Break pad sensor problem

So my break light is on because the car thinks my pads are worn. Car has all new break pad and rotors. I've tried resetting it but it just shows the clock then doesn't reset still shows "————" for miles. Sensor doesn't look worn but maybe I'm wrong any help would be great. Also if I can't get them to work I'm going to just cut them and put the wires together for now because I can't get sensors till next week.

Front or rear? And did you replace the sensor when the brakes were refurbished?

The pic you provided shows a worn sensor.

Rear and No I never replaced them. I just thought it was weird the car said the pads were worn. Before I did the breaks it was fine then a week after I did the breaks I got the error. How do you tell it's a worn sensor so I know ?

Cutting off the sensor. Do you put black electrical tape over a CEL?

Replace the sensor. When the circuit is open, the light is triggered.

Good lord. Okay, so first off, the correct word for the mechanical apparatus that slows the car down is BRAKE, not break. Go look it up for further explanation.

Second, the brake pad sensor is a plastic, consumable device that has a simple electrical wire circuit which breaks as the brake pad is consumed over time and wears down (thins) until the wire circuit in the sensor no longer passes electricity. Once the circuit breaks, a red "Brake" light illuminates on and stays illuminated until the brake pads are replaced along with a new sensor. If your brake pads are a week old, buy an new brake pad wear sensor and replace it. The system can then be reset.

Yeah obviously so I cut the sensor and connected the two wires. Did you not read the first post I said I won't be able to get a new sensor for a bit. And FYI the problem is fixed by bypassing the sensors.

You didn't fix the problem. You patched it over with a band aid. The problem is the sensor was broken and you needed to replace it with a new one. That's a perfectly fair question, but honestly, the way you write makes it difficult to help.

Just leave wire connected together.. What you are saying is you need to reset break service history.. I believe you can do it in BC hidden menu. We been running cars for 100+ years without these sensors so no worries ..

It's called the difference between doing things correctly versus doing them half-assed. Whether it is the proper use of nouns and verbs or repairing BMWs, Hass is the former and you obviously are the later.

True, but BMW has been using brake pad wear sensors for over 40 years, yet the disc brake was introduced to the mass-produced automobile in the mid 1950s and didn't become somewhat commonplace until the mid 1960s. So of the 50 or so years disc brakes have been commonly found as standard equipment on automobiles, over 80% of that time, BMW has been utilizing the pad-wear sensor as a safety device.

or...

If you got some 19's all you need is you eyeballs.. Well maybe some glasses for you old timers.. But hey if you dont want to inspector your car from time to time than a were pad sensor is for you.. I can see why BMW used these considering who there customer base is.. But for us commoners its not needed, we can do without.. So there is two different people in this, followers and leaders.

lol. no, there are two different people - the kind that cut off sensors and cover lights with black tape, and the kind that actually fix the problem. the sensors cost like $10.

"I don't need these new fan-dangled sensors!" (that aren't even new)
- in the same breath - "you guys are old for relying on these new sensors".

As I was corrected these sensors are not new... You say to do it right does this mean that 95% of the cars on the road are wrong for not having these sensors?
So they should install these sensors if they don't have them? You have these sensor on all your vehicles? If not does that mean that you yourself dont actually fix these issues?
And yes ten dollars a piece is a lot of money for an party hat trick. I stand by my statement, if you actually work on your car, theses sensors are a waste of money.

yes, I do have these sensors on all of my vehicles (3 BMWs of varying vintage), and yes, they all work because they are inexpensive, easy to replace, and a good way to know when the brakes need serviced.

Replacing all of the pads and rotors is an order of magnitude more than $10, it's easy to just include that in the price - like replacing the rotor set screws so they don't get rusted in place next time I need to touch them. Plus I'm not paying labor, so it easily makes up for the cost.

$10 is not a lot of money; if you think so, you probably shouldn't own a 10 year old 335i, it's going to cost you a lot more than that.

I don't think that people that encourage people to waste there money on a unneeded part just cause it's there should own a e9x. So we have that.
