RE: Do I have ESP (Electronic Stability Program)?

Its probably just as well its not a traditional mechanical LSD - as I understand it they can have undesirable side effects on handling in twisty corners.

My fusebox in the trunk seemed to be only german - I haven't tried removing the card. I know the tire data sticker in the fuel filler cap area is definately only germain - ditto for other similar stickers around the car.

First off i would just like to say that i found this forum very helpful in the last few days, thank you all. Well heres my question, i know this has been discussed many times in this thread but i would just like a quick answer, I just got a '94 500 SEL , i have two issues one more important then the other. okay well the important issue, on the bottom right of my dash i have the asr light, which turns on once in a blue moon when im driving on the highway (whats that about?) anyway so for a while now ive been looking for a way too turn off the traction control, from the thread i figured it doesnt exist (for this model). But i do have the "Snowy Tire" button next to the ashtray, now when i turn it on i will admit it does let me drift a little bit more then usual but nothing like i hoped. So is that all im gonna be able to get out of that button? (and it automatically turns off after 60km/h i think thats normal right?) My second less important issue, the car tends to overheat when i push it to the limit is this normal with these big engines? In its defense let me just say that i live in beirut, lebanon, Mostly Uphill roads, no traffic laws and no speed limits so when i say push it to the limit i really mean it. so take that into consideration. thank you for your time everyone.

Interestingly I was reading my '98 S500 owner's manual today to determine what the ASR light was since there have been many posts lately re. the ASR light being on. It seems like ESP and ASR serve very similar functions (detect unbalanced traction between the wheels and use the brakes and sometimes throttle to adjust) and now I understand that my car has ESP (with the ESP "off" switch) and not the ASR system. Since the lights and behavior are similar, it's easy to see how these two options get confused. It's not hard to get the ESP triangle light to come on in the center of the speedo with a fast start but it's goes off again pretty quickly.

One time (after a car wash) and then shortly turning onto a freeway on-ramp with pretty good acceleration, I felt the car do a sort of momentary braking action which could have been the ESP really kicking in. I assume that the wet wheels and/or road contributed to that behavior.

I would recommend you to read this;
http://www.pvv.org/~syljua/merc/Fahrdynamiksysteme.pdf
In german, but you will get a lot from the images.

The important things to note are;

ESP is ASR + yaw control
ASR is ETS + motor torque control
ETS is traction control by utilizing wheel brakes

If you turn off EPS or ASR, ETS function is still active.

The conditions where turning them off is beneficial
are; Snow with chains, deep sand etc.

EPS off will still be fully active (on) at braking action.

bzprince, please read what you have answered on once more... ;-)

As for the explanation of EPS vs ASR, page 33 and 35 from
the CL-Class Presentation Guide I put out the other day,
http://www.pvv.org/~syljua/merc/1998...tion_Guide.pdf
is a good read;

What he's saying is that ESP or ADS as MB called it for the W140 is different from ASR, ASR is traction control where ADS is stability control.

First, bzprince, look what you quoted, you said that it is not correct that ESP was
introduced in 1996 since you have ASR, but ASR != ESP.
(and please do not quote large images - I guess they are big enough as is,
let alone duplicates of them)

NZ Benz, ADS, is Adaptive Damping System != ESP;

AFAIK, if you have ASR, you also have the button. The button
can look like a wheel with snow-chains, or it has ASR written upon.
If you do not have this button, you have the ETS system.
Remember, ETS behaves much like ASR, but without the trottle
limiter...
