Hey guys thanks for reading.So here are my issues.I bought a 1993 300te wagon that supposivly the Head gasket was blown.Which turned out to be a clogged radiator and bad thermostat.I replaced both and now the car no longer overheats.Goes to about 90 and stays there.Now on to the next issue I have an ASR light on.But no ABS light.I cleaned the wheels sensors off which were covered in metallic chips.Still the ASR light stays on.I noticed a few bare wires but traced those back to the starter.The only issue i can notice visually is that my throtle cable is worn out.Would this throw any ASR issues?I checked the harness and all seams fine minus the starter wires being bare.Other than that I cant tell if the harness has been replaced.But any help from you guys would be greatly appreciated.

Issues:ASR Light stays on

things checked:wheels sensors on the front cleaned and reinstalled, checked wiring didnt notice any bare wires except for the starter ones.

Any help would be great thanks guys and I will keep you posted if not i am parting it out lol:crybaby2:

Build the code reader and check the fault codes on the 16 pin connector near the battery. There's both an upper and lower engine harness. Sounds like your lower (starter and alternator) is definitely shot.

Ok are there any links to build this so called code reader?I will definatlly look into the harness sometime tonight maybe this weekend.Will a bad throttle cable trigger an ASR Fault?And I partially traced the harness and couldnt see where it goes to the alternator.I Just know theres 4 wires that are completly stripped.I can get that harness for 150 bucks brand new.Anybody else have any opnions?

Do a search for building the code reader. Yes, a throttle cable can trigger an ASR light, along with dozens of other things big and small. The lower harness is $86 at parts.com, also fairly easy to rebuild.

You may want to look at these wiring diagrams located here: SUPPLEMENT 14 - W124 WIRING DIAGRAMS

ABS with ASR 152 152-1
ABS with ASR/Electronic Accelerator152-4

You will see approximately 35 wires connected to the ABS/ASR Control Unit with components or connections at the end of each one. Seems that about half of them go to the ABS/ASR Hydraulic Unit; with the others going to electronic accelerator control unit, OVP, Stop Lamp Switch, pressurizing pump, warning lamps, wheel speed sensors and the like.

You know ,, some have replaced the OVP to correct this problem and light goes out. The code reader can cancel a code like this too. Just build it, connect it, press the button a few times and like magic, the light goes out.

I'm pretty sure that until a code is cleared the light will stay on. You clear the code with the code reader. After you read all of the codes then clear them.

Go back and read them again to see if they were cleared or not. If not then you may want to post them here.

Now tell us that you understand how to use the code reader and that you have indeed cleared the codes.

Here is an excerpt from one set of instructions:"6. I went back to step-2 to read the first code, immediately after the 3 flashes I held the button for 6 seconds to clear the stored code. Then repeated this procedure for the remaining 2 stored codes. When I was done codes 3 and 8 were erased, but as Randy stated, 10 would not erase."

And I believe these are the codes for those pins: E320 16 PIN DTC Charts inc. pin 8, pin 14 - PeachParts Mercedes ShopForum

If it were mine then a brand new OVP would be on order and I would take the other ones to River Street and try to throw them to SC.
