yeah.... nuts... I was hoping someone would have the answer... LOL I've been on the forum just searching and searching and so far NOBODY has ever had this stinkin problem. I hate this. The car still brakes but the pedal goes all the way down and leaks from those ports. so I may just tow the car over or take the back up part I have.

thanks man

okay.... dealership called me. Get this they said I need to replace the unit. THE UNIT WAS JUST REPLACED! I asked him how can this part break and his response is... it's very hard for this to break unless you get into an accident. I told him I've never been in an accident and that I don't see how this can happen. His response it's 2500 dollars to fix it. WTF!!! I don't believe it. no way two units are broken and leaking in the same spot. It wasn't leaking before I installed it so no *** way it's broken. I believe something else to be the problem. he said he couldn't pressure bleed it because it's leaking from there. UUUHHH DUH I know that. the damn system has air in it and the guy didn't even jack up the car because "It's too low" uuhhh i've taken my car in before with zero problems. I'm pissed and I know it can be fixed. When I told him I've never crashed so I don't see how this can be broken he said.... that's weird I don't know then. WTF! I'm turning to you guys because clearly they don't know what the hell is wrong. They want to charge me 120 for a diagnostic of something I already knew.

by the way this all started happening after the front brakes were replaced. I didn't put new sensors but I've never installed them anyways... this isn't the first time I do this so I'm extremely shocked this is a problem. What you guys think? I know the line closest to the unit has air in it because I can see when I placed the motive bleeder on the unit. I'm completely puzzled.

You may want to email one of the guys who are parting out their cars. If not them, a wrecking yard. BTW, when you pressure bleed your brakes, how many bar to you set the bleeder to?

toymr2trd

I went with 15. yeah where I got the unit I called them and this was the only one he had. he's willing to help me out and look for another one. funny thing is he's shocked too because it came out of a car that wasn't slammed in the front.

Is anyone finding it to be a pain in the *** trying 2 get the plastic harness things off the switch itself?

Vincent

replaced the swtich but the problem still there.... any other suggestions ?

tastoto

happened to me you need a new battery i had the same problem not anymore

Vincent

before replacing the lamp switch, tried charging the battery as suggested by the manual but didnt help.... the battery is about 2-3 years old.....

Thinking if this could be casued by the low brake pads..... but why would the BAS/ESP/ABS light come on instead of the brake light sensor (same light as the foot brake) ?

hi guys,

Recently purchased a 2001 CLK 320 Avantgarde and I now have the 3 malfunctions for ESP/BAS/ABS and shifter wont shift out of Park. I've tried the reset technique suggested but it hasn't worked.

Is this the switch problem that everyone on this post is referring to?

Also does anyone know if "Part number for this switch on my 01' W208 is 001-545-64-09 cost $13.80" will be the same part number for an 00' W208?

Paul

MarcusF

Yes, that's the problem and the same part fits 2000/2001/2002 in the US. It may be true for ROW cars, but I wouldn't know. If I had to guess, yes.

paulkktang

Yupz, you guys were spot on - stop lamp switch problem!
Got it changed & no more issues.

This has been a most useful thread - thanks to all who contributed.
The gear lock override button (under the 'D') was an absolute God send!

is this a common problem with these cars? i just replaced the brake light switch last year and it broke again. last time it broke, every single warning light came on on the dash, and it was night time so i was able to see that my brake lights would not turn off. today driving home, the bas, esp and abs lights came on, so i stopped to see if i could get the car scanned with the brake scan tool so see what the problem was. i went to leave and i couldnt shift the car out of park. i had someone check and my brake lights werent coming on. i got lucky and the dealership was still open so i sent someone there to buy 2 new ones (im now keeping a spare in the car). its not a huge pita considering its a ~$20 part that takes about a minute to change, but still, ive never had a brake pedal switch fail on me ever, yet this car is on its third since ive owned it.

I'VE HAD THE SAME ESP/BAS ISSUE WITH MY 2000 C230. SO FAR I'VE REPLACED MY BRAKE SWITCH AND BATTERY BUT IT STILL DOES IT WHEN ITS COLD AND THE SPEEDO WONT WORK EITHER UNTIL IT WARMS UP AND THEN IT RUNS FINE. ANY HELP PLEASE!

1998CLK320

You got a bad speed sensor man, welcome to my world.

I am in the proccess of getting it fixed, hopefully my indy can do it!

Is it hard shifting at all?

MI5

I just had mine replaced - brake light sensor.
It cost a lot at the stealer-ship. I wish I'd just taken the damn thing apart and replace it like everyone else did.

The battery, by the way, is old and pretty worn out (car's 10 yrs old).
How much does a new one normally cost?

I have a 2001 clk430, and The abs/bas/esp mal-function light came on. I also noticed that my Brake Lights weren't coming on. I did the turning of the wheel reset, but that didn't help. Went to drive to gt the Brake light switch, and couldn't change gear out of park. Found the manual, unlocking, switch for the transmission, pushed it in, and was able to shift out of Park. Drove to the Dealership, they replaced the Brake Light switch, everything is working fine now.

LYoung

will this work for a 2001 clk coupe and where is it located for my car.
Thanks

MarcusF

This may help.

3 brake switches and 1 K40 relay. Still getting the failure. Occasionally clears itself by turning it off and back on. What's scary is driving I-10 thru Phoenix w/o brake lights! I think it must be an intermittent short/open is the harness somewhere... Any other suggestions?

Leco_Diniz

Gentlemen,

I own a CLK430 Elegance, 1999. Only the ABS light is on, but the car wont pass 4000RPM, also, the ASC is disabled and i can't turn it on or off, but no ASB/BAS light on. The cruise control is also not working, this could be the brake switch?

The disgnostic machine said it's a communication problem between asc module and engine.

Thank you a lot.

wshepherd3

UPDATE 4/2/10 - Now, it's 4 brake light switches, 1 K40 relay AND a brake booster!!! Crossing my fingers and hoping...

BAS/ESP obsession problem crept into my car for a long time....i read on the forum that it needed replaced yet i chose to take it out first , open it and give it a good clean,the two connectors from the picture (sorry for the bad image,it was done with my phone)are the main ones as i could see there was something like burnt around the point were the two make the connection and i cleaned them carefully with very small sand paper number and it was ok.

...did even sprayed it with CONTACT SPRAY (clean electrical connections) and installed it again...It gave me immediatelly a "1 Malfunction" message and "BAS error Service Immediately"(also the brake lights were not lit at all completely when pressing the pedal)...realised the mistake i did and took it out again and saw that mabe it was a little too much spray added...cleaned that quickly and on the second install the tail lights WORKED again yet the BAS/ESP light in my dashboard was still on...though i didn't try to move the wheels all the way to the right and left hoping that may clear the codes...i will do that and see what happens...anyway i tried just because someone here said it may work but it was a good try though.

mabe a new stop lamp switch will work for me,also going to replace the brake sensors at the wheels just in case and while i am at it the crankshaft sensor too.

GusMorel

Would anyone care to tell me how to clean it? I replaced mine on my 03 CLK-320 and it only lasted 3 weeks. All the lights are back!

GusMorel

Hey, I just realized the right side of my brake lights are off. When I get the ABS-BAS-ESP lights, I also get a bad lamp message and my stop light fuse (15 amp by the driver door) is blown. Does this mean the whole mess could be the lamp???? I'm going to try replacing it to see what happens.
