Re: porshe boxster brake pad wear sensor
The pads may need adjusting...However the physics behind all this says that when the pads are wet...there is reduced Friction...and hence lower braking power...this may be perceived as a worn out pad when it is wet....Try apply the brakes to dry the pads when driving and the sign should go off...

The brake wear indicator is a small metal stone-like sensor that attaches to the brake pad. Once the pad wears down to a certain level, it begins wearing into the sensor, breaking the circuit open.
Once the light has come on, the appropriate sensor (front or rear) must be replaced to return functionality. Factory brake pads usually come with new sensors. Aftermarkets do not, and often have no provisions for attaching them either.
Alternately, you can bypass the brake level sensors by splicing the two wires for the sensor together. You will no longer have brake level warnings if you do this however.
turn on the ignition (not starting) and then press the littlie button in front of the odometer display for 10 seconds until you see the service indicator menu. use the stalk on the left and the up and down control to scroll thru to the front and rear brake pad picture and then press the end button on the stalk for 3 seconds until reset comes up, then it will show a little click spinning around, then release and press for another 3 seconds. This will extinguish the brake service light. This is the same for all service lights, but remember to turn off the ignition on and off for each reset Ie: for brake, for oil, for pollen etc. If not it might not recognize the reset. The pads on the 116i or should I say the indicator is crapo, in a extra crapo sense as it has at least 10k miles on the pad but the wear indicator shows it as need replacing, The handbrake light on symbol will be amber then red and stay on all the time until the sensor and pads are changed. Pads and sensor must be replaced together as sensor has resistance built into it it will be around 500ohms ( I think) when it has just touched and less with more wear, the new sensor is probably 1k ohms from each wire ie from one wire to the other = 1k ohms.In short the pad wear indicator is a rip off, there is a lot of life left in the pad when the sensor goes off. I estimate just above 1/3 left but more like just below 1/2.... BMW STICKING TO YOU AGAIN.
of course this is normal brake last around 12000 if you a like on the brakes some people are always on the brakes and go through brake pads every 2 to 3 month lol,, the front are at least 85% of the cars braking power so thats why the rear brakes last a lot longer, if you buy the parts yourself they are pritty easy to fit. if you wont me to give full instruction on how to change these I will do this would save you alot of money
Make sure the brake discs are still within spec, as they usually only last the life of one set of OE pads.
Make sure your brake pads has the recess to accept the clip in wear sensor on the inner Right rear brake pad, and front drivers inside pad.
If you have refitted these, and it is defective, you may need to replace it.You can disconnect the lead and check you have continuity. - You should have on a good sensor.
When the pads wear past 2mm, the discs slice through a small plastic bump - and break a wire link - thus the light comes on the dash.
After replacement of wear sensor, leave key in 'on' position for a couple minutes and the light will go out.
If this solves the problem, please rate as a Fixya! so others may benefit. Thanks.
