When you removed the fuse, power was interrupted to the ABS/ESP controller and it needs to be reset (e.g. same as what happens when you disconnect the vehicle battery).

To reset, with the engine running, turn the steering wheel completely to the left and then to the right and the malfunction lamp should go out.

That did it - thanks!

I am not an expert by any means but I did just experience the same issue. The way that I solved it was by reinstalling the original one that I attempted to replace with one I got at autozone which was not OEM replacement but their best guess to what is compatible with the vehicle. Trick is you must turn the wheel all the way to the right and then all the way left and the lights should clear. If they do then click the ignition off then you will see the malfunctions still present but once you power the vehicle back on and off that should clear.You may have to repeat this process a few times. This should clear the code unless the brake light switch has in fact fouled out in which case you must go with the mb OEM replacement part. Hope this helps.

OK

yes slightly off makes a difference, all the way to 1.5 degrees due the the electrical steering system. Even if you are slightly off go somewhere and have them put it to center.

Go to hardware store and buy a roll of black 1/2 to 3/4 inch electrical tape, cut a strip about 1 inch off the roll and proceed to place it over annoying light..
Wala problem fixed!

• [QUOTE=marcomassimi;4256384]My wife drives a C230K

I get that BAS ABS ESP message every time I'm driving the car. When my wife drives, she never gets it. Clearly it happens when I adjust my seat down (not back, I mean sinking the seat down with the lever on the left of the seat). As soon as my wife gets back in the car, adjusts the seat back up it all goes away.

There is definitely something wrong with the harness underneath the driver's seat. So I decided to test this theory. I drove with my seat jacked up. Sure enough, I did not get the message.

I disconnected and reconnected all the harnesses under the seat one day, making sure all the connections were good. The problem went away for 2 weeks, until once again reappearing.

So I would look into that harness before attempting any more pricey fixes.[/QUOTE

Thank you Marco, I did everything like you said and problem disappeared, just move drivers seat up and tried driving my car around couple miles and no more messages!!!😆

same thing happen to me no code to reset but I just fixed it turn the car off and pump the brakes till it becomes tight to press. Then remove your foot of brake then turn the car on see if the error goes away it did on mines might only be a temporary fix

LateLife Crisis

Hi, recently had the abs/esp/bas warning lights come on my 2001 clk430 convertible when I broke traction with my inside left rear wheel turning out of a junction, they basically come on now as soon as I turn the ignition on or start the car. Tried the reset of turning the wheel lock to lock even after a battery disconnect, didn't work. Pulled the brake light switch out, disassembled and tested electrically, see my thread for details. All ok and brake lights operate as normal and brakes seem to be operating as normal but obviously no ABS at present. The cruise control still operates correctly which makes me think the speed sensors are ok. Tried to get the car code scanned but I live in rural area and the two independent garages couldn't access the abs/esp module which is pin 6 from memory on the 38 pin round diagnostic port. I have the icarsoft 38 round to obd2 multiplexer adapter but although it gets me into some of the body modules doesn't access the abs/esp module. My semi logical brain is pointing to the yaw sensor hopefully and then to the actual esp module. I'll try and get it star scanned if possible. Any help would be appreciated. 😊

All good found low supply voltage at abs pump but good voltage at relay behind main fuse box, noticed non genuine electrical tape on loom, jiggled the wires around and all the lights have gone out . Need to take apart and do a proper job instead of the bodge at present.

Hey bro I'm wondering did you ever find the issue with this problem?if so what was it?
I have same issue abs bas esp light stays on.
I got reg diag scanner no codes. Then had a mech with espensive scanner read abs and dtc codes left speed swnsor, right upper o2, oil sensor.
now I know o2 and oil sensor has nothing to do with abs but I still changed them out.
Plus changed speed sensor, brake stop switch checked all fuse and relays. I even changed out the abs pump module with pressure switch.
I still have abs bas esp light on. Oh yeah even did reset by turning steering wheel all the left then right and stuff like that. Still lights on.
Now I know if ant speed sensor out I would not have cruise control now I do bc I changed left speed sensor.
I know if brake stop switch bad I would not have brake lights and or 3rd light but I do.
i do t think it's steering wheel angle bc that code would have popped up correct?
I'm a little stumped at this one I think k now electric wire from abs module to dash somewhere is shorting out somewhere.
I believe this bc my horrn fuse which also known as(fanfare) fuse keeps blowing.
If you or anyone help in my situation? Thanks

2001 CLK320

New here. Been browsing for a few months after I bought my 01 CLK 320.

Had this same problem, replaced switch, checked fuses, bulbs etc, and I’m pretty sure I read a previous thread where you stated this fix with the seat, and it worked for me (thanks btw). Light went away when I changed seat positions.

Definitely worth trying.
