E89 N52 - Brake pad light does not go out after replacement
Posted: Wed Aug 23, 2023 7:02 am
Hi,
I have a 2009 E89 23i and here's my problem:
The rear brake pad light appeared on the dashboard, so I changed the pads and the sensor (from Bosch) and do the reset but the warning still there.
iDrive said that everything is OK, 27000Km and 60000km before replacement for the rear and front pad, same thing on the dashboard but I still have the message that I must change the brake pad.
I first thought it was a sensor problem so I bought a brand new from BMW with no result.
Then I replaced both sensor (front and back) by a wire, unpluged the battery, wait half an hour, with no result.
I found someone with ISTA, I tried to reset the rear brake pad and it was a failure.
It has 2 faults, front and rear brake pad. When we delete them, it comes back.
It also said that the front pad are 90% and rear 48% (?) from new.
I checked the voltage on the sockets of the 2 sensors and they are both 10.7v, so I don't think it's a wiring problem...
The only thing I changed on the car was adding a MMI Android Auto box, I will try to uninstall it this week end, just to be sure.
I would be delighted to hear your opinions, I am demoralized, it does not go on the road anymore, it was refused at the French MOT because of that.
