Hi all, I just bought a 92 300 te 4matic wagon, the 4matic light is on and the owner said last fall it came on and per the manual he turned it off with the switch next to the battery.
I checked all tires and pressures, then found a torn hose going from the resevoir bottle to the pump. I repaired the hose, topped up the fluid, disconnected the battery for ten minutes, and took it for a drive.
Light still on, no 4wd. Suggestions?

Is the test switch on or off? On the resivor that is ur self leveling system. Also is the ! light on. It could be ur ovp really.

I got a Bently manual with the car, but on close inspection. it is for a 190! The resevoir is on drivers front inner fender and has a line going into belt driven pump, this is for leveling system?
The light that is on says 4matic, also the "bulb out" indicator is on beacuse the p/o removed the 3rd brake light assembly.
There is a knob in front of the battery, pull out and turn.
I read somewhere I can cause a blink code on the light to diagnose the problem. Should I do that next?

Red is ur self leveling system tank. Blue im sure is ur power steering. ur self leveling systempump is on that. is the back end ride bumpy?





Thats ur ovp relay. Never jump start ur car. mine was bad the !mark light was on 4 matic and check engine. All went away when changed.

Thanks! My 4matic test knob is just in front of the multipin box.
The faq sticky did not address 4matic, but I will keep looking.
Thanks again

Today I tried 3 different things at seperate times as an attempt to reset or read codes for 4matic, first I disconnected the battery for 10 minutes, nada-next I unplugged the 4matic ecu ,nada- last I jumped pin #5 and 1, but not even a blink in the light.
This car was allowed to run out of Hydraulic fluid for Iam guessing 200 miles, then I fixed the leaking hose and filledtank.
Suggestions invited.

The reference to the #5 pin is wrong in the service manuals. It is actually #4. A short cross will get the codes to flash. A long cross will reset the codes.

Today I jumped #4 and #1 and nothing changed, then jumped #4 to ground and not so much as a flicker in the 4matic light.

Are u sure the light is in the right spot. wonder if its ur check engine light? I would get under ur car check ur sensors in the diffs transfer and front sensors.

It is the 4matic light. It says 4matic on the light which is illuminated. An attempt at achieving a blink test did nothing at all to the light.

epowers777

What im saying is maybe someone pulled ur cluster and put the lights back wrong just wondering

Did you ever figure out this problem? My 4matic light is always on and I have been unable to get the codes. However, I've been using pins 1 and 5 not 1 and 4, so maybe. Regardless, ABS works, and there is no Check Engine light. When I short 1 and 5, the light just gets brighter while shorted and then returns to just on.

Help??
