and get in. Put the key In, turn it.... it looks like it was going to start all lights worked air worked, dash lights were on, a d the electronic reading on the dash was all ON. But the car didn't do a thing. I don't know what to do!! Just bought it, I'm already getting screwed! Any ideas, or advice for me what to check to try n fix it would be greatly appreciated!! Thanks in advance!!

Could be many things. Sounds like you should probably take the car to a knowledgeable Mercedes tech and have it checked out. One of the most expensive things you can buy is a cheap Benz...

BrittCork, try replacing battery(ies). Flaky batteries create strange symptoms. Especially since you mention the car sat unused for some time.

Hey guys
Same symptoms in a 2013 sl550. Now at dealer for the third time to fix. Intermittent too. Not repaired yet but i'll bet this helps get us there. Thanks for your detailed postings.

Your 231 has a much different battery system than the 220 referenced in the OP, you are probably better off starting a thread in the 231 section for your problem and outlining your exact symptom pattern. It could be a battery but it's highly irregular that a battery be intermittent, they don't come back from failing.

Have you had the car scanned? The self diagnosis capabilities are greatly improved by your year and will at least point a good tech in the right direction so you don't waste too much time or money on tracking down the issue.

Already posted in the 231 section. No one has any ideas. found this post because of the error code 30g, one of the codes retrieved by the dealer. Exactly the same symptoms though. the problem is intermittent in that it arises after the car sits overnight, then after starting and revving the engine for a while (or maybe just passage of a few hours....can't tell) works well enough to go to dealer. twice they said it was a dead main battery. first time replaced it, second time disconnected the bladder pump for the seats saying it was running all night because of a hole in the bladder, and drained the battery. about two to three weeks between episodes. this time it stayed at the dealer until they got the problem when they started it in the morning, and they read a 30g error code. no word after almost a week as to what is actually wrong with the car. btw, when you have this happen the wheels lock. they have to put dollies under the wheels to drag it out of the garage and onto the tow truck. most tow companies in my area don't have the ability, but I found one who does, and who is an MB enthusiast with a 231, S sedan, E 4, and who does his own work. he was puzzled by the problem as well.
Any help you can offer is welcome. the tech at the dealer has obviously been puzzled as well.
