Brake Pads Worn to Minimum Thickness warning both FRONT & REAR / HELP!!

Yesterday I got in my car and the warning came up on my idrive (also red BRAKE light came on in instrument cluster):
"Brake pads worn to minimum thickness"

The reason I find this odd is that both the front and rear warning came on at the same time. When I go into idrive service options there isn't any mileage stated by the Brake Warning indicator

2007 335i
41,500 miles

Any info would greatly help

And to my knowledge I am not sure if the brake pads have been replaced as I have only owned the car 6 months. IIRC when I had the rims off the pads looked like they had a lot of life left on them.

Thanks

When you look at the service intervals are there -------- for the mileage left? I get this about once a year and I have to reset it with my BT tool. If you don't have one the dealer will have to reset it if the light bothers you that much. I think they will charge about 75, unless they do it under good will since the CBS computer has shit the bed.

I have over 50k on my 08 335i. I replaced my rear brakes in March and the front brakes will get done soon. No warnings for me.

this is most likely because the sensor that they have in the brakes is worn to the point it may need to be replaced not necessarily the brakes themselves. I am currently in the same situation and just going to order then they are about $23 a piece on ecstuning.com and should be oe

I have the same problem, however I got this at the begining of the year and replaced them only to find out there was still a ton of meat left on the pads and the sensors weren't even touched.

I replaced it anyway and put new sensors in and reset the warning but same warning keeps coming back after a few thousand miles, and I keep resetting...
Odd part is that it always says front AND rear are worn...

Any clues?

There is a software update to this glitch.

Not any more, there was a tsb for it way back near the end of 07, beginning of 08. My 07 had keept doing this when I had 6000 miles on it. I had to wait a couple months until BMW provided the software fix back in the day. I don't think CPO covers software updates. But being an 07, you would think the car has had full update by now.

It's possible that the brake wear sensor is loose. That happened to me and I just had to get a new one installed. The best option is to take it to the dealer (or a trusted BMW tech) and have them check it out. We're only speculating. When it comes to the safety of your car, it's best to have it looked at by a pro so you know for sure. Then decide what to do once you have the facts.
