Zenon lights and dash light comes on 2007 335i

I have zenon lamps, and I was trying to get the inboard lamps to come on with the parking lamps, kind of like having running lamps, so took off the plastic lamp cover, and found an empty 12V source, where all the wires come from, when the light switch is in the 1 position, hooked up a jumper and YES the lamp comes on, but now I got a warning light on the dash, No problem just reset it, well I did and now the car on lift comes on in red. Service soon now lights up. tried to reset is and it wont let me

what to do now?

Yes I figured when I hooked up that guessing H8 bulb it threw a code


I hate it when a car is smarter than I am

well now the BRAKE light stays on in RED, got to see if that means the brake pads need replacing, coincidence or payback

I did take the jumper off the light, tried to reset it, still wont reset, I get to the Car on lift sign, the RESET light is on and a Check is showing, but it wont Reset,
I visually checked the brake pads thru the wheel spokes and it looks like I have at min a 1/4 inch of pad left

any suggestions besides me pulling the wheels and pulling the pads out

Take it a to a shop, get it hooked up to a diagnostic computer and find out whether you fried any of the lighting-related control modules. DIY if you have the necessary equipment. It's worth double-checking the monitored pads--inboard front left, inboard rear right--just to be sure but this doesn't sound like a coincidence. The sensor trips at 2mm pad thickness IIRC. You don't need to remove the pads unless they appear to be worn close to that limit, just remove the wheel and check through the inspection port in the caliper.

These cars use embedded systems to control a lot of things that used to be handled by simple switches and relays. They can react very badly when you connect power or additional loads in unexpected places. If you are lucky, the module that controls lighting functions (footwell module? maybe others) was merely confused by your experiment and needs to be reset directly through the diagnostic bus. If you're unlucky, you're looking at a few hundred bucks for a new module somewhere.

Well at the BMW place. They checked it out. And some one replaced the rear brake pads and left the sensor off. So they are replacing
The sensors. They are also doing the battery cable recall

Nice.

It's interesting that this seemed to coincide with your headlight experiment. Usually those sensors alert right away, or the system won't reset if the sensor is missing/tripped (they are one-time-use--the sensor trips when the rotor abrades away the tip). That's probably why you couldn't reset it the second time, but it's odd that you were able to drive around without a sensor with no warning until then. Coincidence after all--you lucked out!

Yes that is strange to me too. Especially since I took the Car to the same BMW Dealer back in OCT because the Aux input didnt work and it wouldnt recogonize the SAT radio, and they recoded the radio unit and cleared all the codes, you would have thought as smart as their computers are they would have picked it up then. Kind of makes me question the guys working on my car
