Had my damn ABS, ESP and BAS lights come on again in my ride on the 405 today. Looked back at my receipts and I had the stop lamp switch replaced just over a year ago (special thanks to Bosch for their inferior electronics). Light seems to come on after the car is started and the brakes are applied. I decided that I would attempt to repair it myself versus paying the stealership $75 for a 15 minute repair job. Stop lamp switches run about $15-25 at the dealership and the switch is fairly easy to access after removal of the plastic access panel under our dash. Curious if anyone else has done this and if I need to disconnect the battery after the install to reset everything. I will digital photographs to help others that try this in the future. Realize though that the problem could potentially be a wheel sensor so we'll see what happens and if this fixes it. The error code is 1584 for a faulty stop lamp switch for those with access to diagnostics. Will hopefully save me some $$$ this time!

Picked up the stop lamp switch today and installed it and it seems to have fixed the problem. To replace the switch, you will first need to remove the 4 phillips head screws (see pic one) that hold the access panel in place. There are three along the sides of the panel and one near the hood release handle. You will then locate the stop lamp switch by following the brake pedal up until you find a black pastic switch with two small wiring harnesses connected to it (see second pic). Remove the switch by pushing the attached pastic lever and rotating it clockwise. It will then free itself from its position and you can remove the two harnesses. Installation takes place in the reverse order. Took me 15 minutes for the job and another 10 to sip a cold beer afterwards. Cheers!

Too cool! Thanks for the write up and pics. Moderator how about putting this in the how to's.

After replacement of the switch, you will want to pull up on the brake pedal slightly to set for proper adjustment of the switch. MB use to have you put a 2mm spacer (2 radio key worked) between the switch and stop for correct adjustment, but they changed the design so no need for the spacer.Just wanted to give a little extra info, but you provided some good DIY info .

What about it ricky?

Anyone know the part number for this switch?

You guys gotta PM me or something about merging or whatever, I rarely check this forum.

As for integrating it into the How to, I think it'll serve a better purpose as a seperate thread.

You do of course realise that thanks for white elephants like TOW thread that grow for no good reason that this thread will eventually be pushed out of this forum like some many other useful pages about modding.

Nice Job Bbearden, I had the same problem with my 2001 CLK55 24,000 miles. I followed your recommendation and the easy change of switch seems to have fixed the problem. Cost me $22.95 for part.
Thank you!!!!

bbearden

Glad I could help you out! I don't get worried when I see that light flash these days, knowing how simple the fix is.

zonajoe

Any other easy fixes in your bag of tricks

bbearden

None other than typical routine maintainance.....fuel/oil/air filter changes. The MAF sensor is an easy fix as well when it goes. Always a good idea to carry a can of CRC mass air folw sensor cleaner in the trunk if you get caught on the road with that problem. Its a good temporary fix until you can get a new sensor in. Thats most of the problems your Benz will have that I have noticed, other than an another occasional electrical gremlin.

very helpful thanks

I agree that this should be part of the How To. I have also encountered this problem and will want to look it up. It seems like a lot of other people have this problem too.

Just copy his post, along with the pictures, and insert the part # mentioned in another post to the How To sticky in this forum.

ad me to the list of repaired BAS ESP ABS malfunctions.
I got tired of the three malfunctions everytime I started the car and stepped on the brake pedal. $24 for the switch from the dealer, they have them in stock since it seems to be such a common problem.
5 minute repair and all you need is a screw driver. So nice not to see the yellow lights on the corner of the cluster

$17 bucks and some change....and I got this DYI done today. Thanks bbearden for the great write up.

note: I have a 2000 and my stop light switch has 2 big white color harness plugs rather than the black plug and that silver prong you see in the above picture

CurYousGee

dayam its back!

ThrillKill

It's probably a wheel sensor. Took mine to the stealer as soon as it happened. Cost 3.6 billion dollars to fix but it never came back.

CurYousGee

sucks....oh well....i'll try them when I get a chance. Thanks for the input....back to the bas, esp being on again and off again.

I think my CLK has the same problem. Did the failure of this switch prevent the car from being moved from park?

newguy2008

My CLK has been doing this on and off as well for a year now. I'll get around to changing this soon especially since someone here was nice enough to take some pics explaining how it's done.

It's been a minor annoyance.

Thanks.
