I have a 04 S430.The brake wear message came up. I changed the front brakes, but how do I reset the replace brake message on dash?

Jezza

You need to change the sensors, the warnings clear themselves

c131frdave

Or jump it out. I'd jump it out so you didn't have to worry about it anymore...

Quadcammer

why bypass the sensor when they cost $7, take 2 seconds to replace and tell you when you need new pads?

c131frdave

Why not? Hey, just giving some options.

I am having the same problem, I've changed by sensors and the code won't clear........sooo months later still same code and now the sensors are $20 each at the stealer. I just can't win.

Jezza

You have done something wrong then, the codes clear automatically when you install a new sensor or short out the connection. It is just a circuit with a resistance test, nothing magical about it. No point bypassing the sensors for the cost of them though, they cost nothing.

c131frdave

jump the damn things out!

Quadcammer

seriously, we drive S-Class mercedes...not 1981 chevy malibus. This sensor is not some super complicated part of the car. If you want to go around half-assing it, just take the car to a proper mechanic so that your car's next owner won't have to go around and fix all of these half assed solution.

c131frdave

So you are better than a person who drives an '81 Malibu? Perhaps you should climb down from your high horse, pal- you're not. Just because you have more money than some folks cerainly doesn't make you better than them- especially if you are so lost with a simple two wire sensor that you have to take your car to a shop to get it fixed. I'll bet the mechanic might be driving that '81 Malibu, and trust me, he thinks your the dumbest fool walking the planet when you have to pay him $300 bucks to fix a friggin brake sensor...

Why the anger this morning you guys? This is a help-ful forum.

FRDave, if you have done much reading on here, you would know that a high percentage of owners on here favor having someone else do the work on her.

These cars have dropped in value so much of late, that I suspect most of the newer owners are more of a DIY mold because they either enjoy it, have enough common sense to be able to work on these cars or more-time-than-money (like me).

There is always more than one way to solve a problem in a car and having opposing viewpoints, presented in a healthy dialogue is certainly a decent way to share the experiences. I'm just surprised.
The sensors are relatively inexpensive, they work, but are they necessary....no. I personally don't think by passing them is half assing it, but then again, I have always been a RR owner and even those don't have such a fancy feature so what do I care if it is missing.

Back to the brake question originally, what type of pads did you go with?

Thanks,

Quadcammer

ok, is the oil level sensor necessary? How about the car too low sensor? Or the service due in counter? or the tire pressure monitor?

none of these sensors are necessary, but then again neither is satellite navigation, cooled massaging seats, radar cruise control etc. But I like it.

The car comes from the factory with a sensor, it is not a sensor that commonly produces faults. There is exactly zero reason not to put it back in. none.

Do it right or don't bother.

Quadcammer

When you ASSume, you generally make silly statements.

I just replaced the brake pads and rotors on my car myself, just like I do all the services on the vehicle. I replaced the sensors, and have no issues with them.

Any mechanic who charges you $300 to replace that sensor is a scumbag.

If you can change a tire, you can replace this sensor in under 10 minutes.

Hell if a benz owner near me wanted to replace it, I'd do it for him for free.

Its obviously not hard to change them, I'm just curious if the stealer gave me some bs sensors. The way my rims are I can reach in and change them without taking the wheels off.

Ok, I got a little hot yesterday, so I apologize. I live in Greenwich, CT, the most stuck up place in the world- and I hate that crap. So many of my friends think they are better than a lot of the poor people around here just because their daddy gave them a trust fund and they can afford a BMW or Merc. A lot of the poor people in this part of the country (mostly Haitians and Dominicans) are much better people than the rich *****es clogging the Greenwich streets. So any time I see anything resembling that, I get heated up.

To me, half the stuff on my car are unneccessary and just dig a hole in your wallet if they fail. If these sensors are problematic, I say eliminate them- they are not needed. That's just my opinion, and it is an option, but feel free to do whateaver you want.

Quadcammer

fair enough and I apologize as well.

That said, from my experience these sensors aren't that problematic on the whole.

Oliverk, and c131frdave,

Hats off to both of you!! you guys are true gentleman.. life is too short..

On the sensor thing, FYI. the W220 circuit is opposite other MB cars with the same brake sensor so jumping it oout will actually cause the light not turn it off.

Also to the OP. IF you have changed your from sensor and you stil have a light, then your rear sensor is the culprit. it is located on the same side R/H but on the rear brake.

Again, unlike the ML, disconnecting the sensor on the 2004 w220 cars for sure ( like mine ) will turn off the warning. Jumping them turns on the light.

And I must agree that they are very simple to change but if you forced the new sensor into A/M pads you may have inadvertently cause the two very thin wires in the insert to fuse together. This may be te reason you still have a light. I have noticed that on some A/M pads the whole is just a tad too small so be careful while inserting the sensor..

Good luck.

Quadcammer

I did not consider the aftermarket pad scenario because my sensor fit fine on my akebono pads, but you may have a point there.

Retarded. How are you going to try and promote shorting out the sensor? Just replace the sensor with a new one.. Cheap and easy.
