Brake Service Reset

[35i-Nut]

soo Im still messing round trying to get this reset , Front brakes showing -190 with plently of meat on the pads

Replaced sensor not so long ago

I have chopped up my old front sensor twisted the wires and plugged back in still wont reset :x

Ive read the sensor must read below 5 ohms if you stand a chance of resetting , mines on 0.4 Ohms

Apart from a dedicated brake reset tool , is there any other software that will reset it ?

Tried my OBD reader , Torque app etc

I did buy some INPA and NICExpert software on Ebay but its useless , E89 not listed

Will the Carly Android app reset it ?

For anything related to the E89 you can just the E90 menu in INPA. The INPA menu is just a shortcut system made to make the user experience a little easier. It's the modules within INPA that are the important part and the E90 shares most of them with the E89 as they are on the same platform.

Regarding the brake reset. I think the problem you are having is down to an incorrect reset procedure. You can find plenty of info by searching the E90 forums about brake resets. You shouldn't need any special tools if done correctly, just a service reset using the hidden menus within the car itself.

Many thanks for the info , will have another go at trying a reset

I think I did actually try a reset with the sensors also disconnected but couldnt get them to play ball

I never managed to reset mine after fitting new rear discs and pads even though it was not in negative numbers. My car was advising me to change them. Fitted a new sensors twice and it still didn't work.

Eventually the car decided the pads were good again and the counter went from 500 miles up to 1600 and has now increased to 1800 !

So random and annoying I had a full diagnostic kit when doing my rear disc and pads and the car was in brake service mode because of the electronic hand brake but it would not reset. Did ask at the main dealer and was told by the reception it was because I had fitted Brembo discs and pads

It's not beeping at the moment or showing any warnings so I will attempt to reset it again when I am next at my uncles garage and can try using his diagnostic kit again. I have read since you have to unplug the sensor reset the service counter plug the sensor back in then reset again so may try this.

My car doesn't have idrive. Doesn't really bother me at the moment as I know the brakes are all good and have been done but it is frustrating.

Yeah the warning messages are getting me down ! , will update if and when I can reset the stupid thing

Well after a trip to the garage and an attempted reset with snap on scan tool which failed , after reading some more on the E60 forum I took the Ebrake off then carried out the normal reset , took 2 attempts but reset

So if you are struggling with resetting your Z4 and have fitted a new sensor - TURN THE E BRAKE OFF !
