thanks J, u where the brake switch is located ? its worth a shot

Manuyc

the break switch is about 10-13 bucks from dealer and berti00 and i can help you put it in. it is right under the strearing wheel/dashboard. You have to pull down the black cover under dashboard. look up break light switch on mb world there is a DIY

biggking

So this will cause it not to start?

@berti00 and manuyc, when u changed that switch push start worked again ?

Keep in mind this guy was saying he wasn't even getting the cluster to come on. Its doubtful that the brake lamp switch is at fault here. In order for that to even come into effect, the car would at least need to turn on, so in this case the switch wouldn't even be a factor in preventing it from starting.

The easiest "try something" at this point would be the remote batteries. Check to see if there is a little red light flashing on your key when you try to lock/unlock. If there is, the remote batteries are fine. If its anything more than that, its better to take it to the dealer and have them process the fault. Rather than sitting here tossing countless amounts of money on parts that may or may not be the problem, then just coming right back in this thread to say: "Changed this part that everyone said, still doesn't work." Every car is different. Granted, it could be a common problem fix, or some off the wall CAN communication problem.

I didnt but his was doing the same, so bought part at dealer with the family discount of course lol nd worked like a charm

What r u talking about ? Who's car won't start ? My works fine push start went out.

211.076

I'm aware of that. But the fact that everyone is saying to change the brake lamp switch for the push start issue, seems to be an incorrect diagnosis. In order for the stop lamp switch to even be a factor, you would have to at least be able to turn the car on from the push button. For instance, if you push the start button on the shifter, from your OP, nothing in the cluster was coming on or lighting up. That automatically takes the brake lamp switch out of the equation, because the car isn't even turning on at that point, so the brake lamp switch doesn't care whether you're in park/neutral. Do you understand what I'm saying?

AMG E Power

Yes I do, the Accessory ights don't turn on when you push the button once or twice without your foot being on the brake. It's only a 10 dollar part mine as well try right. ?

211.076

Sure. If that's what you want to do. I'm just telling you that the accessory lights/cluster has no correlation to the brake lamp switch. If the start/stop button was working, the cluster would still illuminate, regardless of if your foot was on the brake pedal.

I'm just trying to help. Mercedes-Benz pays me to work on these vehicles for 10 hours a day. I own an E55, and visit the board and just try to help out as much as I can from a remote location with limited knowledge of what is actually happening with your vehicle. You can take my advice or not. I'm a strong advocate of actually trying to get to the root cause of a problem and repairing it correctly the first time out, rather than just throwing parts at it in the hopes that one of them will fix it. I apologize if I come off as a little brash.

AMG E Power

No need to Apologize, all suggestions are welcome cuz I'm lost with this one. Will report back once it's fix. Thanks for the help guys.

dchl21

ill try this firs t

AMG E Power

Lol u must have not read thur the thread.

dyno

if it's just the K-Go Start button not working, meaning that K-go still works (and therefore your batteries into the key are fine)

then, it means that somebody has turned your shift-knob. maybe because he was trying to remove the knob and he didn't know how to. This is absolutely NOT to be done !!

or you will get the wiring of the button switch inside the knob shorted .

so, First rule is NEVER TURN/ TWIST your SHIFT KNOB !!


or you will find the same thing I found last week with my button:
... like this, wit hits wires twisted :



Uploaded with ImageShack.us


one more advice: NEVER try to turn back your twisted wires: they WILL BREAK !!

(.. happened this also ...)

Therefore, you'll have to:
- remove your trim panel
- remove the knob
- remove your button switch assy from the knob

at this point, just try separate them a little so as to avoid contact, but leave them there. do not turn them.
otherwise you'll have to repair/replace wires or replace the switch assy.

hope I understood your problem correctly and helped.

EGray@Germain

1) I spoke with my MB cert tech he said it could be a brake switch. He said try pushing on the brakes and if you don't here a clicking noise (like how you insert the key in the ignition) when you push the button then that what it could be.

2) He said it could be one of two the wires in the shifter from moving back and forth could be frad and causing short.

EGray@Germain

P.S. What part of FL you live in?

AMG E Power

u sir are a genius ! what u said makes perfect sense being I was cleaning my shifter knob with lexol. I was using a good amount of elbow grease to get it clean and must have turned it a little and the wires lost contact. this morning I twist the knob ever so slight and what do u know it fired right up with push start thank u so much cant believe a little twist would do that ! thank u to everyone else that chimed in u guys rock

don't get what's wrong with the word KNOB K N O B that it's being abscured ..

anyway, glad it helped ... but remember what I wrote in BOLD.
so, in the end maybe you'll have to replace the 2 wires .. but that's something feasible..

did I say NEVER TURN THE KNOB/ K N O B ?!!

and, DO NOT TRY TO GET THE WIRES BACK STRAIGHT AS WHEN NEW: they WILL break (because they are NOT mad eof copper but of brass)

t-bone

How do you remove the button assembly from the knob without breaking the wires then?

Manuyc

yup

Manuyc

it called break light switch
but it looks like you found the solution nice

dyno

I know my english is not great but I did not write that.

you are not going to break wires while you remove the button assy.
you are going to break them, after having removed the button assy, IF you'll try to straighten them back to normal.

Read again, carefully, what I wrote above.
