2002 500s, 141k, purchased a week ago. suspension drops on one side when parked, ABC Visit Workshop comes on and off. Where do I check fluid level, and the procedure to drain and fill with new fluid.
And just so I get it, could you explain how to do this as if you were telling a 10 year old.
And thank you in advance.

what is the part number for the starter motor in a mercedes benz s500 1997

I have a 2002 S500, [132K miles]the Air Matic has been acting up for months. Particularly when it is cold [below 30] the car would lower all the way around. As soon as the car turned on it would elevate to proper level. Next observation was that I would hear hissing every time I turned car off. Finally the air compressor would not click in and the Red, Stop Car,Air Matic light comes on...and of course the car is lowered all the way around, the rear lower than front....I think it is the compressor pump but reading the other posts and viewing You Tube videos a variety of fixes appear....such as
1.) Replace Air Pump Air-Matic pump (p/n 2113200304)
2.) Check for leak in connection hose/replace hose with new style hydraulic hose...says don't use old hose,it leaks.
3.) Check 40 amp fuse/relay (fuse 32) if replace relay (p/n 2542131)
4.) It may be the S500 AIR MATIC SUSPENSION RIDE CONTROL MODULE, if so replace it.
5.) Also all of the struts appear to be fine.I don't think any of them need o be replaced. [How do I verify this assumption?]
6.) I replaced the Air Matic two and half years ago at an approximate cost of $1,750 at MB dealer.
7.) My desire is to get it fixed for a lot less then the $1,750...example: last month, the local Firestone shop repaired the crank shift sensor for about $100 total...the dealer wanted $600...
8.) If I know what to tell the Firestone repair shop what to look for they can fix it for about 75% less. They have done multiple repairs on my S500 that the dealer would have charge 3 to 5 times more.
SUMMATION: In what order should I check for problems with the Air-Matic; can you give me a probability from first to last what I should check, i.e. most likely cause of issue, problem first, then second most likely problem, and so on.

Who ever answers this, I sincerely appreciate your advice, response and the time you took to help me out.

when Iturn on the ignition the fault light and the left signal light comes on and wont go off Ichecked all the bulbs and they are ok

the faulty light warning light and left signal light come on when ignition is switched on and wont go off I checked all lights and all ok any ideas

I checked all the lights and are ok what could be wrong

at times it shows perfectly but most times it all scrambled

Brakes are sqeaking and ESP malfunction and ABS malfunction lights are on.what could cause this problem?

what could cause the ESP malfunction and ABS malfunction light to come on?

My car is lower to the ground and it sometimes scrapes the ground.

An error message came on, something about needing to format something.

WHEN EVER I HIT A BUMP I HEAR SQUEEKING NOISE AND A KNOCKING SOUND BY THE RIGHT WHEEL

I start the car, no problem, when I stop at a light or in traffic and then I step on the gas it stalls or hesitates. Then the check engine light comes on, I go to mechanic and computer show a #104, we change the air flow sensor, two days later same thing happens, go back to mechanic computer shows #104, again... HELP !!!!!!!!!!!!!!!! don't know what to do.

I was doing a google search to look for a problem with the auxiliary fan motor and came across your website, it had highlighted the search I was looking for but couldn't find it. Just wanted to see if this was a problem Mercedes would fix or if I have to do it on my own

Please note that your model listings do not contain S350 so I have had to list as an S500 to submit. Mercedes have looked at the car and could find nothing. They suggested it might be engine mounts. The noise and vibration goes once the car warms up. It's a W220 chassis, last Australian delivery of the pre 2005 model and has done 40000 kilometres.

Engine light just went on ? Engine runs a little rough - but once warmed up - she runs fine ?? Engine light is on when car is running ????

Serpentine belt is on OK
I see no broken belts -- any more belts other than serpentine?
Any idea where to look, or should I just tow to the shop

when you leave it over night it run the battery down,can disable it by takin the fuse out?

System acts like it's muted but the muted button is not depressed. Music was playing fine while parked, key was rapidly turned off then back on and the SOS phone button depressed (no phone conencted, nothing in dock) for radio, then no sound. Tried disconnecting batter (never doing that again) still no audio w. Check fuses all look good, even f61 & f66. Please advise on how to fix. I think maybe the keyfob buttons were pushed in some combnation to mute system: IDK Thanks, Kathy

If so would love to hear about the issue and the resolve. My keyless-go has a problem with “Keycard not recognized”? it sometimes starts the engine but cuts out within a second.
Doors lock and unlock all ok.

Whenever I start the engine and allow the vehicle to idle it leak fuel from the charcoal canister.

Problem began after a leaky transmission seal was replaced.. Tech admitted that a vacuum line was
Detached but replaced without apparent damage

2001 s500 Just got this car week ago from engineer that told me he has own this car for 10years, i check everything (so i tough) i forgot to check if cd was working. I notice that when I press cd (radio) keeps giving me no cartridge? I check and was in, I tried to eject and will not. How do I fix this? I read some info in web, allot of comment about cd cartridge worn out, its known trouble, one suggested removing battery and system should re-boot and will recognize cd? This I am hesitant to do. Any suggestion. OR SHOULD I JUST GO FOR AFTER MARKET BLUETOOTH AND CONNECT TO RADIO?

I have 188,000 miles on the vehicle.
