Because the fault code still exist in your car computer, you can take your OBD2 code scanner to erase.

SOURCE: 1994. MBz, s600. v-12. ASR. dashboard light.

The ASR (acceleration slip regulation) light is for the ETA (electronic throttle actuator) it is a mysterious beast that controls throttle placement. I would say that you have one of two problems. Either the interior insulation of the wiring of the ETA is is crumbling or the wiring harness is disintegrating. Either fix isn't cheap although if I had to pick one I'd pick the wiring harness. It's about a third of an ETA. In short check he wiring to the ETA, look for damage or water intrusion, if nothing is found you will have to replace the ETA control.
READ THIS POST FROM A M-BENZ FORUM MEMBER ON ASR ISSUE
For two years I lived with the the ASR light coming on shortly after starting the car and had to either continue driving it in the limp home mode, or stop the car to restart it to regain normal engine operation with the ASR light out. Finally, it got so bad I simply took a chance, after discussing the problem with a reputable local indie, and bought a rebuilt ETA from Potomac German Auto and put it in. The part had a one year warranty with it and was about half the cost of a new unit from MB. There are other companies out there that rebuild these units as well. At any rate the ASR problem went away. To give you a reference point, my car had about 156,000 miles on it when I did this repair. That may or may not be significant to your situation, and I probably should have corrected this problem well before I did, but I didn't.

SOURCE: On a 1995 S500 Mercedes , ASR light keeps coming on

yes they can but unlikely-more likely a bad over voltage relay(powers up idle speed computer) or wire harness-your vehicle is probably a hfm type fuel injection they changed from lh that year. find out if it is lh check the fuses in the base module located in the passenger side of the engine compartment under a cover held in by 4mm allen head bolts-alot of times these control units have intermittent contact with there connectors. asr stands for acceleration slip regulation-both isc and asr communicate via can system to monitor throttle position- ea isc cc-idle speed cruise control and electronic actuater(throttle)-hopefully i have helped

SOURCE: the asr light is on and the car does not

the o2 senser would not cause the a.s.r. light to come on-there is only 2 things that the engine module and the a.s.r. module have in common. 1 is the e.a. actuater(throttle) and 2 is the base module. most likley either your acuater has to be resynchronized or the actuater itself is bad. have codes pulled from your h.f.m.,a.s.r.,e.a-i.s.c.-c.c modules and see what the codes say. You will probably find that they say e.a. actuater module is defective. the pig tail connecters go bad and they need to be replaced just be glad you do not have a 600 series because they cost about 1200 a piece and the v12 have 2 of them. If it is defective and you cannot resynchronize it there is a company that rebuilds them for about 1/3 the cost of a new one- good luck

SOURCE: What does the BAS ASR light mean in a mercedes

brake light switch ,that's the part you need to replace to fix that BAS/ASR light. It's a $20 US part, a screwdriver, and 15 minutes to fix.

Check one of the fuses in the bonnet. There is most likely an electrical contact problem. You will need a fuse wire replacement

We have a 1993 Mercedes 400 SEL. The climate control unit has a problem where it will keep turning on and killing the battery.We have been disconnecting the battery cables every time we shut down for more...


The ASR and ABS are voltage sensitive, so each time you disconnect them from power, they will reset. To cancel the ASR light, start engine then turn steering wheel full lock to right, then lock to left...ASR should extinguish. ABS light should then go out once you drive above 8 mph for 100yards or so. Until you can have the climate control looked at by a professional, I would locate and remove the fuse for it when you park up. Much better than disconnecting battery.

I have a 95 mercedes benz 600s and the asr light keeps coming on and it won't shut off even when i hit the button. any suggestions on how i can disconnect it for good.


Your ASR light is on for a reason, if it won't shut off with the switch it has been tripped by another system. Have your brake switch checked its on the back of the brake pedal. Next have ABS wheel checked. ASR was replaced by ESP and neither system can be shut off completely. If the ASR light is on there is an error it IS OFF.Hope this helps
