Esp/bas

[Yujin]

Ok, wtf.

The light keeps coming on, it is intermittent, but its starting to worry me. Have I neglected her in any way? Is she dying on me? Does parts need to be replaced?

She is a W202 C230K 2000. I baby the fuck out of her, but I also ride her hard, i wont lie.

Any ideas?

I usually just shut the car off and turn her back on and the lights gone.

You mean the ! symbol that comes on when tcs kicks in?

[Yujin]

No, not the triangle with the !, I know that means its working and Im skidding. I mean the actual warning light that is on the left side of the cluster.

[Yujin]

According to Benzworld, it is my break light switch, the physical switch under the break? Idk, Ill try that route if I can get the part.

It might help if you could tell us which light it is. Break light switch doesn't sound right. Break pad wear sensor? Break light bulb sensor?

[Yujin]

Its the ESP/BAS indicator. Not the triangle with the ! in it. Its the warning light, like something fucked up, like a check engine light.

Any ideas? Ill try to snag a picture when I get the chance.

[zmatt]

well that could mean a lot of things I think. Your pads may be worn, your abs may not be working right etc. I would get the code read to see what it actually is.

[Yujin]

Will the OBDII work with that light? I thought it only works with Check Engine lights

[Impressor]

im also having that problem...my bas/esp light comes on,the actual skid control no longer works n im also at a loss.im very interested as to how you sort your problem out.i was told that a wheel speed sensor could also be the cause...

[nhmercracer]

I may be mistaken, but I believe you should have codes with that light. Just like you get codes with the SRS light on. I think the CEL gets turned on with "P" (powertrain) codes, but not with always with chassis/body codes.

[Yujin]

I just bought a Break Light Switch, from what this tech told me. Its a DIY job from what he told me. Ill update when its installed.

[nhmercracer]

You'll spend more time getting the lower trim panel off and back on than you will replacing the switch.

[Yujin]

Worked like a charm in case anyone was wondering and for future reference.

[strictlyspeakin]

nice to see the final resolution!

The brake light switch is a common fault and is easy to do and quite cheap in runs alot of things the diognostic says mine is faulty even though no lights r on. But u do have to plug it in after u have fitted the new part to get rid of the stored fault. I had 6 stored faults cos the last owners mechanic was from the 1950's and didnt even have a scanner
