ASR help needed - PLEASE!

Hi guys! Yes, I have read every post I could possibly find on the topic, as I know you guys are quite sensitive when it comes to not using the search function! The problem I have is not described in any of the posts I have found and read.

I own a 1992 500SL LHD and it was imported to South Africa from Japan from what I can gather. The odo currently reads 168k kilometres. The car performs fine at low speeds, but soon as I go over 90km/h the ASR kicks in erratically. The braking system (from what I feel behind the steering wheel) is activated, and the car becomes very unpleasant to drive. The ASR and ABS lights also light up on the instrument cluster when this happens. It almost feels as if there could be a wire that is shorting somewhere. I have checked and cleaned both the front speed sensors to no avail... The car still does the same. I then searched the forum on how to disable the ASR system, which is my ultimate goal. Not being a Merc specialist, I found the switch mod, but couldn't locate anything that resembled the computer boxes described and pictured in the thread shown. Needless to say, the ASR is still a huge issue. The car has been garaged until I can sort the problem, which hopefully will be soon...

I would greatly appreciate it if anyone could either assist me in installing the ASR bypass switch (describe what needs to be done on my specific car) or tell me what the 'quick fix' for the problem could possibly be..

Any advice would be greatly appreciated..

Hey guys! Thanks for the feedback. I am riding 285/35 ZR 18's at the rear and 225/45 ZR 18's at the front. I remember from other posts that the tire size causes issues.. Do you think this is my problem? I do like the look though and would still appreciate it if you could tell me how to turn off the ASR... I neglected to add in my previous post that the problem seems to be worse when I drive on a bumpy road..

Well the tire sizes should not be the root of the problem as there is only a 4 rev per minute difference between the 2.

The easiest but most drastic method is to remove the ASR relay!

From memory, it's in the front LH side of the engine bay.

EDIT: have you checked out this topic? http://www.benzworld.org/forums/r129...92-600-sl.html

No trees were harmed creating this message, however some electrons were very inconvenienced.

Hi! Thanks, most appreciated. I'll check it out. Can you possibly tell me what the relay looks like? Would it be one of the ones located behind the fuse box?

did u check the rear sensors?

i read that u checked the front sensors for cleanliness but no mention of the rear or of any electrical check. i came across this link which outlines how to check the sensors ..........

http://www.benzworld.org/forums/r129...rential-2.html

you might want to run a quick check as described - if all checks ok then u can eliminate the sensors and sensor wiring as the source of your problems.

i personally would spend the time and money to fix the asr/abs system rather than disabling ......... just my 2 cents worth. anyway good luck - let us know how it pans out.

Having done and won a battle with the dreaded A$$ Reamer (ASR), I agree with finding the gremlin. The above is a great place to start. I followed every thread I could regarding disabling, over riding, fooling the system. No one really seems to have a definitive answer and successfully disabled it. Probably better, safer and cheaper to just make the system work as designed ! Keep up the search !
